Stax SRM-007tII vs Stax SRM-727II - Page 3

post #31 of 40
well first up, give be a pot or give me death. I've grown to loath steppers because the level is never "right".

You can find the KGSS schematic on www.headwize.com under the projects link. It too is balanced like the 727 but the reason why I like SE is the simplicity and fewer parts. I would much rather have a SE 1. drive stage and then use a transformer as a phase splitter but I'm a SET guy at heart and transistors are icky...

It can handle 30v because there is an internal switch to bypass the volume control and run the amp directly from a preamp.

The non-NFB isn't really an issue for me as Stax has made some of the best solid state amps ever designed. They were speaker designs but they are still unmatched. NFB is good to get better numbers but if the circuit behaves well without it I see no reason to poison the sound quality with NFB.

Just go with tubes and get it over with. I'm toying with a few push-pull SET ideas and how they could be converted over to Stax duty. That is really the ultimate Stax amp.

Hello I was interested in buying a SR-007 and SRM-727 from japan and i was wondering if the SRM-727 could use European 220 V without converter?

The Stax amplifier you buy in Japan are set up for 100 Volt, and wont take 220 Volt.
There might be possible to rewire the input to the transformer. But the easiest solution is to use a voltage converter...

Thank you

Has anyone compared SRM-727II to SRM-727 or KGSS?
I mean AB test not specifications.

The II means nothing as that is only the export name of the 727A. There is no 727.

Can anyone tell me how the SRM 007t compares to the SRM007ta?
Has anyone written a review for the SRM007ta???
Thanks Scottsmrnyc

The subject of this forum is

Stax SRM-007tII vs Stax SRM-727II

Does anyone has an opinion on which one is better for the SR009 and why?

 

Thanks.

I haven't heard the SRM-007 with the SR-009s, but here are my thoughts on why I selected the SRM-727II:

 

1.) The SRM-007 doesn't self bias the tubes. Leaves that up to the user.  frown.gif

2.) The SRM-727II has 450 Vrms (or 1273 Vp-p) and the SRM-007tii has 340Vrms (or 962 Vp-p)

3.) Many ears that I trust on Head-fi really liked the SR-009/SRM-727II pairing. And you can add me to that list now too!
