Hi there, I am looking for en experienced DIYer to build me a modified Linkwitz/Chu Moy crossfeed from the kit sold by tangentsoft and house it into a small and portable case with proper connectors (in and out minijack) and selectors (bypass and mode). It will be used in a compact portable...

I experimented with a DIY notch filter for flattening the frequency response of the Etymotic ER4S, buitl according to Linkwitz's specs with this general schematics. I tried it at the output of several single ended headamps with excellent results. Now I have built a similar notch filter for...

I would much appreciate recommendations for building a Cmoy for portable use, powered by a single 9V battery. Main features are the following: - Based on Chu Moy's original design with no input coupling caps and no output resistors. - OPA 2227 as preferred opamp (socketed, though, and...

Has anyone tried the APS V3 replacement cable (hardwired) for the K1000? How does it compare to the Equinox hardwired? Is there any current consensus about the best hardwired cable for the K1000?

Is the a205A MkII a good option for driving the K1000? Since the Almarro has switchable 8 and 16 Ohm outs, can I connect the 120 Ohm K1000 directly to the speaker binding posts or do I need parallel resistors or even external transformers to match the impedance ?

Has anyone compared the ER4S with stock cable vs ER4S with APS recabling? Please notice that I am asking for the S, not the P. Does the improvement justify the investment? Looking at other threads it looked like the ER4P benefits more form the recabling. Thanks.

A question for all Edition 9 users/owners: Honestly, is the E9 really worth its high price? Please take into account that retail price in Europe is Euro 1500 (approx $2250)! Unbelievable: a product made in Europe is cheaper in the US!

What good closed cans would you recommend for listening to classical on the go with a decent source (iMod + portable V-cap dock)?

Has anyone recently done a serious comparison between the iPod classic with LOD and the 5.5G iMod with ALO black gate LOD using an external amp?

My research goes on and my main candidates are the following (I'll add some comments about the info I've got so far): Signature 30.2: very good reviews with the K1000. SLA batteries need maintenance, it is not suitable for regular phones. Cary CAD300SEI: very nice product, relatively...

Can a Singlepower PPX3 Slam drive the K1000?

I would appreciate recommendations for SET amps for driving the K1000. How about a 300B SET? Thanks.

Is the KGSS a good option for the OmegaII? Is it a real step-up over the top Stax amps?

What can be considered the electrostatic (non-Stax) amp with the best price/performance ratio for driving the Stax Omega? Anyone here experience with the Wooaudio GES, Rudistor Egmont or Gilmore KGSS? They are all reasonably priced in Stax terms.

Can a Singlepower MPX3 drive the K1000 with authority and enough headroom? Is there a headphone amp, other than the RKVII, that can work fine with both "standard" headphones and the K1000? Thanks.

Can someone please explain how I can measure the input impedance of a headphone amp? Thanks.

Does anyone know the input impedance of the Supermicro IV? Thanks

Is anyone there (other than Skylab) who has used the Move, if possible with the ER4-S?

I’m looking for a USB DAC with autonomous power supply (not USB-powered). I am now using an M-Audio Transit USB as DAC with very good results for my expectations. The issue is that the Transit is USB powered and this causes a very audible noise (even with no incoming signal). What would you...

I've always read that AAC (MPEG-4) is very sensitive to the encoder used for compression and that iTunes is the best encoder. How does the Nero encoder compare to iTunes? What compression codec would you recommend for purchasing music online at equivalent bitrates: Lame Mp3, Nero AAC or Wma? Thanks.

I've tried to install Foobar2000, EAC and iTunes (latest versions of them all) on my new laptop that runs with Vista and none of them has been successfully installed. Does anyone know if there are incomaptibility issues with this software? How can I downgrade to Windows XP? Is it possible to...

Is wma lossless an acceptable lossless format, equivalent to Apple lossless or flac? When playing wma lossless files in Foobar 2000 (v.0.9.4.1) I can hear very audible clicks, some kind of "strutter". This doesn't occur with any other lossless or lossy format. Does anyone know why?

Is Rockbox the only way to get gapless playback with an iMod? Is it sure to install Rockbox into the iMod? How much more battery consumption does Rockbox cause? Is it better to remove iTunes managed files from the iMod before installing Rockbox, since Rockbox doesn't recognize iTunes files...

I know a warm/hot tactile sensation is always very subjctive. Therefore I looked for a comparison: During normal operation my DA10 has the same warm touch as an operating external HDD or the warmest part of my laptop. It's by far the warmest audio component I use. Does yours also get that warm?

Has anyone done a face to face comparison between the RWA iMod and a 5G stock iPod, using the same amp and a decent dock cable in the case of the stock iPod?
