Default Altman Attraction DAC. Ulas, Poobah, rfblw, Guido, anyone?

Can anyone explain to me what makes this DAC so revolutionary, at least according to it's designer/seller? I'm still not sure what is so special about JISCO? There was a thread about this DAC on this board, but no one really got into the technical details of this DAC. Ulas, dare I ask your thoughts on this DAC? Maybe Poobah or rfblw can chip in?

Re JISCO try this.
As for the dac, it uses the TDA1543, a chip I dislike intensely, so any comment will be biased. So here is a probably more objective comment.

Actually, DUC985's opinion/preference is subjective. So is yours. Mine too.

I wonder if he used a dedicated PS or Charles' recommended battery power. Makes alot of difference with the Attraction.

Now that's a fact, IMHO.

FWIW,

In so far as he is prepared to contemplate listening to the TDA1543, compared to me he is objective.

I wouldn't care to comment beyond that I saw that site awhile back... the guy's not just whacko... but angry too... cones can ONLY be PAPER etc... dead giveaway.




Edit: I looked at the TDA1543... the minimum SNR is published at 90 dB... which really implies 15 bit performance. Looks like another mythical magical chip to me.

I've never heard one, I do not know the price either so can't judge on performance. It seems they take care of jitter, allthough I do not know the performance of the clocks they use, nor do I see extensive (low noise) power supplies. The TDA1543 in my ears (and measurements) is not the best choice for acurate and high resolution playback.

LOL!

Considering that Guido could not deliver a XO2 and XO Supply that measurably met his own published specs to me in over 2 months of multiple back and forth shipping, and eventually ripping me off of $221.00 by giving up and refusing me a refund, I find these comments from Guido laughable.

And those *are* facts. Guido/Tentlabs is a ripoff.

Guido. I would still like to return the unmounted unworking kludge you sold me for a refund. Nothing more.

Care to own up, or are you as usual blowing wind?

Steve, if you've got a complaint with Guido, that's not an excuse to hijack a thread. Take it to email or start your own thread, following the no-abuse guidelines.

After 2 errors from my side, and some back and forth shipments, the modules in your hands meet the specs and function well.
