nice work mate, really good job, love the power switch on top like that, did you use anything to give additional diffusion the light from the LED? are those feet from audiophonics? been considering getting a chassis from there because they have cool feets of all sorts, plus mundorf caps and a few other bits and pieces so I can take advantage of the pricey shipping, which is better than the shipping directly from HIFI2000 anyway.

An RCA switch that switches ground as well, since my PS3 introduces some noise into my system.

EHHA Rev A (MOSFET):
 

 

 

 
Thanks to Horio for the idea to back-mount the neutriks. I really like the clean look.
 
Details and more pictures on the main EHHA Rev A thread....

Nicely done JDK, I have not followed the progress of the revised EHHA , but this tells me that it has come a looong way and looking fantastic too. Love the port hole windows and the overall clean build. I trust it sounds as good as it looks ..dB

Finally got time to put my DAC together. Took a lot of time but I'm quite satisfied with the result.

nice, I have the same dac( well, i have V1) 
 
some mods that make a night and day difference...
 
1) Get rid of the inductors and use the filterless schematic, this cleans things up and adds a little more sparkle. 
 
2) Ditch the anode load resistors, use a CSS (dn2450 cascode + heatsinks)
 
3) led bias the cathodes, elimating the electrolytic caps and resistors

 

[Lil' Knight]

I did try your 1) and 3) mods but felt the bass is not really adequate. Bumping the cathode caps does help this. I'll try the 2) when I finish the casework for my B22

 

[adamus]

Yes it was more bassy with the normal cathode scheme, but its too loose and wolly and artifically bumps it in my opinion and gets a bit 'one note'. CSS + LED is a lovely synergy.
 
You got me wondering about the bass, and its raining so i had a play.
 
I was abit lazy when doing the mods and only cut out the anode loads from one end, so reverting back was a two minute job.
 
anode resistors + bypassed cathode resistor = warm and tubey, loose bass, big mids, rolled off highs.
 
anode reistors + led bias = better top end, much ore sparkle, colder mids, tighter (some would say less) bass
 
CSS + LED = superb top end (silky smooth, yet good detail), mids are fuller but not overly bloomed, bass is big yet taught.
 
Its no contest, the CSS and LED are head and shoulders above the other combos. only issue is dropping the B+ as you just dont need the headroom with the CSS. I just stuck a big heatsink on the dn2450's as they will be dissapating 5 watts each.
 
one more note, with the inductor circuit in, the highs are rolling off into the audible range.

Thanks for the kind words. IMHO, it sounds better than it looks!

Hey Lil Knight that case rocks. Did you fab it yourself?

X2. That's a beautiful case!

 

[Lil' Knight]

The case is custom built by my local builder. It's great to have someone around to tell exactly what I need. The front panel is 10mm brushed acrylic.
I also have a matched one for my B22.

Very nice, duders.

Beautiful, can't wait to see some pics of the completed B22!
