Some distributors might have a few, but there is very little chance now, try to look for distributors in your area.
 
Here is an example, a Taiwanese one but probably gone already: http://www.hifi.com.tw/adm_product/ad_prodsearch.php?txtCheck=yes&txtBrand=105&txtCategory=0&txtSearch=

Thanks, Padam.  I read the page and found that there is an amp called SRM-717 DM.  Anybody knows what it is?

I don't understand how it's even possible for a company to release an amp that's "bad" and cannot power their flagship headphones properly. Or are people just being way too picky and splitting hairs here? If the difference between the two would take immense concentration to hear any differences, then perhaps it's not that big of a deal?

Sennhieser did it with the HEV70 and Koss with the E/90.
 
The SRM-727II sounds somewhat dull, if you are picky about that sort of thing then it's not the amp for you.

I'm not tired to repeat: The sound of my SRS-727 system has changed completely after some use. It bacame more open, focused, bass/treble extended, there's a better instrument separation. I don't know if it's amp burn-in or O2 burn-in but it's real and it's definitely not a mental burn-in.
I admit most people here rely on a few opinions about the 727, made after very restricted use by less than 10 head-fiers.

Same as the SRM-717 sound-wise but with an extra feature: it has many inputs at the back because it was intended for 5.1 studio monitoring (there is a switch at the front and with that it is possible to listen each of the various channels)

i think it would be pretty hard for any amp to sound bad with o2

I've yet to hear an amp that makes the SR-007 sound really offensive. 

 

[jjinh]

I know it's not ideal, but has anyone compared the SRM-007t to the SRM-T1 for driving the SR-007s?

 

[spritzer]

The 007t is better if you properly bias it (which isn't easy) and put in some nice NOS tubes.  The difference isn't huge though as they are pretty much the same amp. 

 

[kevin gilmore]

The 727 uses a new 2 stage circuit with absolutely no negative feedback
around the output stage.
 
Some people like the sound, most seem not to like the sound.

No NF seems like a good idea, I need to listen to one when I get a chance.

 

[spritzer]

No NF really isn't a great idea here IMO but each to his own and all that

You don't like NF amps in general or specific in this type of application?

 

[spritzer]

With the high gain in ESP amps we need feedback.  Just compare something like the Egmont amps with or without NFB, it's not a subtle difference in the NFB's favor.  Lower gain levels the playing field.

Still I would like to listen to this amp, I generally like NF amps but with speakers.
