Can Mac/PC compete with High End CDT??

Dear All,

I want to believe (do you?) that the Mac or PC approach can work, at least be good enough. Being that my prime source is analog digital music is secondary but at the same time compulsory for recent and actual recordings.

Reading reviews and opinions floating around online I was curious to hear for myself in a high end system, a sort of A/B singular test was needed; away from commercial pressures and inexperienced ears.

Full of great expectation I head to a fellow audiophile's den, both of us motivated to get to the bottom of this question ourselves.

So we got ourselves organized and ended up with a promising menu: Esoteric P0, Weiss Dac 2 D/A converter, Mac with Amara/iTunes then Kondo Dac with the Esoteric P0 and then Weiss Dac 2 D/A converter using fire wire interface from Mac/Amara/itunes via the Kondo DAC.

All the “virtual music” was obviously uncompressed format.

Preamp Absolare, amp New Audio Frontiers Ref 845 and Acapella Triolon Excalibur and some very good cables.

Being used to the sound of Kondo electronics and Goto horns that furnish my listening room, fed by micro seiki SX8000, CEC TL0x Cd transport at 1st I must say that I was disappointed with the sound that the P0 was delivering via the Weiss Dac.

I will not be long-winded here: this was not good. The sound seemed broken, out of pace, lousy trebles, one-dimensional bass and very nasal voices.

The resolution of the electronics and speakers told the cruel truth in this 70m² dedicated listening room. No fine-tuning I have ever encountered could solve this even with the widest stretch of imagination.

So the Mac/Amara/iTunes? Okay no gain no pain! Here it was no pain all gain, I mean, it sounded the same including the flaws but with the added advantage of mac based music selection as opposed to cd loading. This seemed promising, made me jump to the conclusion that the culprit was the Weiss DAC, not the fire wire interface.

So in goes the Kondo DAC driven by the P0, okay! I will lack vocabulary here it is truly amazing. My host and I within the 1st seconds looked at each other, not even in the listening seats, we agreed with each other without saying a word! Then we let the CDs play on, simple as that!

We kind of played around here knowing deep down that the next step was the “juge de paix” (for those who don’t master French that is “peace judgment”).

So we wired the Weiss Firewire/spdif interface to the Kondo Dac using the Mac/Almara/iTunes.

As it stands I had spoken to Daniel Weiss (owner/designer of Weiss Audio) a few days before and he explained to me that CD transport and Mac/PC was fundamentally the same thing; delivering 0 and 1 and the interface was just passing those 0s and 1s to the DAC.

So? I may have to repeat myself here : The sound seemed broken, out of pace, lousy trebles, one dimensional bass and very nasal voices.

The Kondo DAC was telling us all about the sources. I walk way from this with knowing that Mac/PC is not ready to replace a CD transport in high end system dedicated to experiencing music and all the emotional treasures that it has in store for us to enjoy.

So what does this mean? I think that in certain preamp/amp speaker combinations the hard disk be it mac or PC may work and certain reviewers will confirm this. However, if that system resolution comes to change, that its goes up the ladder, then the flaws in this approach will become apparent.

It would be advisable to ascertain your future with music and the associated audio equipment before marching towards the immaterial virtual music world.

Well a good friend of mine who hides in the shadows of the Bavarian landscape warned that no hard disk system could compete with the better CD transports, he is perfectly correct!

Tbg - I feel that investment in DAC and HDD is more secure now than in expensive CD or SACD player since server can play wider range of formats and is more flexible (plus internet radio). In addition it is easy to use - no CDs to change, playlists available, easy to find CD etc. Being not dependent on transport (that sometimes fails and is hard to fix/replace) is a plus as well.

There are still many top notch CDPs like latest Meridian with non-apodizing filtering or DCs Pucinni (I'm not going to spend $16k on Meridian).

I don't understand how HDD can sound different than SSD since both are synchronous devices with buffered outputs. Once data gets into computer there is no way of telling where it came from. People offer anti-vibration pods to place under external HDD claiming better sound. It might work under CDP since laser/media are not immune to vibration and data is asynchronous, but not in synchronously clocked data from HDD. Is this a placebo effect or something else was different during test (computer used, digital cable, Itunes versions, Itunes options etc.)

Kijanki, I have to retain a Blu-ray player as I have 400 sacds and want a quality blu-ray player, but I agree with you on convenience and greater accuracy of reading from memory rather than optical devices.

I must say that I got a Mac with SSD on the advice of some top people in digital, but got a HHD to serve as backup. I decided to do the comparison out of curiosity. I have heard others say that it is the lack of moving parts that is the SSD advantage.

I must say that curiosity also lead me to using cd mats on cds while ripping to hard drives. This on my other music server as the drive on the Mac, of course, will not allow a mat. The ripping speed using Exact Copy was about 40% faster than without and the sound was much preferable. I demonstrated this at the 2008 RMAF. While I ripped a second copy onto the harddrive most were saying that this was a waste of time. On hearing the improvement, I heard many saying that this was impossible, but most left to buy the mat that I was using, the Millennium.

I have much training in psychology dealing with selective perception I know it works both ways, namely that if you don't want to hear a difference you don't. Clearly those in the room at RMAF did not want to hear a difference. In neither the mat experiment nor the SSD vs. HDD was there any difference in the test other than what was experimentally introduced and I don't think there was any selective perception. At least even were there, I wouldn't care.

Tbg - I absolutely believe that CD ripped as data (EAC, MAX etc) can sound better than CDP in real time but there are things that people believe (placebo effect) or don't (negative placebo effect) that are simply crazy. Below is fragment of one of the serious professional reviews of Bel Canto S300 amplifier:

"My friend Rocky, a long-time fan of Bel Canto products, predicted that the S300’s rubbery feet caused the ills I heard -- soft bass, subtle veiling. It seemed logical that the "lossy" footers dissipated some of the tremendous energy of which the S300 is capable. We removed the feet and balanced the amplifier on three massive ebony cylinders called Shun Mook Diamond Resonators. The results defy logic. Upper bass expanded filling the room; midrange took on a spooky verisimilitude."

How do you like this reasoning - soft bass because of soft amplifier's feet? This is as stupid as it comes. Maybe feet should be hollow to make sound more "airy" or kept wet to make sound more liquid? (Shadorne is about to jump in - he loves this kind of things)

Kijanki, well, I firmly believe in trusting ones ears. I have heard too many instances where implausible things are audible.

In the case of an amplifier moving a wire within a magnetic field clearly can induce a signal that isn't the music. I would never use rubber feet under anything. Springs and like-pole magnets, in my experience, also muddy the music. I probably have fifteen different isolation devices here that don't work. Some of them, I must say, are preferred by others.

- what magnetic field? I hope you're not talking about earth's magnetic field.
