spritzer Posted August 4, 2010 Report Share Posted August 4, 2010 The 717 is an excellent amp and the best value out there for a pre-built amp. It is basically a KGSS with a few "tweaks" and the stock crappy Stax PSU. Now those "tweaks" could be removed and the amp turned into a KGSS... There should also be similar mods on the horizon for the 727 just as soon as Craig starts to read my emails... Quote Link to comment Share on other sites More sharing options...
mypasswordis Posted August 4, 2010 Report Share Posted August 4, 2010 Yeah I sent him an email asking the price of a SR-001 Mk2 and he didn't reply. Which is cool, since I guess I've decided to wait for the new model. Quote Link to comment Share on other sites More sharing options...

FrankCooter Posted August 9, 2010 Report Share Posted August 9, 2010 I think that DHT's have the potential to make a signifigant improvement in the Stax mids, which, like the K1000, can be a little too cool and thin for some. However, a 2A3 through an SRD-7 is way too small for the job. A 300B isn't big enough either. On the other hand, an 845 might be very interesting. In the end though, you'll never get the full benifit of a DHT out of the SRD-7. I use a lot of transformers in my designs, but there's no way you can run the output of a 16:1 step-down into a 23:1 step-up without degradation. If you're into DIY, Electra-Print makes transformers specifically for this purpose. I'm building a DHT electrostatic amp now. Should be running later this week. You'll see it here.

kevin gilmore Posted August 12, 2010 Report Share Posted August 12, 2010 OTL fully direct coupled DHT. This is the way Lots and lots of power supplies. Quote Link to comment Share on other sites More sharing options...
spritzer Posted August 12, 2010 Report Share Posted August 12, 2010 Not only that but a lot of very expensive DHT's... . I'll build one sooner or later though Quote Link to comment Share on other sites More sharing options...
