Hi,   So,   I decided to go serious about music on the go. I have Hi-End CD player and amps at home, with some serious headphone amps made myself, driving Grado SR-325i.   Now I chase the dragon for some time, dreaming of my sony DD Quartz walkman of old, but decided that the time...

Hi,   I would like to know if there are earphones or IEMs that would have a sonic signature close to the Grados. I mean deep and clean bass, not boomy or inyerface, detailed highs, with real space and depth, round sound, entertaining :-).   Thanks for your suggestions,   Best

Hi,   I'm searching a very good portable source. I need a lot of place (64Go would do :-) ) and the best SQ possible. Battery time is also into consideration. Picture/video/game is surely not needed. At the mo, I use a Sony MDR-E818, which is not bad, but reminds me sadly my last MDR-E575...

Hi,   I'm searching a Walkman Sony WM-DD9. A WM-DD33 is also interesting if you have that.   Many thanks,   Greg

Hello, I'm in the process of creating my own Linkwitz modified crossfeed with relays for bias and high/low settings, in order to avoid long wires with signals between pcb and multipoles switch (usually in front). the solution is not in putting the pcb near the front, RCA are usually, at the...

Someone tried of these? http://home.swipnet.se/~w-50719/hifi/qrv08/index.html Maybe it has been discussed a lot here, don't fire me if it's the case, redirect me to where I can have some advices about these. The level seems very good. All the best, GregVDS

Hi, I just would like to know if someone has already done, or even heard about a headphone amp based on class-D or class-T technology (Tripath and alike). There are some kits outhere, but mainly for integrated power amp (2x15W to 8x100W, though THD not the best at highest power!)...

Hello, I made a STEPS (TangentSoft) power supply unit for my M³ (Morsel, AMB). It is tuned to give a little bit more than 24V. Everything works perfectly. In comparison to my homemade modified Cmoy, this is a pleasure to use and listen to. But the very high audio quality of the amp and...

Can you point me to feet, cones, or any other idea to put feet under the PSU and AMP boxes? Thanks to all in advance, All the best, GregVDS

Hi, I would like some help on designing a small complementary board that could be used either to simply switch between a number of entry, or switch between the different choices of the modified Linkwitz crossfeed pcb from Tangentsoft. Rather than using two dual two position switch, or a...
