The comparison asked by you at the top was between the Complete and the Integre I assume. I have a Integre DT in my small home office system. DT is for dual transformer. It outclasses the Complete in resolution of low frequency information and bass extension. I think it goes back to my 4 ohm comment about. The single Integre has the same 4 ohm performance, but is not as dynamic as the DT. The second transformer really makes a difference. The DT sounds much bigger than the 50 watts it is. Also things like vocals and piano sound much more "real" with the DT. Stereophile has the DT in Class A, the Complete in Class B. The DT without phono now lists for $2350. I have MM phono on mine which lists for 2500. With MC phono is $2750. There is a used DT with MM phono listed for $1500 on Audiogon now, and a Complete with remote for $700.
The following was copied from someone elses review, but it sums it up well. (Aaron from McLean, VA) From the full review, it appears Aaron is right on point by using the single Integre, not the DT, but I can't be sure. If you go to AudioReview.com under the Complete, you could eMail Aaron and ask.
I must say that the Complete offers incredible sound for $1000. It has quick pacing and keeps up with whatever music you throw at it. It has a very revealing soundstage, keeping the instruments and vocals hovering right where they should be. It's almost holographic, giving you the sense of depth and ambience. Due to its quickness details are extracted for you to hear clear as day. The highs are also very nice, the have a sheen to the sound and are very extended, leaving all of the music information there for you to enjoy. Now, the weakness. What you sacrifice for the strengths above is the bass reproduction. It's tricky to say in words but the bass is there. You here the sound of bass but aren't offered the depth, weight, or realism of bass. Due to this the overall sound of the Complete is hollow or thin sounding. There is no weight to the quick sound. This prevents the Complete from giving the music the "it is there in front of you" sound. You know, complete realism. But for $1000, should I ask it to? Of course not!
Hears where the YBA makes the step up.
The YBA is rated at the same 50 watts per channel but offers one of the most realistic bass response I've heard with any product. This absolutely incredible sense of weight to the music is added. For the first time I actually felt like the music was in front of me. I don't mean the kind that
comes from "If I close my eyes and sit with my head exactly in between the speakers and say yeah, that sounds like what a drum should sound like." I mean that the instruments where tonally precise. The vocals where uncanny. The soundstage was hologrphic. I no longer had to look for it in the music it freakin jumped out and told me what music should sound like. I could no longer find any significant flaws, I didn't question the sound. It was all right there for me to enjoy.
