I tought we didn't have a Stax dealer in Montréal, i'll be checking them out for sure, thank!
A few weeks ago I found a Lambda Signature/ SRM-T1 set locally for a good price. I hadn't intended on keeping them but I liked the sound so much that I've gone ahead to the SR-507s.
I read on here that the SRM-T1 is a decent amp for the 507s.
The 507s are in the post so I haven't had a chance to hear them. My source isn't ideal at the moment, an ipod with lossless files but I will be adding a Cypher Labs DAC to that. The Ipod (through LOD) sounds pretty good through the present Λsigs and SRM-T1 but mostly with small chamber works and female vocals/piano/guitar.
I only looked at the last page. Some good pics of the drivers, post #247 gives a good description of disassembly.
FWIW, your SR-5 Gold drivers are the basically the same as what's used in the STAX SR-X Mk3.
Good luck, the driver innards are extremely delicate and just one small piece of dust getting inside can cause more problems.
I did that comparison at RMAF CanJam 2011, and I thought the 507 still had that etch and an upper mids honkyness, and the HE-500 sounded more refined, warmer, natural and enjoyable overall. I would not buy the 507 personally, as my Lambda Nova Signature that I'd brought with me sounded better (very much like an HE-500 actually).
(Gear Used - I listened to the 507 with the Cavalli Audio rig and my Apogee mini-DAC into a KGSS, I listened to the HE-500 there at the Cavalli Audio table with Liquid Fire, my table with a DACmini, and an unknown DAC at the Schitt Audio table (Bifrost?) into a Lyr amp).
As long as the music was recorded well with the intention of neutral playback, it should sound great, as long as you are not looking for bass cannons. I'm not sure how rigorously most electronic music follows this ideal, however.
I guess it's more Pshycedelic Rock but its electronic..
Most probably this question was already answered in this forum but with 1532 pages I can't find it.
My dealer is suggesting me to buy the SR009 + SRM-007tII.
I have no doubts the SR009 are very good. Is this Stax amp a proper match? How does it compare with the more expensive Woo WES?
I guess that is because (sometimes?) people just like the sound of non-linearity.
Normally, an amp shoud be powerful but transparent, that means getting in the way as little as possible.
I am currently using the Stax 323II with the 009 (while waiting for a BHSE on order)... I was in Berlin recently and had a chance to listen to the 727 and compare it with the new Malvlave. I was not impressed at all by the 727 vs the 323II and I wished at the time that I had my amp with me to compare. At any rate, after about an hour of listening to this amp I thought that the 323II was pretty good for half the price (but again, I was not able to compare them side by side). Oh, and just in case you wondered, the Malvalve was impressive, but mostly for Jazz (much better than the 323II, no doubt!), not so much for classical music though. I sincerely do hope that the BHSE will sound way better than the Malvalve with classical music, which is pretty much all I listen to.
