post #1 of 21
Thread Starter 

All information: http://www.totaldac.com

 

Semi DIY DAC, available fully built at EUR 3850

 

Discrete components DAC: R2R DAC with 0.01% Vishay foil resistors

Clock and anti-jitter FIFO: it uses a buffer memory (FIFO) to store about 10ms of audio data at the digital source rhythm and output a stream at a local oscillator rhythm.

Active crossover configuration possible.

Created his own R2R from scratch.  NOS.  Jitter rejection from all sources.  Sounds promising.  Would love to hear it.

Considering a Berkeley Alpha costs about as much, that is seriously tempting in that budget range.

IMHO, its biggest weakness is the lack of connectivity, although it could be remedied if you can DIY.

On the other hand, considering it s price of parts/ price of finished product is outstanding.

Looks amazing, way out of my price range though!

And of course balanced outputs would be nice.

That is one sexy DAC!  All those z-foils are giving me wood.  The $5500 is bringing be back to reality

I have had the chance to listen to this dac and can safely say it's the best dac I've ever experienced. That sounds like a cliché but I was indeed blown away by this dac. It's got a headphone output as well and with my LCD-2 connected straight the totaldac's out I was convinced this was even the best amp I have ever heard with the LCD-2! Note that I'm a huge tube fan and here comes this dac with a ss headphone out and trashes every dac/amp combination I've heard to date.

 

I'm really loving my LCD-2 rev.1  but I have always thought they were just a tiny bit recessed in the treble department. Not so out of the totaldac. They were spot on. Not lacking ANYTHING at all. You'd be hardpressed to find a headphone/amp combo in any pricerange with a lesser dac that could match this. I also heard the totaldac with a Sennheiser HE60/STAX SRM007t combo. Listening to Chabrier's Espana on Mercury Living Presence made me turn my head to see who was playing the tambourine. This was a mechanical reproduction of music that sounded the way it ought to sound: effortless and natural with such ease. Made all other dacs sound like they are struggling

 

Since hearing the totaldac I've been trying to to figure out how to afford one. I came as close as to order one but alas a change in my financial situation commanded me to cancel it confused_face.gif. But I wish any future buyers many happy hours with a supreme musical experience (and a little bit of envy on my part).

Comparison against the Invicta and Cantata would be fantastic. 

 

I do have to say it's an ugly clunky looking box.

Agree on both parts. The Cantata is still the best digital source I've heard.

The new one is significantly better on the eyes, but not on the wallet, except in comparison to what it supposedly beats.

It shouldn't be hard to beat the PWD at that price...

 

EDIT: First birthday post!

You read the 6moons article? Comparing against 20k euro pieces at a cost of 6.5k. To their ears at least.

Hmm. No 'Blue Moon Award' though?

Now these two dacs are both using standard converter chips. The totaldac is a discrete r2r ladder design not utilizing a converter chip but resistors. If you haven't heard a r2r ladder dac you're in for a surprise. It's a whole different ballgame.
