    I've pointed this out to everyone I know who's got one, but nobody else seems to hear it...!

    There's a significant audible difference when switching to Direct/Pure mode on my Onkyo TX-NR3008. I suspect that most of this is due to Direct/Pure mode turning off the Audyssey MultEQ XT32 room EQ. I find that music sounds much more pleasing with Direct/Pure enabled (i.e. with Audyssey OFF).

    I agree with skriefal's post above.

    And will everybody else who doesn't own or hasn't heard this receiver quit talking about how surround sound receivers work (or don't work)? This model is not a surround sound device. It is a 2-channel stereo receiver with network capabilities. Just stop it, please.

    Hey all,

    Thanks for the responses. For the past week, I've been listening to vinyl with the Pure Audio mode engaged all the time, and I don't think I'll ever go back. It took a few days, but now I really prefer the more natural, direct sound. It's funny, human hearing can be such a subjective thing, but at the same time ears can also be conditioned or learn to like certain things.

    You have a good amp there. Upgrade when you can really afford a big step up, don't get caught in the low-end back n forth so many here engage in.

    I second the positive opinions on the TX-8050. I bought mine to replace and older Onkyo, (which still works perfectly), adding, on a budget, digital inputs as well as a convenient front USB port. I have been nothing but impressed. It reads pretty much any storage device I throw at it, including .wav files from large NTFS formatted drives, has a dead-quiet phono preamp, and quality sounding relays on the speaker/headphone switches (nice solid clicks). Plus the already mentioned "pure audio" mode. A steal at under $250. Maybe you could obtain marginally better sound for a lot more money, but I'd rather spend that on music :) Cheers everyone.

    I have a Yamaha AVR with pure direct and it sounds better, but I also have a higher end Technics (gasp! the horrors) receiver, in fact, the last model they ever made (2001-2002 time frame), and it has something where it processes totally straight, display off, no tone, nothing and sounds great.

    In Pure Audio mode on my Onkyo TX-NR805 AVR, the HDMI ports are still active(necessary when feeding DSD audio). The front panel goes dark, composite and component video inputs, bass/treble controls and Audysessy EQ are bypassed. Do I hear a difference between normal, Direct and Pure Audio? Not really but I usually will run the AVR in Pure Audio on most sources just to keep the AVR running just a little cooler. The 805 has a reputation for running hot under normal conditions and HDMI board failures.

    This is my most used solid state amp. Selector knob and volume, that's it. I love it and sounds very nice. A bit shy on the bass but with the right speakers I don't miss it and it has a tubey sound. Simple. a100II_super.jpg

    I can't use the Pure Audio modes on my Onkyo AVRs because it bypasses the sub crossover and I use a sub in my HT and office. My understanding is that the Pure Audio modes on Onkyo receivers, both multichannel and stereo, are well designed and do offer a very direct route from the preamp to the amp with no tone controls in the mix.

    Actually our cat had a spell on my cheapy sub and fried it, so now I'm 2 channel, I now have equalizer off and I've tried the pure direct, I notice not as good a soundstage with it engaged, so now it's just stereo, Audessey off, and I'm pretty happy, I may not replace the sub

    The Bryston preamp I use is on the bare bones side regarding features. I do long for bells and whistles. As far as high end audio goes, the manufacturers that utilize all the features you can think of are Accuphase and McIntosh in their preamps.

    Since we're talking about Onkyo, I really dig this preamp they currently have on the market. I first heard it at CES 2011. It sounded good to me. It also has the Pure Direct mode...it got a great review in TAS back in 2012.

    i have a "cheap as chips" onkyo cr-555 dab receiver..and love it. it features a "direct" function that does what it says on the tin...by- passes the tone controls.i have to crank the volume up a bit,but that is a little sacrifice for the gain.

    Haha, yes, precisely! Although as someone who now uses an Onkyo TX-NR818 for his all round listening duties, the Pure Audio and Direct modes work extremely well. I don't miss having a regular stereo integrated at all.

    It likely just by-passes the tone control circuits. The more you process a signal, the worse it sounds. It's passing through more transistors, capacitors, etc. Obviously that's a good thing to bypass.

    I have an Onkyo TX-SR604. The manual says it has 'Pure Audio' mode but not available in North American models, which is where I'm located.
    I use the 'Direct' mode instead and it sounds much better than 'Stereo' mode with EQ disabled.
