Vintage vs New

KLH Nine full-range electrostats driven by a pair of Futterman H3AA OTL amps is still a world-beater combination! I have this in use!

Why not both :-)

Thank you! 
According to some, it's as if copper wasn't discovered untill the last decade.

tomic6018,396 posts07-05-2021 4:15pmwell….a properly upgraded (Mike Samra )and maintained MC240 with the right tubes ( Andy at VTS ) is probably as far as ya can get a transformer tube amp. The MC240 xformer one of the best ever.

<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>

I looked at your page. I could see the Samra’s PS upgrade in your 240..
He sure could get a 240 to sing.. You should hear the way he does up a C20 NOW.. He did up the phono stage like I’ve NEVER heard on a Mac..
I added Super Hexfreds and Vishay copper resistors.. after he did his magic..

I have to many irons in the fire and ZERO energy to get er done.. :-(

I have a C11 (Samra) I’ve never pulled out of the box. I have new glass for it to boot.. Fixed a Bass pot too.

REMOTES.. that is my problem.. a darn remote.. I use a Parasound Zpre3 in the tape loop on the Mac valve preamps... Very nice.. and adds a little DAC with sub out and remote sub volume control.. Nifty little preamp and a C20 to boot.. I LOVE IT.. You should hear what a C20 (S) does to ANY class d.. It’s like magic.. MX110z for that matter..

Have you tinkered with any of the class ds, Electro-stats and that MX110z. I bet it would blow your mind too..
Nothing like a planar designs and Ribbons.. I keep looking at Sound Labs and Apogee :-). Before I kick.. LOL

Ya the 110Z was hot Rod  by two guys Modeferi of Mac fame and a great tech w ears here in WA - Elite Audio Tech only works on Mac, logging road for driveway to shop..  
the Apogees are wonderful, but so are my ESL 63… nothing in that room is stock… well the NAIM is…
good on ya Heavy
