Yaqin Tube Buffer

I just purchased the Grant Fidelity 283mkii which I believe is the same unit as the CD3. The reason I purchased this model was: (1)It has a on/off power switch. (2)It uses 6SN7 tubes instead of the 6922 family of tubes. The stock chinese tubes sounded not so good, so they were replaced with some electro-harmonix that I had on hand. (much better) I am very pleased with the sound of the unit which is connected to a solid-state integrated amp. It introduced a very noticeable amount of "tube sound" into my system.... I would definately recommend the CD3!

I Disagree a little with the above posters. I owned the (2) tube 6sn7 unit. It is very "tubey" and made a dramatic impact on my system. (not all good, but not bad) I then tried a single tube unit and the difference was subtle, but the improvement was very nice. The single tube unit reminded me of my old Audio Research LS-2 Hybrid pre-amp. In short, I prefer the single tube model.
