My good friend Raphael has put up plans for a few open source DIY MP3 players that seem like fun to build. He does sell kits or you can get the parts yourself. Pretty easy and straightforward, worth a look for all the DIY heads here! http://www.teuthis.com/html/kits.html

Apogee, an industry leader in A/D D/A for professional audio has announced a new portable DAC, the link is Here . sounds interesting!

I am planning on building a phono preamp/headphone amp combo for a friend who owns a record shop. He has numerous turntable 'stations' where customers can listen to vinyl before buying. At the moment he's got the little Radio Shack mini-stereo amps hooked up, but the pots on the unit just aren't...

Anybody try these tubes out? I just got a pair of Ei EL84EG tubes from www.tube-shop.com and so far I prefer them over the steel pin versions available at Triode. Originally I was using the JJ/Tesla EL84s in my MG Head OTL with great results (especially the bass), but these new Ei tubes seem to...

I have available three sets of AD8610 (x2) soldered into Brown Dog adapters for $20 each, shipping included. Please PM me if interested!

I really like the WBT 0147 connectors on my Silver Bullets 4.0 IC's. I plan on building my own silver interconnects using teflon coated 24ga pure silver wire, and was looking at the Vampire connectors. Has anyone used these?

I've seen a bunch of auctions on ebay for power conditioners made by Powervar which seem to be going for really cheap. Would a unit like these function in the same way as say a Monster power conditioner? Will these isolation transformers help reduce noise in my system?

I read somewhere here about replacing the electrolytic caps at the headphone OTL output jack with a film cap of 22uf. I'm using a pair of HD600's exclusively, so I want to do that mod. I checked Solen Fastcap, but a 22uf 630v cap is waay to big to fit in the MG Head. Would it be wise to go with...

I love my new MG Head, but 9 times out of 10 I'm setting the volume level between clicks. Where might I be able to find a high quality non-stepped 100k stereo pot to replace the stock one?
