Eastern Electric's new tube DAC using ESS Sabre??


anyone have it or have heard anything about it? any reviews?
im quite curious about it.. price is $750 and they use the ESS 9018 sabre dac

Mike, If you haven't used the same signal path, then it cannot be said definitively that the Hi-Rez through the Minimax is superior. One would have to feed the Hi-Rez files through the exact same pathway/equipment & cables to conclude that. That is why I used the same player/pathway to experiment.

In the article I do say:
This fairly makes “Hi Rez” downloads a moot feature. If Hi Rez streams at 24 bits, but one can take plain old streaming audio at 16 bits and get the same result, there’s not much incentive to pursue costly downloads. Alternatively, there’s a lot of incentive to gravitate toward music websites like Rhapsody, or one of my new favorites, Lastfm.com; the final outcome as treated by the Minimax is theoretically better than your typical Hi Rez sound! I say theoretically, as I have not actually compared Hi Rez files to those upgraded by the Minimax. However, there is no mistaking the upgrade to the sound of even a 24 bit signal from a Redbook player.

(Back to discussion) Two points: 1. My main contention is that the powerful upsampling and gorgeous result from the EE will so please most people, except for the hardest of hard-core audiophiles, that they simply won't care; they'll be quite content with the result from mere streaming audio versus paying for Hi-Rez downloads. 2. I do say "...theoretically", and "...if", so, if you say there's a big difference, I believe you. BUT, is your comment based on a tight test or another "theoretically"? :)

I'll see if I can't experiment. However, to run a true test I'd need an identical recording save for the bit/frequency, as well as a source which can accommodate both.

As to your struggling with the upsampling, the EE DAC is simply taking 24/192 upsampling to a new level. New info is being added when going from 16/44.1 to 24/192, and the Minimax is doing the same thing at a higher performance level. I had both Morningstar Audio and ESS Technology proof the article for technical corrections, so I'm fairly certain my analysis is good. :)
i have a reference recording 24/172 sampler and listened to one of the tracks, rachmaninoff symphonic dances, thru the minimax, mentioned in my review (audiophilia.com), which sounded stunnning, better than most other discs i have heard.

according to bill of morningstar audio, the dac will output 24/176.
Hi Doug, Thanks for the reply,

You are correct that I haven't been able to compare redbook vs. hi-rez directly, but I have heard many hi-rez sources and they certainly do things better than most any of my redbook sources, which clearly sound better than the lossy MP3s I listen to frequently (the Linn Jazz/Radio/Classical streams at 320 k sound very good). None of the 256 K or 128 K stations I frequent sound as good as the 320 Linns. (through Logitech Touch into EE dac)

IMHO I feel that you overstated the similarity of lossy MP3 vs. redbook vs. hi-rez sources.

Great dac though, that's for sure. I'd encourage you to seek out some true hi-rez material (there was a free download of Stravinsky's History of a Soldier (sorry if that's not a perfect translation) and it's superb).

As good as you think you've heard from the dac, I can assure you there's more to be had if you try some hi-rez material.

Thanks for the friendly banter!

Mike, I don't use MP3 as an audiophile source, and not testing it I wouldn't include it in my suggestion of the DAC's performance. I'm curious to test out our discussion going forward. Yes, good conversation.
Doug,

Why do you say "New info is being added when going from 16/44.1 to 24/192" when upsampling?

I absolutely disagree with that statement. That is not what happens when upsampling. It´s not impossible but it´s not what happens. If you wanted, you could write an algorithm to insert/create "average" information between 2 points but it wouldn´t be true to the original analog signal before it entered the first ADC. It would only be a guess of what probably might have happened.

You can´t "rescue" bits that aren´t there or that have been taken out.

Upsampling is about another thing. It´s not about having more information but, as I understand it, making it "easier" for the DAC to process.

Making a parallel between audio and visual, having a DAC accepting more bits is like having a LCD TV being able to reproduce more colours. And, having a DAC accepting a higher sample rate would be like a TV being able to receive a higher rate of frames per second. So, if you have a HD TV and feed it with a Bluray, you will be able to appreciate perfect visual definition. But, if you feed it with cable TV or even a conventional DVD, it will look worse, not the same as a Bluray! The processing in the HD TV might help to make it look better than in a common TV but it won´t look the same as a Bluray just because Bluray has lots more information.

I think the discussion is valuable but I wouldn´t like the thread to turn into a tech discussion and stay about the EE DAC. Much better to have comments about experiences listening to it!
