Ordered SR-71A today.

Yes. Ray says pay today and it ships tomorrow. I can't imagine the current supply lasting long but as he states, 300 more in 2 weeks.

If only $450 had this sort of impact with every bill we paid :)

My opinion of the Caliente can be found in the main thread about the Purity Audio KICAS amps. Neither my opinion, nor my daily use of the Caliente has changed since I wrote that opinion in that thread. In this thread, I'll say that I still use the SR-71A that I purchased back in 2008 every day, and I enjoy the sound that I get through it immensely.

Hey all! Just purchased a SR-71A. Provided I love it, what are you recommending regarding rechargeable batteries? Is it possible to get some that are too powerful compared to non-rechargeable 9v batteries? The *mah varies from battery to battery, from like 250 to 550. Thanks!

Think of the "mah" as additional battery output life. As long as it is 9v format you are good to go....except I recall that lithium batteries are not recommended.

Hi guys. I just bought this amps 71a. But not yet received it. Just wondering how is the sound compared to 71b in single ended output? Though at first i was leaning more to 71b coz it has rechargeable battere but then ended buying 71a. Reason i decided to choose 71a because all my cans and iems none of them using balance connector. And headfonia says in single ended the sound from 71a is better. But with balance output..71b is better. Has anyone ever done comparison like AB-ing both amps using single ended output? Just hoping i did not make a wrong buy

I've owned both. The SR71A wins hands down in a single ended comparison. If you go balanced with the SR71B it wins by enough to be noticeable.
