I powered up my sigma 22 for the first time and the V- rail is outputting 4.2V while my V+ rail is correct with 29.2V.  (I am going for +- 30V).  I have troubleshooted everything and my negative values are very close to the R2 to ground, Q5 to ground, and Q5 & Q6 to ground readings (on the...

I stupidly forgot to note what the ground terminal is and what signal is before I desoldered the original cable.  I left the original red and white cables attached to the driver.  Can some one tell me which one is signal and which one is ground?  Or, does it even matter?   Thanks, Mat

I have tried searching through some threads already and could not find my answer.  I might be over thinking things as well, but is it okay to twist different gauge wires together?   I am building a B22 with a E22 backplane and I noticed on some pics that the V+/G/V- and output pad for each...

I'm thinking about getting some custom mold earplugs for concerts. I'm also a musician so they'd be used while I play as well. I wanted to know if there were some recommendations that people have. I've looked into the Etymotic universal fit, but I can never get a seal with flange style plugs...

I apologize if this has been covered before, but I couldn't find a thread with this info. I am planning a 3 board beta 22 build and ordering it from AMB Labs Kits - Glass Jar Audio. What gain should I get if I am planning on using this with Denon D2000? (One of the boards has to be active...

I just finished my SSMH and I love it, but my Denon D2000 are so sensitive that the pot only turns a few degrees and it is at my listening volume. The problem I have is that the sound in my HP are faded to my right ear. When I turn the pot more the problem goes away, also this isn't an issue...

I originally imported all my cds to AIFF on my MBP because I read somewhere that ALAC is still relatively new compared to AIFF and may potentially "die out" as a recognized codec. I have the hard drive space to store all my albums in AIFF, but I am planning on backing it my music up on my...

Ten minutes ago I was enjoying one of the better listening sessions I've had since arriving at college. The lights were off, no sounds could be heard, prime conditions for a musical journey. Fifteen minutes into one of my favorite albums, STS9 `Artifact`, and the roomy barges in laughing, flips...

I'm placing an order in Amazon soon and lately I've been in the mood for some Avant-Garde music, both classical and jazz. If anyone has any recommendations that are well recorded and at a reasonable price that would be great. Also, for the jazz rec, I kinda want to steer clear of the well...

Hello. I'm off to college next year and am in the search for a computer, but I haven't yet decided on getting a desktop or laptop. I originally had my mind set on getting a iMac (by the way, I would prefer a Mac), but Apple's new line of Macbook Pro's is swayin me a little. I don't know if...

I was thinking about making my own crossfeed filter based off the basic Jan Meier design. http://www.rock-grotto.co.uk/x-feed.htm# But since I'm new here, I'm not really sure if it would make a difference to my CD setup. I have a headroom total bithead amp that I use with my comp and ipod...
