Accustic Arts

Tbg, I agree with both your points. I think that the AA combo needs to be compared with componets at the level of the P3/D3, and I also agree that consensus is unlikely, and ultimately a search for something not possible - defining the "the best" for all people and all ears. I simply feel the AA has to be in that circle of products that needs serious consideration when looking for great digital options. You then deal with issues of price, ergonomics, flexibilty, and look and feel. The Memory Player, and future products based on the MP technology do seem to be very promising, but I can't help but feeling it would be best to get a generation or two to pass in the product cycle and get other designers to think about the approach and optimize the execution and implementation of the technology.

Pubul57, I agree, of course. I do think, however, that there has been four or five years experience with hard drive sources for cpm. I can remember hearing a first VRS unit at a show in Silverdale Washington at least five years ago. It was awful. But as in everything involving computers, next year's products obsolete those of today.

I have not personally done an a/b. My best friend just sold his accustic arts combo (current models on the dac/transport combo) with stealth sextet cabling in order to buy the amr. He said it's the best cd player he has ever heard. I listened to his accustic arts combo and thought it was very good. I thought the build quality was excellent, but i didn't think it was worth the money. I swapped out my Meridian 808 in his system and thought the sound was as good, more dynamic from top to bottom, but i thought the accustic art combo was maybe ( I mean maybe) a tad bit more analog like. His amr player arrives any day so I will comment when I hear it.

Thanks Optarchie, that lends some context to your comments. I get the feeling that we are talking about several pieces of gear, all of which are first rate. I also suspect the preference for one over the other might be dependent on the rest of the system and its sound signature. If one little cable can make a "big" difference, I would think that the choice of pre/amp, cabling and speakers would have a large influence on wheter one would prefer on CD player over another in a given system context. I going to work hard to stop thinking in terms of best this or best that - I think it is much more realistic to think of a choice of top flight alternatives for a given component that on should consider, and that system matching and room acoustics also play a large role in assesing equipment. The AMR does seem interesting, especially at its price point. Thanks.

Can anyone talk in detail about of the function of the DAC1 mk4's 66 bit/1536 kHz upsampling and digital filter? What are the sampling options and is the filter linked to the upsampling? i.e. does the filter perform noise-shaping on the signal it has upsampled or is it an interpolation filter that can it be employed at lower sample rates as on my elgar+?
Has anyone compared it with 176.4 or 192kHz signals from other dacs?
