    This post is mainly a foray into the cyber equivalent of thinking out loud as to what could work and what would be an unmitigated disaster. For the avoidance of doubt, I'm at the stage of getting as much info together and then heading off for demos. Constructive thoughts and observations are welcome.

    Having started looking for new speakers, I've decided a slight diversion ( :shrug: :) ) is needed to sort out the amp department first - 2 channel stereo. Preferred total budget is GBP £3,000 all in (i.e. 1x integ amp or 1x pre + 1x power).

    Current amp is a fully integrated Rotel RA-1572 (including on-board DAC) with Q Acoustics Concept 20 speakers (on the list to upgrade later). Sources are both digital and analogue. The majority of listening is to rock music ranging from melodic (e.g. Floyd, Genesis, Porcupine Tree) to heavy, even the odd piece of metal (e.g. Metallica / Evanescence) but pop-rock and classical also make appearances.

    Another integrated is a possibility but I'm open to a two box pre/power amp combo.

    For features, some are definite requirements (for me) whilst some would be preferred (aka a nice bonus). In no particular order:
    - tone controls (definite)
    - 2x speaker posts for 2 spkr sets or bi-wiring (preferred)
    - A/B spkr switch (definite with 2x spkr posts)
    - headphone socket (definite)
    - 2x optical inputs (definite)
    - 2x coaxial inputs (must have at least 1; 2 strongly preferred)
    - USB asynch (not critical)
    - 1x HDMI (strongly preferred but not critical)
    - 2x analogue inputs or 3 if including phono stage (definite)
    - onboard phono stage (not at all critical)

    Integrated amps still in the running: Parasound Halo HINT 6; NAD M32 Masters. I've read enough to know the M32 beats the HINT 6 hands down for features BUT, a general consensus seems to have formed that, relatively, the HINT 6 delivers to a higher level sonically.

    Pre-amps still in the running: Parasound Halo P6; NAD C 658. The P6 is pretty much the same as the HINT 6 sans the power unit. BUT, as a pre, it gives greater flexibility for potential future changes and leaves the door open for a non-Parasound power amp that may or may not out-perform the Halo A23+ power amp which, on paper is the natural pairing for the P6. The NAD is once again feature rich but I've seen reports that the sonic delivery tends to clinical, even harsh on occasions. The PS Audio Stellar Gain Cell would have been a real contender but I really need that second optical in as well as tone controls.

    Power amps still in the running: Parasound NewClassic 275 v.2 (90W); NewClassic 2125 v.2 (150W); PS Audio Stellar S300 (140W). I haven't found much feedback for the NewClassic amps but the write-ups for the Stellar S300 are hugely positive. There is a decent consumer review where the user compared the A23+ with the Stellar S300 and s/he indicated the Stellar edged the A23+ for scale. Unlike the A23+, the Stellar and the NewClassics have 2 sets of spkr posts.

    Budget wise, the Stellar S300 is just about doable with the P6. If the NAD C 658 (pre) could be made to "sing" by the Stellar S300, the boatload of features would make the NAD hard to resist (notwithstanding one or two known software issues).


    I don't mind re-opening the door to possible alternatives so long as they provide the features I'm looking for.

    If you're able to offer any info / insight, great. If not, no problem - thanks for reading. In any case, happy listening all.

    Catcher10 I like records, and Prog...duh

    All good choices, I can only state that an audition would be a must. The PS amps are Class D vs the Parasound are Class A/B.......have fun

    Take a look at the Marantz PM-8006 integrated amplifier, made in Japan. Just purchased one recently. It has 3 separate tone control knobs for treble, midrange and bass attenuation. Don’t know if it checks all your other boxes, msrp is $1,200USD. The Marantz Reference Series PM-14S1 integrated also made in Japan has even better sound and build quality, msrp is $3,000USD. I have two and speak from experience. Don’t know how many boxes it checks for you either, but both are stellar performers.

    What are you looking to achieve by changing your amp? I have the Rotel 1592 which I believe is just a more powerful version of yours. These are truly excellent amps with superb measured performance and all the features you need.

    Fair question. For the most part, the RA-1572 sounds, well, really good. It has a great 3D soundstage with real depth and drums / percussion hit home with real authority and there is plenty of "air" in the audio picture. Contrary to the rather strange review in "What (do we know about) Hi Fi", I also found the timing to be perfectly decent. However...

    There are two main issues that no amount of tinkering with the tone controls will overcome such that retaining the Rotel would be within reach. Firstly, upper-mid range piano strikes sound as if they are coming from under a cover of 2 or 3 blankets and I haven't been able to find a way of changing that without completely messing up the rest of the soundscape. Secondly, when listening to busy rock music, especially with metallic / jangling guitars and the likes of the heavier passages of material by Metallica or Evanescence, the guitars take on a distinctly emphasised metallic edge which seems pulled to the centre of the stage whilst, at the same time, squeezing out the bottom end to almost nothing. I can't recall these issues being within any other set up I've experienced. I've even A/B'd the Rotel with my previous amp (I still have a Cambridge Audio CXA60) and whilst the latter lacks the same level of depth and authority compared to the Rotel, piano sounds definitely sound more "natural" and there isn't the same condensing / squeezing when playing the same heavy rock material via the Rotel. Just today, to check yet again, I played a song ("Dark Star" by Fish from the album 13th Star) and this perfectly illustrated the second issue. Same results with sections of "Enter Sandman" by Metallica but, to show it isn't the mastering of a whole CD at fault, I also played "Nothing Else Matters" which sounded really good. Contrast those with, say all of "Wish You Were Here" (album - 2011 remaster) by Pink Floyd, and you'd never guess there were issues with other material. WYWH sounds great on the RA-1572 - including the guitars on "Welcome To The Machine".

