OPPO 105; how to beat it and at what price?
How about $800. That is what I charge for my basic mod plus the zero feedback fully balanced fet output stage for the 105 or 105D. Just had a customer get one and he loves it. Another $1000 in other advanced mods (linear power supply, low jitter c...

The Jupiter copper caps are paper and wax....no oil.

The Copper foil wax paper Jupiter caps are now available. They will be at the dealers within days. Values from .001 to 1uf at 600V. Round case, pure silver leads. These MAYBE the new reference. Not cheap but a lot less than Dueland. A .22uf is $60...

I will have mods that optionally can include a remote control volume. Looks like this: discrete I-V converter for each phase (no op amps) then a shunt volume control between phases and then zero feedback jfet buffers on all 4 phases (for full bala...

You cannot tell how a cap sounds after 3 hours. Modded Wima caps need a couple of days before they settle down. The value of the bypass cap will also effect the frequency balance. Generally the smaller values add air and as you make the cap larger... 
No binding post a good idea?
I am the first person that I know of that thought of, promoted and sold products using the "binding post bypass system". You simply run the wires to the outside of the amp or speaker and wrap the bare or tinned wire around the outside of the bindi...

Jupiter copper foil caps coming in 3 weeks. Yes, values from .001 to 1uf at 600V will be ready in 3 weeks. So far, everyone has preferred them to Dueland copper cast and VSF. These will be in a round case. Later this year 100V flat stacked version... 
Sony HAP-Z1ES Hi-Res Music Player RMAF 2013
The S1 and the Z1 are for different people. The S1 has a built in power amp and more features but does not have the ES tweakiness (therefore better sound via line out). The Z1 is for those audiophiles that have a serious system and already have a ...

I have seen pics of the inside of the Sony and it is going to be easy to do some serious mods on the player. Most importantly, I can remove all the output stages (op amp based) and replace them with my discrete fet I-V stages. Other mods can be do... 
Coincident Pure Reference Extreme
All the reviews are raves as it should be since it is so simple using state of the art parts and simple xover. So simple in fact that you can make a better verion for much, much less. Buy two Accuton $900 mids, two $360 Accuton tweets, buy two cap...

Damping the caps simply means having them hard mounted to something. A lot of people have the caps up in the air or off a circuit board....not good. Also having the caps and xover inside a speaker is really not a good thing. Use a hard wired outbo...

By the way, I have carefully removed the end fill epoxy and wires on a .1uf JB JFX cap and attached my own 22 gauge wires using Wonder Solder Signature and the cap is fully functional. I am going to try some 2uf caps with different wires and see h...

Cap tests have to be done very carefully or wrong results can occur. The caps have to be fully burned in, with the outside foil to ground or output, damped and the leads need to be damped. Not doing all the above will result in misfire. Never list...

Upsampling all PCM to double speed DSD is what Meitner and Playback Design do. With mods this might be killer. I am thinking I might work up serious mods on this baby.

The cap on Humble Homemade HiFi site is NOT the new cap from Jupiter. The Flat stacked Beeswax cap has been out for over a year but just now got reviewed. This brand new not yet released Copper foil cap is suppose to be way, way better than the cu...
