Hallo,
also suggested in this forum I have “linked” the photos from imageshack.com because my usual web photo service doesn’t work (servimg.com). I hope it work all…...
my system for the amplification/loudspeakers:
Marantz SC11S1 preamplifer;

Marantz SM11S1 stereo amplifier x2 (in bridge mono configuration);

Kef 105 (mk1) two pair in serial configuration (nr.2 left channel and nr.2 right channel);

As we know the “bridge mono” configuration of stereo amplifier has the advantage to moltiply the power of the amplifiers but has the downside to halve the “sensivity” of the electrical resistive load of the loudspeakers. Every Marantz ampli in bridge mono configuration has 420w on 8ohm of exit power, the kef have the “nominal” impedance at 8ohm (halved to 4ohm for bridge configuration). But I provide to connect two kef 105 in serial for every channel so the impedance will be added (4 ohm first kef 105 + 4ohm 2nd kef 105 = 8 ohm). This configuration has the advantage of the bridge mono configuration without downside.

here a test of the tonearm….sure is not friendly of most of analog passionate.

Morsiani is an italian artisan that at this time is not more in activity, but is holder of a particular kind of magnetic antiskating very efficient. He has provide me his tonearm with the special configuration of the wires that has no interruptions from the pin of the pickup until the xlr terminal to the phono stage in…..

I have provide to replace the “cheap” power supply of raspberry with a more serious linear power supply…

xlr cable to preamplifer
At this time I don’t provide to play the music by streaming with web sources, but only with the music storaged in my NAS.
The optical “source” at this time is an old Sony SACD/DVD/CD player, and probably will be changed in near future (DVP NS955V)

Wires: all analog signal cable are in multifilar copper enamelled litz (some manufactured by Morsiani and others by Aqvox). Drive loudspeakers cable in normal OFC copper and the power cable of the electronics made by myself with industrial schermated wires and good thorns.
I’m satisfied of this, but I have the necessity to change home (as soon is possible) because the room where is placed the system isn’t good for it…...