    For completeness, I have played around with speaker positions to no avail, albeit within the limitations of available space.

    For most types of music, the RA-1572 will sound rather lovely. But, it just doesn't like "busy" "jangly" heavy rock and there is just enough of that in my music collection to prompt me to look at alternatives.

    Not sure that's quite what you expected @keiron99 :) . Anyway, I look forward to achieving musical nirvana soon. So long as I manage to get the all-important right cables of course... :shh: :D

    I've been looking into the Stellar M700's myself. The reviews I've read said any sign of "class D" does not exist in its sound. Paul Mcgowan, owner of PS Audio, stated (paraphrase) he thinks the best class D (like the Stellars) can get to 90% of the worlds best class A and A/B. Of course Paul wants to sell amps. However, if watch many of his videos, he seems to be honest with strengths and weaknesses of his own components vs other brands.

    I'm running a fantastic Class a/B Nuforce STA200. If I did not listen to all kinds of music, I would be happy for life. Rock, Electronic music really shows the strength of the amp. I just wish it were a little more refined in acoustic, jazz and lighter classical (The STA200 does great with big, thunderous classical music).

    A sweet choice and a good technical match would be the Rogue Audio RH-5 headphone / linestage amplifier combined with the Parasound a23+. Will give you a slice of the 3d smooth sound of tubes and the option to change the sound to your liking by swapping them if you need.

    The Classe Sigma 2200i integrated (with DAC, USB and HDMI inputs, and digital bass management) is being offered for US$2745, half the original price, by Listen Up Audio. If you have TAS, see page 188 in the May/June issue. I have heard the Classe CA-2300, which I found excellent at keeping tonality constant with increasing complexity.

    I don't know if this is a practical option for you in the UK, but perhaps....

    Just a minor update. Many thanks for all the suggestions so far - I have looked into ALL of them and even where the products didn't necessarily meet the spec set out in the OP, they did provide food for thought and got me looking at products by other manufacturers.

    Although still looking, a couple of considerations mean I'm now waiting until later in the year before pulling the trigger. Firstly, the feedback on the NAD C 658 continues to be mixed but the features are so tempting that I'm prepared to wait and see if the software glitches and delay(s) in implementing DIRAC are resolved such that the NAD C 658 is fully functional AND sounds great. Secondly, @Mike-48 's post got me looking more closely at Classe and I noticed a new "Delta Series (by Classe)" of products is under development which may well be available this year - it makes sense to see if that range has something of interest. Having checked, there are enough Classe dealers in the UK for demos and purchasing to be a practical option.

    In the meantime, there will be plenty of thumb twiddling and lots of fun figuring out which wires cables shall help to reveal the true glory of the mightily awesome output of the boxes that eventually make it into the new system.... *cough* It's tempting to promise not to start a(nother) thread about cables but there is a little mischievous voice in my head that suggests it would be so wrong to offer such a guarantee :yikes: :uhhuh:.

    I just bought the Parasound 275v2. Very happy with it. Compared to my Adcom 535L, it is a slightly warmer sounding amp and slightly more powerful..but not a ton (Adcom 60/100- Parasound 90/150). I liked the feature set more than Emotiva. You can bridge them and still run a 4 ohm pair of speakers like mine. That is what I will do in the future for 200wpc. Or I might go the Bi-amping route. It also runs two sets of speakers for my old/classic Stax headphones. The slim profile is very attractive and it is surprisingly heavy when you grab a hold! Plus it was a great deal from Safe and Sound, which is authorized for Parasound.

    I’m running a recently acquired P6 and an A21. It’s a killer setup and I have been pretty happy. I was intrigued though by the PS Audio products, and they can be had at a much lower cost than listed (if you call up a few dealers). I’ve heard that class D tends to sound better at lower volumes than your standard A / A-B amp, which is something to consider. What sold me on the P6 was the features.

    I'm trying not to be swayed by which class the power amps are but; lower running temps, lower power consumption and effectiveness at lower volumes aren't factors that are easily ignored (at least for me). If it's a shoot out between amps with differing classes, I'm hoping any differences in audio character make the decision relatively easy!

    On the pre side, the P6 features are definitely great but the NAD C 658 is even more feature rich and has greater flexibility. Again, I'm hoping the decision is made easier by significant differences in audio character. If both sound more or less as good as each other, the C 658 will win out. The problems start if the P6 edges the C 658 sonically but only by a smidgen! When I say "problems", this doesn't mean I've lost the plot in the context of a "world" perspective. Well, not completely.... :shh: :)

    As an aside, but far from irrelevant, NAD has finally announced that Dirac Live for the C 658 is scheduled for release in June 2019. Some might say something like "...oh jolly good, nice to see it's coming...". Others may say something a bit stronger such as "...about bleeping time...". The Live (or lite?) version is free and makes [audio] compensations up to 500 Hz. The pay-for "Full" version (currently US $99) gives "...room correction across the full frequency range."

    Dirac Live to Arrive for the NAD C 658 BluOS™ Streaming DAC in June 2019 - NAD Electronics

    If that schedule is kept, demos will commence soon after - with gusto :goodie: .

    First, if you want new speakers, then look at, and listen to new speakers.

    Now, once you have the new speakers in place, see if you still feel the same way about the amp. You really have no way to know if the amp will not suit the new speakers much better (or likely the new speakers suit the room and your ears much better). Then when and if you find that you are not thrilled with the amp when combined with the new speakers, look for a DAC and then an amp. Keep the digital and the analog separate. It'll be a mistake regarding technology and longevity buying an amp that integrates digital features. Buy digital devices for their performance and features, and then buy an amp (in the unlikely case that you still need one) for its performance, not features.
