Has anyone heard this unit? Does anyone know how this unit is supposed to compare to their all in one players?

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. Logged
Tony,

As you know, everything is so system dependent... but I was very happy with the 840C (DAC input) for quite some time. I used it with the HiFace, modded HiFace and Halide Bridge, and the 840C was very responsive and revealing during each phase.

That said, the Tranquility DAC removed the digititis, or etchy top end that always seemed to plague the 840C. The Tranquility is just in a completely different league. I also prefered the QB-9 to the 840C, by a wide margin. The Ayre is a great DAC, but the Tranquility SE took my system to another level. I'm spending WAY more time listening these days!

To Dracule1 and Jylee,

I bought the QB-9 (here on AudiogoN) for exactly the same reason Dracule1 wants to obtain one. I wanted to do a shoot out with my Tranquilty SE; I wanted a Hi-Rez capable DAC; PLUS, I wanted aysncronous technology based solely on all the reviews I'd read. As mentioned earlier, I took about 2 months to listen to both the QB-9 and SE with all types of music. Everyone who heard these two DACs in my system prefered the Tranquility SE.

I have absolutely no affiliation with any manufacturer and I'd be more than happy to discuss any of my observations and experiences with any fellow AudiogoNers. Just drop me an email! I learn something everytime I talk to another audiophile --- and there's certainly a lot left to learn!

Best Regards and Good Listening!

Jylee,

It would seem your terse remarks are directed at me. And I don't really understand your tone. I did not "resurrect" this thread to promote the Tranquility DAC! I posted my remarks after I bought an Ayre QB-9 and conducted two months of A/B comparison to the Tranquility. I've learned much from fellow audiophiles and I try to offer my views, where appropriate, when I can.

I suggest you try to give the Tranquility and Ayre pieces a listen. Or try to be open-minded enough to defer evaluation to folks that have.
