Currently using Vintage Rebuilt and Upgraded T N Williamson Monoblocks circa mid 1950s using original parts, Partridge C Core Output transformer, etc. with Tungsol KT120s or Kron KT88s. 30 wpc class A. Triode Mode. The Tungsol KT120s are preferable as they forsake a tad of refinement for better grip and bite. Spectral DMC-30SS Preamp. Inefficient 83db Dynaudio Confidence 5s, which I definitely do not want to change, mean that 30wpc is wonderful for small group jazz and vocals but insufficient for large classical orchestral or choral works. Have seen used MSB S200, 8 years old and Accuphase P-4200, 4 years old, both around same price. Does anybody have experience with these amps and which would you recommend as the best choice or even perhaps something else ? Had a Spectral DMA 250 but too much trouble, eventually gave up.
Definitely prefer the treble and rhythm on present power amp to the Spectral DMA 250. Room is 6.7m x 3.7m x 2.5m H. Speakers firing along the long side.
