Just to conclude the argument( at least from my side)
1-For the friend who plan to drop by to HK show room, i must say I'll leave on friday, sorry.
2-About potentiometer, I agree with Gilmore, it's not attractive to see, but a 4 section potentiometer must be long and never nice.
Dact are very nice to see but do not give enough precision in volume adjustment so I never use it ,(is hard to find the right volume level ) The RK114
( that cost much more then 9 $?? ) apart to be practically the only 4 section pot really available on regular production, have the great advantage to be
modular, so form a bunch ( I buy stock of original Japan made straight from their German branch) i can select the better matching
sections for left to right precision and phase to phase precision, we set our limit in 0.02dB.
The motor ( easy to dismount ) is left in place in order to make possible a future upgrade to remote control
3-The power resistors are placed on the edge of the bottom plate, close so the side heatsinks so almost all of heat goes straight to the the side wings.
4-A top quality switching power supply, who have the working frequency far away for audio spectrum without any measurable EMI, followed by a traditional RC filter based on capacitance multiplier, deliver the cleanest DC supply, and it's totally insulated by the main AC noise, and even immune from most common ground problems,most of the ultra expensive "power conditioners" work on this principle apart of battery backup/buffer option. Listen to believe.
