nice work!! they better be all done, certainly no room for anything else in there
what value R are you using for HiC?? I have some buf634 on the way to try out too, glad you posted re the flatness without HiC mode or I would have been left scratching my head after all the praise they get on here.
and hey, what was Ron on about?? I thought he said single channel buffers wont work?? or I guess he was referring to one per channel. I thought that was odd when he mentioned that.

I think he mean single channel opamp won't work without those adaptor. There is still alot of room on top of the mini jack socket if there is ever a need to use
I'm using 200ohm. Quite a pita to solder it in. Actually it sound fine in normal mode. But the texture and smoothest Hi-C mode bring is really a bonus. It just make normal mode sound flat in comparison. thinking of using 100ohm. But will decide after the battery test. 200ohm should be the best compromise between battery life and sound at a glance
Yesterday had it running for 7h with my half drain battery. My iriver h140 went from 100% to 50% during this period. Seems good imo... I have only clock 4h from the recharge till now and it seems going strong. D10 MAXXED really sound like portable amps that cost alot more.
"Dear Sir,
Thank you for your email.
Did you try AD8656 with bypassed buffer? You may also get the TLE2426 with EL8201 buffer, which is warm and sweat.
Sincerely

...an annoying question for sure given all these posts but where and how do I order a TopKit?
After listening to the D10 for these last three months it has a pronounced high end lift. I've been listening to audio/high end for 40+ years (yes, I'm an old guy for sure) and can hear the sonic differences easily. The D10 has a problem and it seems that it has been glossed over by many posts extolling it's virtues. It just can't be me and a few others????

One way is to send HiFlight a PM, requesting to obtain from him a TopKit for the D10. In his reply, he will let you know how to go about it. If you take a look at his FS/FT Forum feedback, you will see that the transaction will be a good experience. I started using TopKits offered by HiFlight for the D10 within a few weeks of owning a D10, which is one reason why I did not notice much or post much about the sonic qualities of the amp with its stock opamps.

IMO, the AD8616 sounds better than the AD8656 when used with bypassed buffers. YMMV!
Hello, I have a question about my D10 and foobar2000/windows setting.
I currently have WASAPI optical output from foobar to the D10, 24 Bit output in Foobar, and 24/96000 output set in the Windows playback devices menu for S/PDIF. I am upsampling with the Sox plugin to 96000 and play 24/96000 vinyl rips (which seem to pass through without Sox touching them).
Am I missing anything here, or is this set up properly to take full advantage of the D10 being fed optical FLAC through foobar?
I don't hear to much from the upsample, but it doesn't seem to detract from the sound. Should I turn on anti-aliasing or adjust the bandwidth?
Just an update, my h140 just went dead after 11h of continuous feeding of optical signal in my d10 maxxed. the d10 maxxed is still going strong and it out live my h140 so i can conclude buf634 Hi-C in d10 is very usable

Very interesting. I would not of thought it so. And that is with 2 634's in Hi-C with a 200 ohm resistor per channel? Very nice.

Many thanks in advance!
If you have 24/96 rips and want to output 24/96 then it is nothing to upsample for the plugin isn't it?

100 ohm Hi-C shunt draws about 15ma/634. Using the stacked 2X buffers, there would be a total current draw of about 60ma for the buffers alone. Will be interesting to see the battery life with that configuration vs SQ.

yes. I believe 200ohm is a good balance between battery life and sq. But as we believe buf634 battery drain is too much for d10 battery to handle, it now proven otherwise. so nothing can be sure till we test them out. the maxxed kit is really wonderful sound. very powerful
Theory_87 - looks very cool. Which adapters did you use: the regular pins or the extended pins? It looks like the Buf634's are on extended pins and the opa1611 on regular pins. Is this correct?

Good imagining, soundstaging, headroom and extension. Did I mention excellent details and non fatigue after long period of listening? :thumbup: AD744obca topkit and tle2141 topkit sound pale in comparison. BTW, my opa1611CA sound distorted and low in volume. Anyone have that problem? It may also be due to problem with my browndog adaptor. Will revisit my opa1611ca at a later if when I order more browndog adaptor. I'll refer opa1611 *2 and buf634 Hi-C *4 as MAXXED kit from now on.
Can't really detect much different between opa1611 and opa211 using buf634. The different is more obvious with ad8616 as buffer where opa1611 sound airer and smoother treble compare to opa211.
buf634 sound flat and lack of texture. But put into Hi-C configuration, the bass goes deep with very nice texture.
Those resistor is a pita to soldier on
Have it running for a few hours with my half drain battery and everything seems good. The output volume is much higher than any opamp combo I ever tried
Waiting for my by-pass capacitors to arrive before call it an end.
