R9.9 is the matching top of the range monoblock power amplifier, the top uses cherry wood with large machined aluminum front plate. Each channel uses a direct heated triode 845 for single-ended class A amplification. First stage goes through a  E88CC and 5687  as the powerful driver stage to realize an output power of 28W, with no global negative feedback.Point to point wiring is used with Kimber high purity copper hook up wire. Resistors are Chinese military grade metal film. Signal coupling capacitors are from Rel-Cap/PPMF. R9.9 has very good driving power due to a strong power supply and well designed output transformer. The filament power supply and the high tension power supply are separated, using audio grade electrolytic capacitor and improved EI power transformer and choke for good power filtering and reserve. This enables good handling during dynamic swings in music. The driver stage unlike others does not use inter-stage transformer coupling or power tube. Instead the US 5687 NOS is selected to do this job with its adequate driving power and musicality. The advantage being greatly reduced distortion .
