Here is pisture of better universal PCB design easy to use axial or radial capacitors. (under the orange ones) https://cdn.head-fi.org/a/10239859_thumb.jpeg

What about to use on PCB universal pinout for both sizes of pots, like is in PIMETA v2 ? For small and big one (Blue Velvet) ... https://tangentsoft.net/audio/pimeta2/bitmaps/brd-2.01.png And for capacitors use "two holes" for possibillity to use more sizes? It has Millet MiniMax and is it...

Just arrived Samson QH4. Horrible quality! -Pots are scratching -Left channel has bigger volume -setting volume is very difficult because there are Master Por and local out pot. Combination of both has influence to distortion of sound. Master pot can distort sound. Sound is normal. Not bad...

Nobody answered :-( I am courious too.

It plays from Wifi and streaming?! Has Bluetooth support for AAC codec from Apple devices ? (not just Apt X)

Strange is, how it will be implemented. Dirac is optimization for headphones. How it will sound on speakers thru line out... And what about balanced out ? Headphone amp is balanced :-)

Now they change backplate? It seems it is it still not in final stage. I hoped this product will sell next month :frowning2:

I tested sound between "original Apple Lightning-Jack dongle" and jack in Ipad Pro 10.5". Sound of jack is much much better and louder. Dongle has sound softer without impact :-( The way for me will be use bluetooth headphones. Or to use Bluetooth receiver for wired headphones...

Bravo. I should do it the same way :-( Plastic unshielded box is the shame...

I love listening headphones, I am thinking these are the right way to heaven. I tried them on Audio Video Show Prague very short time and I fell in love.

I have my too. I am just start buildind. Still wait for some devices from Mouser...

Thank You for answers. Now I can imagine more about this product. Is sad, that there isnt analog input too. With it will be easy applicable iDSD Pro as preamplifer to power amp. (I have power amp with balanced inputs.) What type of headphone amp sound similar to iCAN Pro do You mean? iCAN Pro...

A-Will be symetric XLR output at back side volume controlled ? (To be possible connect it directly to power amp)   B-Is there analog asymetric RCA input for using PRO as headphone amp only ? (as is on iDSD Micro 3,5mm Jack)   C-Could You writte more about headphone amp sound signature ? I...

So they should make battery powered iCAN BL in black case!

My iDSD Micro (old) it makes. Other headphone amps usuallyhave delayed output relay to prevent it.

Does BL still make big "Cracking sound" in headphones after power on ?   Isnt any info about iCAN SE in black colour too ?

Isnt needed any DSP processor or something to control this DAC ?

I am looking forward when will first member hear it. Will be separate thread here ?   EDIT: Here http://www.head-fi.org/t/831737/audio-gd-singularity-19#post_13158209

What about relay attenuator ?

I found the same construction philosophy headphone amp http://www.6moons.com/audioreviews/yamamoto4/ha02.html   I dont know its sound. I just foud it on web... Ilike using C-core power tranformer. Dont it make possible shorter construction ?

Now is new firmware for A100 II and AK120 II. http://hosted-p0.vresp.com/1025497/5c9253db20/ARCHIVE Newest Version: 1.28 1. AK CD-RIPPER support 2. Added CUE sheet support 3. Better firmware stability   BUT NOT for AK100 !   I hope will be developed for classic AK100 later! Need...

I have iDSD Micro with Sennheiser HD800. I love this combination. ODAC was not good for HD800. There is possible to buy cheaper version iDSD Nano with the same DAC. Maybe is this way for You...

Solved: I bought new tubes and scratching is gone.

When I insert capacitor after pot, so is problem gone. But is it another capacitor in signal way.
