After a bit of research, and realizing that this was probably in the wrong category (sorry for this), I think I ll try the squeezebox touch

Ok, so, I'm not even sure that whole thing is possible, but I  was thinking.   Right now, whenever I want to listen to music on my speaker setup, I have to switch the computer on. Switch the external hard drive on. Plugin my sound card. Wait for windows to load. Etc, etc... And there are...

Since there s already an opened thread, I thought I'd post in here, since I'm also considering the idea of building a loudspeakers amp (I'm asking the question here,@ headfi because, I've found that the community was great, I've already built an alienDAC and a PPaV2 with the advices of the...

Thanks to all of you for your answers. Gonna buy eye/ears protection soon and will try taping the shaft

Hey guys, I ve got 2 little questions regarding casework. First : the one that boggles me more I have an rk27 and this volume knob : 45KN031 I ve tried attaching the knob to the pot using the small screw that is inside the knob, but the result doesnt feel too good. The knob simply...

Hopefully last update : I've biased the amp in class A, swapped opamps around a bit. Impressions : Full opa627 : good ad 825 : unimpressed opa627 on G, 637 on L/R : WOW!!! After trying the 627/637 combo, I was sold. Sound is detailed and has enough "punch" to satisfy me. I still...

I was using neutrik nys rca jacks for input, and hadnt taken the time to properly screw the ring that connected ground. It didn't made contact most of the time with the jack, so my input ground wasnt ok ^^ yup, I feel a bit ashamed ^^ I'm definitely going to try opamps other than the 627...

It's alive! I tried it with my Senn hd650, after double checking a few things and it delivers!!! now, to bias it into class A ; try different opamps ^^ and case it thanks a lot for your help guys, Tangent for all his advices, info and espressogeek for keeping me motivated ^^

I've worked a bit on my PPA today, to try fixing it, here's what I've done : 1/ I've realized I had forgotten to jumper S2R! doh! fixed it! 2/ I realized that last week, I had changed the output resistors (from 2.2R to 4.7R) but hadnt touched the output buffer trim pots. So voltage was a...

I ve measured the ouput, unloaded voltage of my AC adapter and get 26VAC. According to the ps parameter estimator, that means the reg will get pretty hot. I've raised the output voltage of the TREAD to 27V for future tests. If it still gets too hot, I'll consider changing the heatsink for a...

Well, I had already used the power supply parameter estimator anyway, I'm using a TREAD kit, so the cap is 680uF the power supply is rated for 24VAC, with 35% reg, which brings us to 32.4V unloaded. Rated current is 0.5 I live in France, line frequency = 50Hz. I'm using a standard...

Mmmm I officially don't understand what's going on. First, I've added the heatsink to the TREAD, and I've changed the output resistors to 4.7r (from 2.2) then I've tried measuring the current flowing to the PPA. However my meter is ****ty : caliber is either 10A, or 200mA and lower...

The kit is 88.92 but it includes an adapter pack which you cant use since you live in France, so it will probably cost less, you can add 40 for the custom panels but it's not mandatory, and some more for the shipping Le kit est a 88.92 dollars mais comprend un adaptateur secteur que tu ne...

I can confirm that Jeff ships to France. I ordered an Alien DAC kit before from him and received it without any issue
