High Serial # R10's: Which amp do you use?

post #1 of 18
Thread Starter 
I own a pair of Sony R10's with a post-1000 serial number. I have heard from enough sources to believe it that a change was made by Sony to the driver in these later units to increase (the previously nearly non-existent) bass response.

My R10's have got plenty of bass; in fact, my goal with an amp has been to tame/control the bass and push for greater openness and transparency on the top end. So far, the Microzotl (all NOS Sylvania tubes— thanks, Hirsch) is working pretty well on most material, but I am wondering what amps other owners of the bass-endowed R10's are using. Please ring in; thanks.

The bassy version of the R10 sounded awesome with Lan's The Stealth. i found its slightly solid statey feel to rein in the bass and keep things tight, while still having the tube euphorics everyone loves.

For some reason the Singlepower amps do really well with the R10. If you are a tube guy, the MPX3 and Supra do the R10 justice.

The Stealth is also very good with the R10 - like Jahn said, a more solid state sound.

Do we know the whereabouts of the Serial Number when the change on the sound signature was made?

This was my experience as well. I've now sold my Stealth, but I had it in the same room as my Maestro ZR for a long time and did some comparisons. They both do quite well with the R10's but I preferred the Maestro which gave even more of the gooey warmth that the R10's are famous for, without sacrificing anything in terms of details.

Somewhere around #1000. I'm #1016 (IIRC), and I've got lotsa bass.

Just curious, where does the Microzotl fall short? I have always wanted to check one of these out.

Thanks a lot. Very useful information.

Or as Ken would say...

(Do I need to repeat it?)

I had one for years, and loved it. However, the bass never came in properly with any headphone. The highs and mids were wonderful, giving it a very ethereal type sound, at least that's how I always thought of it. Very airy, but not as substantial as it could have been. I think of the sonic signature as very similar to the original Supra, but the Supra has much better definition, and handles bass much better, IMO. Going back to the ZOTL from the Supra, there was clearly smearing going on the ZOTL that I hadn't been aware of until I became acclimated to the higher definition amp. Even so, the ZOTL is still a great amp.

I'll compare the ZOTL to the Maestro ZR with the R10's and see what my ears tells me. I've never tube rolled the ZOTL so I'm sure others can get better results with it, but it will still be fun to see how it compares to the Maestro.

the DHA3000 seems to do well with the bass boosted a bit, and the treble toned down. ( those controls are great. )

of course, they are much better on my SDS-XLR... single-ended for now.

my R10 is a late production one.

Mine is one of the last pairs made, I'm using the Ray Samuel's Audio, Emmeline HR-2. It's a bit light in the bass but the mids and highs make up for it. Very nice, clean and detailed sound but not sterile. Right now I'm driving it with the Benchmark DAC1 which is a very good source but I think a source with a bit more bass and maybe warmth would probably mate even better. (Not that I'm complaining, it's already wodnerful). The R10's got rather sterile when I drove them with my GS-1 and Gilmore V2-SE. Very detailed and clean but devoid of life.

You need a fuzzy amp....

Mine is one of the very last made, and I use a SinglePower SDS. The sound is magical.

You're right, one thing the setup isn't is fuzzy. It's rather strange though since with most of my sources and headphones the HR-2 comes across as less fuzzy than the Gilmore's but for this one it's fuzzier. Oh, well, it works!
