Hi, i have a question regarding the DAC MODE when used with an PC: Is it possible to connect the R3 to the PC via USB-C and then connect it via 2.5mm to an headphone amplifier with balanced inputs? (PC -> R3 -> balanced Headphone Amp)? That would be a very cheap way to get a balanced & portable...

My LC is still living on my desk and powers my AKG K712 just fine.   First i used the OPAs in this order:   BB2134 BB2132 LM4562   The 4562 was quite better, than the 21XX OPAs, but after 2 years he started to make noises and the channel balance was unstable. I recabled all wires and...

Quote from the website of the "superpower":   SPJ78, specify voltage [note that standard LM78xx can be used]... as also for SPJ79...   Moneyburner detected! You can easily DIY a really nice power supply for less!

Hi, i bought the M. Explorer for 150$ and made a A/B comparison with the HRT Music Streamer II i own. The Line-out sound is very close to the Music Streamer. In my opinion the Music Streamer is a little bit more forgiving and brings less details to the ears. That is as a matter of facts...

Hi, where did you connect the new PS? Have you removed all parts of the old one? Don't be shy and post some pic of your wiring.

New pictures for the thread!   I matched the transistors and resistors... seems like no deal after all. Sounds allmost like my first clone.      

  Once i had the same task. It was so annoying and after 9 pm i was filing underneath my blanket because it was so loud. Allways buy a case with a pre cut for the IEC connector!

  Well yes, the Sony is a beauty and has some nice specs. But that is not what i intended to say, because that is not a product for every wallet. When my cheap sansa clip+ for my flac libary got broken, i recognized that everybody is using their (mostly schlocky sounding) mobile phones, cheap...

Didn't read lol, because i have no temptation for A&K players. Well, a joke about a good competetive portable player from Sansa, Sony or Samsung would have been a bomb... :P

I've paid about 20$ for my Mundorf input capacitors (2,2uf)... but that is insane Looking forward to hear from your results.   By the way, i would like to buy a bigger amount of BD140/BD139 transistors from ST MICROELECTRONICS, so are the CDIL / Philips ones so much better?   Kind regards...

  Thank you, i ordered one 2min ago. I own a pretty nice multimeter for capacitors cap., but i was missing the hFE meassure method. The next clone will be way better, than my first. Maybe the DMM is worth the money, even if it is not super precisely like my 100$ UNI-T device.   I think...

I never found a reference for that 10.000uF 35V capacitors at the manufacturer. Maybe they are only for OEM or they are fakes. But sincerly, i've takin apart some larger amplifiers for speakers and the largest capacity i found, was 8200uF. Also keep in mind that the elko capacity can rise when...
