Hi all,   Anyone knows where to find spare filters and filter rings for E-Q7? I've recently exchanged filters of my E-Q7 and I have no more filter rings, so it would be impossible to replace filters any more without some spare rings and filters. Tried to contact local distributor (in my...

Does anyone have an experience with rapidrepair.com recently?   About 10 days ago I've ordered a 240G HDD for ipod 5.5 from rapidrepair.com, after 1-2 days they sent me an email saying that they need a copy of my photo id or my credit card. At that time I emailed a scan of my passport that...

Generally speaking I'm quite satisfied with Itunes and converted the whole of my CD library (which was ripped by EAC or MAX) into ALAC with Itunes. Recently I came to paly with some 24/96 files ripped from DVD-As or purchased at highdeftapetransfers.net. Originally I converted them into ALAC...

I couldn't find any specification which tells the output impedance of ipod's line out. Anyone heard or measured by yourself? (Mine is a Photo 60G.) Thank you in advance.

After spending all WIMA FKP2 caps I had, I'm considering these caps for Xfeeder curcuits. http://www.mouser.com/index.cfm?hand...oductid=286904 http://www.mouser.com/index.cfm?hand...oductid=293391 They are polypropylene, 1% caps. I know quality of these caps is critical, because these are...

After considerations about power supply for my (supposedly) portable amp, which is comprised of 2 AD823s, Ohman's Xfeed, and Jung's discreet buffer, I've tried to build the circuit of PPA battery board by Tangent. So I'd like to thank him first. It seems to work, at least it's possible to...

Maybe this is a replicated question, I apologize if so, It's well known that Tangent's META42 home page says that registers for the inner loop are to be higher than outer ones, and recommends R5 to be 5-10 times higher than R3. While in the PPA schematic, R5 = 3k and R3 = 1k, so it's 3 times...

Well, I tought it could be nice to use Gilmore's PSU with my opamp amp (using OPA637/HA5002) of META42 like topology. And I tried to build one. Separatedly, the PSU seems to work. Without load (e.g. leaving the sockets empty), it gives supposed voltage (+-15v) well while the chips put, voltage...

Dear Headfi DIYers, I've tried stacking six HA3-5033s per channel for my meta42 like amp, and sonically quite preferred it to my former 3 Buf634s per channel version. Unfortunately, running this amp for more than 30-60min, buffers start to malfunction. They stop all operation and only make a...
