Absolute top tier DAC for standard res Redbook CD


Hi All.

Putting together a reference level system.
My Source is predominantly standard 16/44 played from a MacMini using iTunes and Amarra. Some of my music is purchased from iTunes and the rest is ripped from standard CD's.
For my tastes in music, my high def catalogues are still limited; so Redbook 16/44 will be my primary source for quite some time.

I'm not spending DCS or MSB money. But $15-20k retail is not out of the question.

Upsampling vs non-upsampling?
USB input vs SPDIF?

All opinions welcome.

And I know I need to hear them, but getting these ultra $$$ DAC's into your house for an audition ain't easy.

Looking for musical, emotional, engaging, accurate , with great dimension. Not looking for analytical and sterile.

Guys, this is not a matter of flat vs not flat. We are talking about crazy expensive, top tier product in all directions. I'm sure all of them are "flat" from the sublimely low frequency to the ridiculous ultra sonic. It's not a matter of specs, and I don't believe it's a matter of distortion. Every speaker I have heard, tried, or purchased is considered state of the art, whether it was to my taste or not. To say that the Avalom Isis or the Vandy 7 or the Dynaudio Comsequence has more distortion or isn't flat or is in some way colored is pretty much ridiculous. These speakers are all designed to the best of their perspective companies abilities with their particular take on Uber Speaker design, acoustics, psycho-acoustics, phase/time alignment management, voicing, etc. Add to that the fact that even the worlds perfect speaker will sound totally different in my room versus your room and it makes the whole damn process that much harder.

The Trenner & Friedl Isis is simply voiced differently then the CU. It has different priorities, completely different design and different psycho-acoustic properties. As a result, it does 28hz to 40khz flat and throws a soundstage you can drive an RV through. It's voiced a certain way and accomplishes it's particular goal with great success. It does this with simplicity, elegance, refinement and is utterly understated. It is the warm cabin on top of the mountain with a roaring fire, a well broken in leather chair by the blazing hearth and a glass of Cognac VSOP that is that perfect temperature to simply float from the glass and evaporate relaxation onto your palate.

The CU is a masterpiece in engineering and complexity of design, crossover implementation and artistic beauty. It applied over 30 years of continued success from a brilliantly unorthodox design and improved upon it. It is not understated nor is it overzealous. Although brimming with drivers, it's nigh impossible to identify anything other then a unity of sound, a meticulous amalgam of perfection that paints a picture as if from a single brush stroke. Yes, the colors are more vibrant then those chosen by Trenner & Friedl but equates to comparing the spectacular colors of a sunset over the ocean as the sun descends just to the horizon to the majestic flow of heather and wheat during a gentle breeze at the base of a grey and white mountain range of breathtaking beauty. One is simply not better then the other. They both touch the sole and enraptured the spirit.

It's a nice place to be- deciding between those vistas. No bad choices, only choices.

An extended audition is truly the best way to tell. I would call an extended audition a purchase. The beauty of it is that if one finds its not all it was initially, the other option is just a sale and a purchase away....
CTSooner - my final decision against the Vandy 7 had to do with how their low frequency driver is implemented. I understand all the tech behind the low frequency signal attenuation prior to amplification and the fact that it "theoretically" conveys the voice of the amp to the woofer but I don't believe it to be 100% effective in real life application. It works, but it's best implementation would be with Vandys own amps. I wasn't ready to give up completely the magic that comes from my Burmester Amps in those lower frequencies. I also didn't love the down firing, side ported design. I heard it and felt it but I did not get that direct radiation I prefer. In the end, It was just a matter of implementation and preference. They are sensational without doubt, but I found other choices suited my tastes more.
Matt, I think the discussion was circling around the perception of the Isis as "rolled off" and what that actually meant in terms of engineering. The fact that the room played a roll is very interesting. Still more time on the stove for the Isis obviously.

Manufacturers of electronics regularly quote distortion specs. Speaker manufacturers do not. There is a reason for that. They are distortion machines...:)
It seems clear both the Trenner- Friedl and Dynaudio are world class speakers. As mentioned before, different design philosophy yielding different sonic characters (as one would expect). Matt's earlier amplifier analogy and follow up detailed listening comparison sums it up effectively. Both superb speakers. One appeals more(emotionally) to the heart and soul, the other has outstanding cerebral appeal without being guilty of analytical sterility. So it's a matter of which wears better long term? A listener's inherent bias/taste will determine that. This speaker journey has been fun and interesting to follow.
Hmmmm... Matt, You seem to be in the horrid position of having fallen in love with two divine girls! ... Oops, I meant speakers!

Which one will be your girlfriend... Double Oops, so sooorry, I meant... Which one will you choose?

May be... Marry both?!
