She arrived this afternoon I am going to take it slowly with your V8 as I want to get it sounding absolutely mind blowing. The two ohm "output impedance" consists of two horrible wirewound resistors (1.2 ohm) slap bang in the signal path so I am going to change these for either Alan Bradley or Shinkoh types. This will definitely change the sonic signature for the better, I just have to decide which ones sound the best... I am looking for organic and dynamic.
The 4 x resistors in the power section equate to 10 ohms so I am going to replace all four of them with ONE high quality, non inductive, 20 Watt / 10 ohm Mundorf M-Resist, they are £10 each so want to be good at that money!
I have made a start this evening..... fitted the Panasonic NHG 3300uF caps and some Panasonic FC 1500uF.... I have bypassed the 3300uF NHG with top quality 100nF / 630V polyprops and have bypassed the 1500uF with WIMA 100nF metalised polyester..... The EVOX / Rifa 470nF polyprops have been bypassed with 33pF polystyrene film caps.
Tomorrow I will fit UF4001 ultrafast diodes and probably bypass them with polystyrene film caps.... I want the amp section of this V8 to be pretty much "flagship".... I am not going to touch the DAC section at all as I know you don't use it much, not a lot can be done anyway apart from swapping out caps.
Nope, I'm going to concentrate on making this V8 your "reference" amp.... plenty of tuning by ear I have fitted ceramic valve sockets and will be populating them with a pair of 6N23P-EB which I will match on my Tube Imp......
Off to order those resistors as I believe they will play a key part in improving the character of the amp.... I will "voice" it to my ears and hope you like it......
