I just posted this on AudioCircle and I thought I post it here as well:
Asynchronousity...? The QB-9 vs. the SE
I had an interesting experience recently. I had a chance to pick up a slightly used Ayre QB-9 DAC at a very fair price. Having read many positive reviews on the Ayre and the "obvious" benefits of asynchronous technology, I bought the QB-9 so I could compare it head-to-head with my Tranquility SE. After about 8 weeks of A/B comparison, the Tranquility SE emerged the clear winner.
We (my wife and I) would be hard pressed to single out any aspect of the QB-9's presentation that we preferred over the SE. I don't know, perhaps the bass was a tiny bit more articulate? But we preferred the SE in every respect. Overall, we both felt that the SE had a far more organic nature. I don't know how else to explain it. My wife said the Ayre, while very good, very accurate, sounded like a "computer"; too clinical. I could not disagree.
To be honest, I bought the QB-9 expecting that I would prefer it to the SE, which is why I held on to it for 2 months! I actually wanted to prefer the QB-9. I felt that the Ayre's ability to handle hi-rez files and the fact that it was an asynchronous DAC would surely make it the better choice. But every time I placed the SE back in the rack it was an effort to listen critically. I found that I'd tend to end the analysis and start enjoying the music. The SE exhibited more air in its presentation, better imaging, cleaner and clearer highs and that fabled Tranquility mid-range. It is both liquid and detailed in nature. Note that the SE took 100's of hours to get to this point. I've never experienced a longer break-in or more profound metamorphosis in any piece of equipment I've owned.
When I finally decided it was time to part with the Ayre, I received the usual "why are you selling" inquiries from interested parties. Whereby I would explain my impressions and experience with the Ayre vs. the Tranquility, HiFace, modded HiFace and a CA 840C I used to own. It's interesting that the gentleman who bought my QB-9 could not fathom the idea that any DAC lacking asynchronous technology could possibly sound better than an asynchronous unit!
But then again... that was me... roughly 2 months ago.
