Test systems

This is the system set-up for the first test on May 20, 2006.
We were in my living room.
Two of my friends with a lot of experience on music reproduction were present at the test. They always agreed on the grades given. Grades are on a 1-100 scale, where 100 is the absolute best.
During the 3-hours test, for many times it has been necessary to listen again to the previous cables to get a correct evaluation.
- Sony SACD DVP-NS705V used as CD transport
- DAC with a single TDA1543 from DIY Paradise modified with all Caddock MK132 resistors and all Sanyo OS-CON
- DACT 10K+10K stepper attenuator volume control
- The first amplifier was a prototype of my EL34 PSE with Lundahl transformers, with Jensen copper film interstage capacitors, Svetlana matched quartet output tubes and Jan Philips (12AX7 - 5814) drivers. One of my best amplifiers.
- The second amplifier was a LM3875 Dual Mono Premium Kit by www.audiosector.com with all Caddock resistances and components close to the Gaincard amplifier by http://www.sakurasystems.com with a price about $,1500 and review  on http://www.enjoythemusic.com/Magazine/equipment/999/47review.htm
