“A couple of months ago I bought a PAP-C1 from you and in the meantime it has found its place in my audioset. Included some pictures.
That PAP-C1 does EXACTLY what is promised: dividing the signal between 120 Hz – 550 Hz (and have the options for a bass boost and mid/high equalisation).
The turntable is a air-stabilised air-bearing 400 kgs affair. It’s my main source. The preamp is a PT8/4019a tube affair with stepped attenuators from measuring gear. The poweramp for the woofer are 2 monoblocks based on the Eimac 35TG triode (ultra-parafeed; 8 watt). The poweramp for the midrange is a stereoblock based on a single pushpull pair of 6C45’s (2,6 Watt). The poweramp for the tweeter is a stereoblock based on the E2c (1,1 Watt).
The PAP-C1 sends the low (below 500 Hz) directly to the 35TG amplifier which feeds the woofer and the mid/highs to both 6C45 + E2c amplifiers.
I’m impressed with the PAP-C1 as it adds nothing to the sound. It “simply” divides the signal as promised…
Positively surprised by the amount of ripple/noise rejection of the internal capacitors…
This is indeed a seriously well executed audio gear ! Don’t know of it’s the minimalistic and proper design or component-choice or the combination; it simply works perfectly. Thank you for making this available.”
