I'm interested in this DAC... Is there some 'guide' to modify? This thread is too huge to read...

Hi folks, I found some results of RMAA Test for Audi-gd DAC-19MK3 and Reference 1 on Japanese forum. Quote: DAC-19MK3 Reference 1 DAC-19mk3 Frequency response (from 40 Hz to 15 kHz), dB +0.11, -0.91 Average Noise level, dB (A) -87.3 Good Dynamic range, dB (A) 90.2 Very...

I'm looking for DIY DAC for my desktop. AlienDAC and AMB gamma-1 seems to be good but I concern about their compactness because I don't need portability for the new DAC but sound quality. Buffalo DAC has right size but it's a bit expensive (my budget is 200-350USD). Does anyone know any other...

I heard some people used 2 single-ended amps as 1 balanced amp... Does anyone know how to do that?

Can I replace 4 silmic caps to jumper lines? According to the datasheet of AD1852, there are no considerable DC offset from AD1852's analog output...

Hi, Let me ask about LOD for iMod. What caps or registors should I use for it? I read the datasheet of Wolfson's DAC and it said there should be 1uF cap and 100 Ohm registor between DAC chip and external amp. But I didn't hear about registors for LOD for iMod... so now confused.

This is one of the most interested topic for many people today, I think... Triple.fi 10 Pro vs Westone 3... Anyone has thought about this?

I'm thikning about modding my K701 to add K702's "detachable cable" function. But I don't know well about these mod. Are there some guides about it or more general headhphone recabling?

Hi, I'm interested in this can. Where is the best shop for K702's price today?

Does anyone know what the blue small boxes that are next to the DAC op-amp are?

Does anyone know where ZERO's I/V converter circuit is?

Thanks for your great guide, PP. Let me ask questions; 1) Why should I cover the PIO caps with shrink wrap? 2) Can I use film caps instead of the PIO caps?

I got my HDAM today (thanks for Currawong's great guide). Then I soldered the earth wire of HDAM to the RCA ground and snipped the unnecessary capacitors off - much better sound than I expected! Btw, are there any other basic (easy) mods?

Hi. I'm thinking about recabling my K701. I know one of the best ways to recable is Moon Audio's Black Dragon. Are there other recommended recent recables? I feel Black Dragon is a little expensive... Syu

I found another headphone amp from audio-gd.com...$225. н¨ÍøÒ³ 3 Does anyone know about this?

Wow, there are various attractive amps in this price range! Little Dot MK V - $289 Shanlong PH100 - $218 Head-Direct EF1 - $399 audio-gd C-2C - $330 (according to Currawong) AV123 X-head - $199 Graham Slee Novo - $345.7 And some tube amps (e.g. Darkvoice 336SE - $229, Darkvoice 332 -...

Let me ask some questions. 1) When I use ZERO only as DAC, the only working OPAMP is DAC OPAMP, right? 2) If I use ZERO only as DAC, volume pot upgrade is meaningless, right? Thanks.
