CHORD ELECTRONICS DAVE

[ted_b]

   
Class D power amp?

Nope, but I can't say any more.  You're close though. 

 

[Beolab]

I think the Chord maybe have designed a new amp classification like a hybrid btw Class D and Class A-B and can be controlled by DAVEś new special digital outputs, where the D/A conversation happends after the amplification for a more exakt amplification in the digital domain. So i think DAVE acts as a Word Clock and signal source for the amps, thats why its to outlets.

But its just speculation

Are we closer to the target JaZZ ?

I have no further idea, I give up. Mysteries are fun, too.

My main concern about the Dave compared to Hugo is that it has an internal switching power supply. Compared to the Hugo which is battery powered or with an external supply, it might introduce EM noise... as opposed to an isolated battery which is what I think made the Hugo such a success.

An external PSU will have been a good thing. NO risk of EM noise and...even Allowing for (big)battery operation if needed.

Chord knows how to make a proper SMPS very well so that noise should not be an issue. Other high end companies like Jeff Rowland also make use of SMPSs of their own design and they are not noisy by any means. A properly designed SMPS can outperform a conventional linear supply, and should not be categorized together with cheaply made SMPSs.

Dave has such a wide OP level and ultra low noise, the gain of the power amp is unimportant.

Dave is SE as that's the best for SQ; but to do so is much harder, as differential gives measured benefits that hides SQ problems. Going SE means that you no longer hide the problems.

Rob, I have a Hugo which is wonderful driving active ATCs. I made up some suitable phono to XLR cables. I am thinking of upgrading to a Hugo TT, one of the reasons being the balanced outs on the TT. Are you are saying that I should still drive my ATCs from the phono outs of the TT rather than the balanced outs?

 

[JaZZ]

According to Rob Watts (posted in the «Hugo» thread) Chord has managed to maintain the same noise-free power supply as from the Hugo's and TT's battery – and the 2Cute seems to prove that. I absolutely trust Rob on this – he's a perfectionist with excellent hearing, not just a data fetishist.

Is it ATC SCM50 SLA or what ATC do you use?

I think the new digital amp will have a pulse array dac, but will take the output of the filter in DAVE
 
The pulse array dac isn't probaby that expensive, it is the FPGA that is the key element of the DAVE.

Something like that.. Smart use of the FPGA filtering in the DAVE, and just extend the internal signal path to an external amp and achieve a perfect transport without any loss and make the final conversion in the AMP, thats clever.

Rob, I have a question on Dave.
Can we still see the inside through the glass window? or the window is now an LCD screen and we can no longer see the inside?
I like the way Chord designs its products ... the users can see the inside and the LED lights on the boards and wondering if we can still do the same with Dave.

I can say to 99.9999999% unfortunately not, because of the LED or OLED display that CHORD will be using are most likley not a transparent display version, but even if it was, you could not see clearly true it, its going to blur out the chipset board.

 

[JaZZ]

Sad, but true. The round display reminding of a porthole has its own charm, though.

I think it loks like a breitling watch with the chromed HDSD ring. Feels realy expensiv.

I have alredy placed my order on the DAVE.
