Symdex speakers any information on these?

Faust,
I drive my Gammas with a Pass Aleph 3 also. Leland Wallace of Symdex was a Pass dealer at the time and I agree they are an excellent combination, though they would probably benefit from a bit more Pass Labs Class A power. Did you fill the bottom of the cabinet with sand?

I got them used and the bottom of the cabinet was already filled with sand as they are very heavy. My room is not very large 20x14 and they sound as good with 30W Aleph 3 as with 110W RG11 in this room.

I also tried them with my DNA-1 and it was a very nice match, but a bit too much power for them, I feel.

What I like about these speakers is ability to drive them with almost anything. They sound good with powerful SS and equally good with small tube amps.

These are my rock speakers at the moment. I also have SAP Trios that I use for jazz, vocals and other gentler music :)

I also just got a used pair of old Gallo Reference v1 balls and will be comparing them with Symdex. I am really surprised how good and undervalued a lot of the "old hi-end" speakers are, especially for the money you can get them now. Little Symdex put to shame many modern speakers in $3000 price range, and even some much more expensive speakers.

Hi Kingcrim55, curious whether you found any Sigmas to buy. If so, what system are you using them in? I have a pair from early '80s I think. Blew out a woofer on one side playing a Dave Grusin direct-to-disc album too enthusiastically. Now I'm looking for suitable drivers to restore them. Would welcome any suggestions on electronics to drive them with.

I have a set of these speakers in excellent shape in original boxes and packaging and took them out to listen a few weeks ago.  They still sound great even by today's standards.  However they don't have much low end.

Hi everyone,
I just noticed this old post and wanted to share that I do in fact have a pair of very hard to find Gloss Black Sigmas in their boxes and ready to be shipped as soon as somebody contacts me for purchase.
These specific ones are in number sequence, made at the same time and where purchased here in New York through Ears Nova and had the drivers replaced by Leland and then shipped back to me, never to be used again. They are still sitting in their boxes for somebody to enjoy them. 
Please contact me for details and arrangements for purchase.
Cheers,
Howard
