jamato8, all have been sold out?

I don't think so but the last I heard it was getting close. I would contact RSA and ask, if you want one.

I received mine last week and I'm #280. Sounds like he couldn't have sold that many in a week.

With lower resistance you have a more instant delivery of current, which in turn adds to the dynamics and transparency because of decreased smearing of frequencies. The Tysonic does this with the 71A and to my ear takes it to a level of refinement that totally adds to the enjoyment of the music. The 500mA is a good battery but does not deliver this refinement. I use it because there are times when this extra bit of musical quality isn't going to matter due to external forces when walking around etc.
I received my iPower 500mAh Li-Polymer few days ago, been listening to it. It makes the SR-71A sounds like a predator, the attack is almost as fast as the predator. Using the powerex 9.6V gives a more dynamic sounding, more musical compared to using the iPower.

I own and have used the Maha 300 mAh 9V (7 cell), Maha 230 mAh NiMH 9.6V (8 cell) and the Tysonic 200 mAh low discharge 9V rechargables in the SR-71A. In terms of delivering greater effective dynamic range, blacker background and a consequently greater palpable sense of the music, my own ranking is: Tysonic > 9.6V (8 cell) > 9V (7 cell)

It's interesting that you've noticed what reads like a similar effect between the Li-Po and the 9.6V, as I have noticed between the higher capacity powerex 9V (7 cell) and the powerex 9.6V (8 cell) batteries. If you have any interest and the disposable cash to try a pair of the Tysonic ultra low discharge 9V, there's some basis on which to think that you may find that it was worth a try. The difference, I think, would only be likely to affect real listening enjoyment if using the SR-71A (as I do) as a stationary transportable in a not-too-noisy place where the subtleties can be heard and appreciated.

An interesting description of the SR-71A using the Li-Po batteries: it sounds like a Predator. That gives SR-71A owners a reasonably accessible way to find out how the Predator sounds. Thanks for that.

Maybe I will get the Tysonic ultra low discharge 9V in the near future as shipping to my location, Singapore is pretty expensive.

I got mine a couple of weeks ago - no.212 so I guess they must be well into the 300's by now.

I am getting one very shortly just emailed rsa on availability and I will buy from ttvj if I cannot get it from rsa which I highly doubt

I was a little skeptical regarding jamato's observation that the Tysonics sounded better than other 9v's, but after joneser and sbulack piped in I couldn't resist and got myself a set. Sorry jamato...safety in numbers

I haven't "scientifically" compared the SR71A with alkalines vs. Tysonics (since it's a pain and takes too long for aural memory to hold while you switch), but I did notice right away that it does sound different with Tysonics. They seem to make the SR71A sound a little more like the SR71...a little more open and natural.

Now I'll have to spend some additional time comparing my SR71A and SR71 again...this new quality could be the ticket to finally help pick a winner.

ok guys just spoke to rsa they are still in stock so you will be able to grab one no problem

As you seem to be coming closer to making a preference decision between the SR-71A and the original SR71, I "almost" hate to ask this - but here goes - If using Tysonics in the SR-71A improves its sound sufficiently that you might pick it over the SR71, would you want to hear the SR71 powered with Tysonics?

That had crossed my mind almost immediately. Darn this hobby....

Supposedly the SR71 was voiced by Ray with regular old Duracells....hmmmm.

There are times (especially in this hobby) at which selected areas of ignorance really CAN contribute to the holder of it a kind of bliss, if you let it. (Kinda like taking the BLUE pill).

anyone around compare to iqube? If so what's your take? I love the iqube but may by a second amp especially if it works better than iqube with earth beyers v3 & v4. Any takes?
