Works and sounds incredible with both the SR1a and also, in case you didn't know, this is a phenomenal amplifier for inefficient planars and any other conventional headphone. I never heard the Susvara sound better. It also amplifies efficient speakers and sounds great doing so. This is an incredibly versatile amplifier. I have not heard the SR1a off Raal's new tube amp, but short of that, this is so far in my experience the best amplification for the ribbon headphones.

Includes power cord and a custom (not Raal) adapter for using conventional headphones out of the ribbon output. Not recommended except for the most insensitive planars like HE6 etc. For most headphones, just use the XLR or 1/4 inch output.

Please note, the red light on front panel flickers when turned on. I do not know why but it has never caused an issue and does not impact performance.

Price includes insured FedEx within CONUS. Any other destination shipping is at buyers expense and risk.
