have you compared the mustang to the predator(fully burned) , and is there much power difference?
how the bass and overall wwarmth compare?

I think the P-51 has enough juice for the D5000, and almost but not quite enough for the HD600. The P-51 does seem to have slightly more power than my Predator, although I thought they were spec'd the same.

Now, if you were getting HD600/650 then the 9v SR-71a would be more important because high impedance phones need the voltage swing more than they need current.

thank you!

Does anybody know where I can find the RSA Mustang technical specifications?

 

[jamato8]

I would email RSA and ask the questions though I would imagine right now they are very busy with the release of the Protector.

 

[kayser]

I already emailed them and asked about technical specifications and about shipping cost. Well, they replied me, answering only my second question.

I've been looking for the specifications as well however from what I've read Ray Samuels doesn't have much of this information about his amps out in the public.

And what is the reason?

 

[tnmike1]

with his reputation, build quality and overall amp performance he doesn't need to release information about the guts of the amp. The same reason he paints over the identity of the opamps and other electronic guts.

Thanks a lot, Ray!

So there you go. :^)

Has anyone tried the P-51 with the 701's, how well will it drive them?

Would someone mind explaining some of these specs? Does this mean the amp can't run 600 ohm headphones since it has "5 ohms-300 Ohms output impedance". It is "3.7-4.2 volts Lithium ion powered" so this mean the SR-71A has more voltage swing potential since it has 18V?

I wish to ask if the Mustang gives significant improvement in SQ over the iBasso D10 with topkit? And does the Mustang have good synergy with the Ortofon e-Q7?
