If bi-amping is so great, why do some high end speakers not support it?
My first foray into bi-amping around 1987 was a total disaster: I tried bi-amping my Magnepan MG 3A using an ARC D115 mkII on the Treble/Midrange and a very powerful (400W) solid state amp on the bass that I had on loan from a dealer. The Magnepan... 
Retubing an ARC VT100 mkll
Oregonpapa:The REF3 and PH8 both use a 6550C for power supply regulation.Are you suggesting that based on these data points, Sinaker01 should use the 6550C instead of the KT120 as power tubes? Perhaps you haven’t noticed, but ARC has replaced the ...

Retubing an ARC VT100 mkll
I retubed my VT100 MKII with the KT120s without any issues. The improvement in sound and perfromance was across the board in all sonic categories. In fact the amp seems to run cooler with these tubes.

Oracle MK VI upgrade
Ella4ever:Hi. I am considering the upgrade also. We both have the MKV with granite base. Did you drill and tap the holes for the MVSS yourself, and if yes, was it a difficult task?I am interested mostly in the MVSS portion of the upgrade.Thanks 
Sunfire subs
I am using a stereo pair of Sunfire Signatures subs with my Magnepan 20.1s with great success. I previously used them with 3.5 for many years. Improperly set up Sunfire subs will demonstrate all of the negatives mentioned above. For best results:1... 
Magnepan 3.7's versus 20.1's?
15' is fine povided you place the tweeters inside. My 3.5s performed well in my listening room with about the same width. Currently, I have the 20.1 in the same room without any problems. 
ARC VT100 with KT-120 tubes ?

At What Point is the Needle Damaging Records?
Jmoog08 Have you tried demagnetizing your cartridge before assuming stylus damage? 
best amp for Magnepan 3,7
Jallen:The 3.7s do not have an external x-over box. Thus b-wiring or biamping can only be accomplished after major internal modification of the speaker, which would void the warranty.
