    Thank you, Erik, that is very helpful!

    If this is indeed how the Onkyo works, the Pure Direct mode really makes sense. If it only bypasses the standard tone controls and shuts off the display, it's more of a placebo.

    Sometimes a picture is the best way to convey a concept.

    Glad to help.

    As noted elswhere - this may NOT be the way EVERY avr works, but for many this is the design - which has ramifications that some people get confused over.

    Like - when you use a TT with an avr and select Pure Direct, the sub shuts off.....because that is how Pure Direct was designed - not that there is a hidden function someplace that will turn it back on in Pure Direct.

    It is sometimes maddening and frustrating to navigate the confusing morass of features on modern equipment - almost as if you need special training or a degree :p

    The TX-8050 has both a Purd Mode and Direct Mode. I don't think "Pure Mode" is nessasary unless a video connection is engaged. If we're listening to just audio then Direct Mode is enough. But it not only bypasses Tone controls but also byasses any mixing to 2.1 for the subwoofer. I always thought these features were most useful for connecting to a device that has it's own DSP.

    I think it was a PP-1. This stuff is dirt cheap from a components perspective, and certainly not magic, but yes 50 cents is an exageration. I've also heard that the PP1 is the same phono stage design going all the back to the 3020. Not to say it's bad (it's not), but a $15 phono stage would actually be damn impressive (to appear in a mid-tier integrated).

    Again, the 8050 isn't an AVR. There's no DSP, no ambient effects, etc, to begin with.

    Right on, and a standard, basic, well-performing phono circuit isn't an expensive thing to do anymore. There's some fancy stuff out there getting in to the MC domain, but for a basic MM the one in the Onkyo is perfect.

    (note, I actually replaced a Linn DSi with an 8050 last summer... while transitioning to my current tube-based rig. I was more than content and it frankly embarrased the Linn on value/performance).

    A fascinating study on audio consumer perspectives and assumptions, this thread.

    I would suggest that in the future, the OP avoid starting threads that essentially ask the question, "What happens if I push this button?"

    I have that feature on my pioneer elite and have used it but not in a while so I guess that tells me I'm not hearing an audible difference but then I have everything set to flat on my ht and my 2 channel.

    I have the same Onkyo receiver and like it very much. Don't worry about replacing it.

    I have an Onkyo PR-SC886 Pre-Pro. I generally use it only for 5.1 stuff via HDMI. But I do have it hooked up for 2 channel stuff if I choose via HDMI or rca's (depending upon the source). I don't use Pure Direct for 5.1 because I need to do some processing for balanced 5.1. But I can tell you that for 2.0 in Pure Direct Mode, it makes for a pretty decent pre-amp -- and there is a considerable difference between the Pure Direct mode and the other modes. Purer tonality, better imaging, more dynamic, better separation. Frankly there's very little separating it and my analog 2.0 pre-amp (PS Audio PCA-2). If I had to guess, I'd say the Onkyo Pure Direct Mode (in this model anyway) is not a marketing gimmick and is truly taking quite a bit of garbage out of the circuit.

    This particular pre-pro can also do DSD without conversion to PCM -- but only in the pure direct mode.

    Not OP's fault that those weighing in knew beans about the 8050.

    Then you'd be a bit of a mug. The TX8050 is well capable of taking on the likes of the Marantz and bettering it. Had mine for over a year now and love it. Form and functionality in one package. A quick scan over the internet's various review sites will show how much this under-the-radar amp is liked by its many owners.

    Oh and, if you're thinking about trying some underpowered valve thing, fine, the Onkyo delivers 100wpc, a nice neutral presentation and lets the music shine through. The quibble is...? Ah, it's mass market. When will folk realise that the days of the bog standard integrated has been numbered for some time?

    You got that right mate. Having heard it, and used it extensively, it's one of the best hifi items of the last few years IMO.

    I have an Onkyo 8555 with both Direct and Pure Direct. I can't hear any difference with either setting turned on.

    The whole soundstage opens waaaay up on the 8050. Far more depth.

    Some of the Internet Radio devices do include an FM tuner including my Aluratek WiFi Clock Radio and you also can get a separate AM/FM tuner.

    The "Flat" setting in an EQ and Direct Mode built into a receiver are basically the same thing.

    Direct Mode, is the mode you use when you tell audiophiles, how dedicated you are, and how all tone controls are whack.

    Regular mode, is the mode you use, when others come over to listen and you realize you can actually make it sound better to most other people, and dont want them to think your system is weak or puny.

    A bit of sarcasm, but also kinda true.

    With my Arcam a65+ there's a massive, huge, clearly obvious difference when disengaging the tone circuit. I'll use the tone controls when the bass is a bit out of control on the source, or if I'm streaming a particularly bad sounding tune from Spotify. But otherwise on the Arcam I'll keep it disengaged as the tone controls tend to flatten the sound to a large extent.

    On my NAD pre-amp, it's a more subtle difference, as the tone controls themselves are fairly non-invasive and only shape the extreme ends of the eq curve, leaving mid range unmolested... I'm guessing between 80 and 14k... as it takes quite a lot of movement on the dials to hear any difference. I actually wish it were more aggressive.

    I also have this receiver and see no reason to upgrade at this time. I listen primarily to records (LPs or "vinyls" if you will).

    Do what is right by your own ears. But I find the Pure Audio to be the best setting for stereo recordings, whether analog or digital, with my humble setup. The only other mode I use is the Mono mode for listening to old (obviously) mono records-it helps cancel out some of the noise on older vinyl and "shellacs."
