You made the right choice making it the same size as the iPod Classic IMO.

I got up this morning. The SR-71A didn't sound so great. I assumed either my hearing or a phase, my hearing or the amp. Tonight with it running all day the sound is blooming. Very open with a beautiful reverb on my live recording by the Grateful Dead, Terrapin Station. I actually thought I was still plugged into my Woo 6. I was thinking, because I have the Woo turned on, that the different rectifier I had just put in was sounding very fine. Then I looked down and wondered, were is the headphone cable? It was plugged into the 71A. Talk about a blind study. :^) No the the Woo 6 modified and the SR-71A do not sound just alike but the 71A sounded so good and I was enjoying it so much that I could only assume I was listening to my home amp and my 6 does change sound with different rectifiers.

Well the journey continues.

Hrm....This is a very intriguing little amp. Maybe after I sell my iBasso Boa I can pick this up

That's pretty funny.

Tonight I was listening to various headphones, and I thought I was listening to my Koss ESP950 electrostatics via Woo GES prototype - when I reached up to my head to take them off I found that I was listening to my HD600 through a $400 Grahm Slee NOVO discrete SS amp.

I can tell the difference, but I was enjoying myself so much that I assumed I was still listening to the stats. Great minds get distracted alike!

 

[jamato8]

Yes, that is it, Great Minds. lol

I am ordering some of the new lithium rechargeables that have a storage of 500mA's! I am also getting some other types.

Back to the SR71, there were some preferences with regards to batteries used. I wonder since the eneloop AAA sound the best to me in applications that use AA or AAA, how the low discharge 9 volts would be? And then there is the true 9.6 volt, 9 volt and 8 something volt.

Just placed the order on a white SR-71A. Excited

What color? Geez, I'm excited too. Your going to have a great time.

 

[Tranzaddict]

anyone know if the 9.6 volt battery will work?

Sure it will. Any of the 9 volt batteries will work if they fit. I have a pair of the 9.6 rechargeables coming.

i do have some 9.6v rechargables batteries coming too! glad to hear it will work. Wanted to order some lithium 9v initially but the shipping for it is just not worth it!

 

[jamato8]

What would the shipping for the lithium be?

 

[HeadphoneAddict]

I was told the Powerex 9.6v were too long for the SR-71a. Hmmm. I use them in my HR Micro DAC and Micro Amp because the higher mah batteries are too fat to fit in it, while at least these are not too long. I never tested battery life though.

Don't you be saying they won't fit! :^) I read that they have been resized. If they are slightly too long I don't care the back plate doesn't have to fit snug there is leeway with the thumb screws.

Well I hope they fit. Maybe it was another 9.6 that I read had been resized. It is the 9 volt lithium rechargeable that was resized. Oh well, I hope they fit. Now where is that hammer??

Well, you can always use an exacto knife to trim the battery shorter.

Okay guys, here's the deal. I was the one who originally said the Powerex 230mAh 9.6v batteries would not fit. When I received my amp, I had those batteries charged and ready to go. (I also use them for my Headroom Micro gear.) And at the time, the batteries slid in okay but I could not fit the back plate on flush. There was a 1/16" gap. Not wanting this, I ran to buy Duracell alkalines which are about 1/32" shorter and still had to tighten the screws very tight to get the back plate on flush.

After they expired, I used another set of Duracells and just today charged up some new Accupower 300mAh 8.4v batteries.

So earlier tonight I just measured the Accupowers vs the Powerex and they're the same length! &^$@!

So, anyway I tried the Accupowers and now realized they are thicker than the Powerex! Double &^$@!

I had trouble getting the first one in, but the second one went in easier although I was still forcing the issue.

Bottom line is that with a little extra pressure (read "a lot") I was able to get the Accupowers in and the back plate flush. It seems that with a little time, the spring clips that contact the batteries give and allow the use of slightly longer rechargeables after all.

Sleep well, my friends.
