Well size isn't everything, it's what you can cram in a small box that counts... My KGSSHV is smaller than the Stax amps but is much more powerful and with a completely regulated power supply. The Carbon isn't much bigger and more than twice as powerful than the mini...
Plenty of threads here where we rip the amps a new one. We've not been as active in this but that should change shortly. Time to expose the shit that's popular on HF.
Something to offset the fucked up news above, a pic of the ever growing Stax museum. I clearly need a second display case in the living room:
009, SR-Omega and HE90 on the top shelf
Two SR-1's, SR-2, SR-3 and SR-5 on the next shelf
The 404LE, SR-SC1, Lambda Signature, Lambda Nova Signature and Lambda Pro
Being all abandoned at the bottom is the SR-X Mk1.
A lot of other headphones all over the house plus a lot more in various stages of restoration.
