Final results of six months of tube rolling for the Mini Torii-II I purchased last summer.
Any Comments?
A Mullard OC2 for a OA2 is a big improvement.
A NOS RCA OC3 for a stock OA3 is a very slight improvement.
Time to just listen to the music.
Earlier Tube Rolling and Set up:
FINAL RESULTS AFTER TRYING OUT A BRENT JESSE RCA 6V6G ST, COKE BOTTLE:
Valve Art 350B-coke bottle,blows away the RCA 6V6G ST in my system (mini Torii driving a mid/tweeter at 1000 hz and above)
Amperex NOS EZ80 from Brent Jesse (white lettering with a cartoon of a tube playing a trumpet - Bugle Boy)
Valvo/Mullard NOS Blackburn 12au7 (these are the authentic Mullard Blackburn plant tubes made in 60's with "Gf2/B3J5" and "Gf2/B8E5"etched codes). Even with the Mullards12au7s I use the highest neg. feedback setting for Digital Playback (thus the Mullard 12au7s create a more flexible system).
This is a great combo, 3d deep sound stage, not too hot or bright, airy sound, great definition of instruments, sound stage that is wider than my speakers, balance natural sound.
My System:
Upgraded Linn LP12
Hadcock 242 Tonearm with a Grado Statement Reference1 Wood Body Phono Cartridge.
Vacuum State JLTI Phono preamp (one of the best phono preamps available for under $5k)
Aesthetix Saturn line preamplifier with upgraded Mullard 12ax7 and Amperex Mini Watt SQ 6922 tubes (a great preamp)
Feeding a highly modified custom Behringer DCX2496 two channel digital crossover.
Feeding the Mini Torii for above 1000 hz to a Emerald Physics CS2 mid/tweeter (Selenium D220Ti 1" Titanium Horn Driver 8 Ohm).
Below 1000 hz, a Sunfire amp is being used into dual 15 inch open baffle woofers
