Hafler 9505 power amps


Do all Hafler 9505 power amps have the "Diablo", and Diamond" circuits? Or where they implemented on later models where it would then be indicated on the amp itself,or in the literature with the appropriate logo? (as they did with the "Trans-Nova" circut.)

Not all of the 9505s had the diablo circuit. Ones made prior to 1995 use the 9500/9300 transconductance stage. These also have a simple J-FET input buffer and the DC servo for offset. Though I can not agree with the statement made about the later diablo models being "better sounding", they are a technically improved design.
Hi. I am in the market for a 9505. Can you tell me how to determine when the unit is manufactured? Judging from pics of the rears of several units some are made in the USA and some are made in Mexico. Some have the speaker binding posts at the top while most seem to be at the bottom. So how does one determine the post 95 units? Or which are the more desirable ones?
Thanks.
I got the Hafler transnova 9303 since 6 month now and i
really love it.It my first power amp as i enter into the audio separate field. The best of this power amp happen
when i get the Meridian 565 in 2 ch analogue, Synergetic
Research IC and Furutech FS ALpha 1 DIY speaker cable.

All up grade produce an audible better sound. But for power
cord the only one i try made nothing so i use with the
Meridian. Since i connected a Sony DVP s 7700 as transport
to the build dac of the Meridian 565, WOW beautiful sound.

I do'nt know the year production of my hafler but i can
said it a great underated power amp i get for $400. used
but mint.I learn a lot by reading audiogon forum but
it really funny to experiment by your self.
Hi everyone

I just got a Hafler 9505 power amp and it sounds wonderful to me. Very different than my Jolida JD-502P tube amp and IMO a lot better than the Hafler DH-220 and DH500 I had previously. I'm in need of assistance though. Would anyone know where I can get replacement feet for the 9505? I've called Hafler and a couple of the warranty repair centers they mention on their site and they don't have the feet. I also checked some online sellers and they don't have the proper feet either. Any ideas or leads would be appreciated.

Thanks
