Woah... tell us more!

i listened to this at Canjam....great little amp....must have more details on price.

 

[TheMarchingMule]

Hey hey! Very interesting. If the price is right, I may just get this to drop back into the dynamic world.

 

[mrarroyo]

I listened to a prototype at CanJam08 and I felt it was a very nice sounding amp. Lots of detail, clarity, and musicality. If the production unit has been improved futher it will make for a very nice amp, specially if priced right.

Good luck on your new amp!

Just wondering what difference does the number of tubes make to an amp, I have seen one with three tubes.

 

[jinp6301]

Just wanted to say that this amp sounds great with grados

 

[immtbiker]
