Almost every solid state class A or A/B power amp in existence (not class D) uses discrete circuits....they all sound different....from two dimensional grainy to holographic real. So using a discrete output stage is no guarantee of sound quality.I do use a monolythic device as our main output stage. However, it is not a traditional op amp with super amounts of feedback (put any op amp number here, like a 627 or 4562 or 8620 or whatever). This device is a super high current high speed amplifier, used only once in high end audio in an over $10,000 preamp. This device does not sound like an op amp nor does it have any sound that I can hear. This device implemented with full dual mono power supplies sounds so much more 3D, analog, beautiful, extended, and dynamic than even the best op amps I have heard....and I have heard most every one of them.
Even having the worlds best sounding output stage in something does not get you great sound.....in a player there are five main areas that ALL need to be addressed for great sound: Power supplies (all of them), output stages, clock, transport and esoteric mods. I spend an hour just modding the transport in the Oppo and the difference is startling in analog out, digital out and HDMI out for sound and picture.
