Worlds best DAC

Everything else in the system being the same... same room, same calble, same power supply, same ambinet temperature, etc., I am not sure how anyone can play a CD on a std. CD player and not hear a pretty decent difference between that and a nice DAC.

Once you take away the spinning disc itself, motor, laser pickup, power supply noise, jitter, etc. and just send data to a DAC and let the DAC do its thing, you will have a big difference ion sound. Not with all DACs... if you are still connecting to a DAC with USB, toslink, etc., you are missing out still. The LINN DS units connect to your network via CAT5 and just send "data" to the DAC for it do "go to work". If you are using a PC, laptop, etc. and a connection like USB or wireless to some other device, then through a cable, you are missing out.

My LINN Akurate DS will compete and usually sound better than CD players in excess of $10k. Not to mention that my entire library of music is at my fingertips via and iPad.

i agree with bflowers assessment of the zanden, but in its original version, rather than the current version.

the original had more of a classic tube sound. another dac worthy of consideration is an early version of the wavelength cosecant.

I would suggest finding a DAC that allows for opamp swapping. I have found that swapping out stock IC opamps for Discrete opamps (such as Dexa or Burson) really makes a big difference. While I still prefer analog, I have found that my digital listening experience has been greatly improved. I also like having the option to switch between SS and tube output. The more flexibility I have to customize the sound to my tastes, the better.

I have been invited to listen tothe Metronome Kalista Ref SE Thursday with the new Wilson Alexandria XLF and the D'Agostino Momentums. Will post.

Meanwhile, the more i think about it...the more i think hi-res has some ways to go...particularly on the music selection side. Since i already own the Zanden and have been exceptionally happy with it for the last 5 years...i might just look for a 2nd hand Zanden transport and be done with it for a few more years. While i think computers have done an incredible job of trouncing transports on a 'dollar per pound' basis, i still find the best SOTA transports (particularly ones designed to go with specific DACs) preferable to my ears. Plus, i am not a fan of trying digitize my whole collection...deal with crashing computers, backup files, etc...i just like to drop in a cd and push play and go back to work.

So i was (very kindly) invited to the introduction of the new XLF...superb room...D'Agostino Momentum monos...Kalista Ref CD player, ARC Ref 5SE preamp...Transp Opus MM2 Cabling throughout. On the face of it...a superb system and one to be reckoned with. Here's my view of the experience:

- Supreme 'density of signal'...greater by a 'meaningful margin' than Audio Exotics room in Hong Kong (Tidal Sunrays with 2 Tidal tower subs, 3 sets of Tidal Impact monos, Tidal Presencio, Stahl-Tek Vekian, Argento Master Ref cabling, Tripoint grounding/AC).
- This is where i think newer electronics have come a long way (and good speakers thought not necessarily 'the newest ones'...older SOTA is still amazing)...in being able to take the signal and through substantially lower noise floors, more exacting detail retreival...really are able to deliver a very strong, focused, concrete music signal. Older electronics...mainly digital...tend to deliver a 'weaker music signal'...almost like a flashlight where the batteries are getting low.
- On this system...it was like brand new lightbulb and batteries and flashlight. Very impressive.

- Better bass than i recall with X2 Series 2...but that's not a definitive statement because too many variables. What I CAN say for sure, is that this XLF will NOT replace any well setup X2 Series with a good sub. That is not close.

sound on tracks i know extremely well was 'a bit shouty'...which surprised me. I am going to give the system the benefit of the doubt and say there were probably more than a few new components...most likely the Ref 5 SE, as well as of course the speakers, and possibly the Momentums and speaker cables.
- By 'shouty' i mean that even on Amos Lee...on whom Norah Jones does background vocals so you get the idea...his voice felt a little like he was singing/shouting. And that was not the only track where i felt this touch of slightly raw overpowering force.
- Based on what i understand about the new tweeter, and what i already know about the X2, X2 Series 2 and likely the XLF mids, i might point at the Momentum monos which i have heard are 'slightly harder' than the stereo version. I am familiar with the Kalista, Ref 5 (non SE), Transp cables and the X-1, X2 series, so that is my guess.

i appreciate the opportunity to hear it, having heard the Audio Exotics Room last year with similar/same music. Feel free to ask/PM for any other observations.
