I just got one IDAP-6 and I have a few problems: - I cannot use the 2 back USB-A to connect my Toshiba USB drive? - When I use the front USB, the Cayin does not see the disk 1 time for every 3 bootstrap? Any Idea?

The Denafrips Ares R2R DAC is very good for the price (around $650).

You might want to consider Denafrips Ares, excellent value for the price IMHO It is a R2R DAC like the DAC-19, NOS-19 or singularity 19

HD 600/650 is a common choice. It is easy to unplug the stock cable and replace it by a 4 pins XLR balanced cable. You find some decent china made under $100

Hello,   I am in the situation you describe... HD-800S, Liquid Carbon and FIIO X7 as source.  The X7 is pretty good but... I feel that the setup deserves a better DAC. I'm pretty much sold on R2R but is the Bimby enough I should I go for bigger? 

It is more something that I don't hear than the contrary. Something that triggers emotion. I can't  put a name on it. I  remember getting that with my old Marantz SA-11S1 which is broken since quite some time. Perhaps I should fund the expensive repair? Or is it my upgraditis trying to justify...

I'm using X7 FW2,0 as a DAC, amplified by Liquid Carbon to H800S balanced.   It sounds good, VERY good. Running HD800S balanced is a must, it improved dynamism and precision. More holographic sound stage!  You get this already with an AM3  and LC improved everything. On the minus side, the...

Sorry if the question has already been answered.   What is the resolution of this DAC in bits, compared to Bimby 16 bits, Gumby 18 bits and Yggy 21 bits?

With HD 650, theAM3  difference between SE and balanced is stunning. Double power and increased grab on the drivers might be the explanation.

  Refornat the SD card in exFAT. It corrected this problem for me

Hello,   Is it possible to use the X7 as a transport only to  feed another DAC via the USB out? I know this is possible  through the Coax out.   Cheers

Still no Switzerland in the 50% auction?

  I use the same sdCard and same firmware,   I have the same problem at startup  

It is available in Europe or at least in Switzerland. My preferred reseller has one in stock. To buy or not to buy...

I wonder if the DAC part of it is also balanced? Which is the same as asking if the PCM1792A is a 4 channels or 2 channels? This amp is very interesting and not expensive if it is a real and full balanced dac/amp.   Anybody?

@FiiO-Shadow  Do you know if Switzerland will be added to the promotion list for 50% discount on amp modules for the X7?

Hello Fiio,   The K5 has a balanced line out which implies that balanced lines are coming from the docked DAP to the K5. It would be marvellous if you could make a balanced amp dock based on the K5/AM3 technology with a headphone 2.5mm TRRS output? Add an XLR input and combined with the X7...

A balanced 2.5mm TRRS cable for HD650 would make sense

Hello,   This dock is very nice, there is just a problem with it: How do dock the X7 and hear music through the headphones when  docked? That would be a nice feature to have a docking station leaving some space at the bottom to free the access to the head phone plugs?   Cheeres,   Alain

Hello,   Could you add Switzerland to the promotion list.  Only X7 with AM1 are available and I'd  like to get the AM3.   Thanks,

3.7 cm, measured! You might buy some from Jan Meier.

Very interesting! I'm planning to start with the Tfk ECC801s at the center and Tfk E88CC on the sides. Then swap the center for: 1) Sylvania 12at7 gold 2) Mullard 6201 and see what I prefer. These two should add a touch of warmth to the neutral Tfk E88CC. What do you think?
