Sound of SED Winged C KT88 vs. SED Winged C 6550's
I think sounds best with KT-88's rather than 6550's and the best new production KT-88 is the Gold Lion re-issue. 
Anyone try the Fosgate Fozgometer Azimuth meter?

Buy tubes from Audio Research or not

Mods for ARC preamp / amp
Smoffatt - What is the REF3LE and how does it differ from the REF5? Thanks.

AR highend equipment by Cello
I think only about 150 pairs of the Cello Amati speakers were made. They occasional come up for sale on Audiogon.

AR highend equipment by Cello
Rickmac - The Cello Amati speaker was closely based on the AR LST speaker. Mark Levinson designed the crossover. It was considered high end with a suitably high price tag. 
BAT VK-60 stereo to mono jumper
Just as Semi says: Remove the jumper, then either cut or unsolder the wires joining the 2 sets of speaker terminals. Those wires will be obvious. They only connect each set of terminals. Do not remove or cut the wires from the circuitboard(s) to t... 
BAT VK-300K SE vs. Ayre AX-7e integrateds
What does the BAT do wrong?
