herron vtsp-2

I was waiting for someone to write a review on this amp but no reader has done it yet!
Anyway, I am a happy owner of this amp now. I just want to share some experience to others who wants to know a bit more about this amp.
I was lucky to buy it 2nd hand last year at almost half of the retail price.
The unit came with Sovteks and displayed Version 1 at start up. It sounded good but was not as quiet as the reviews had said. At the time, I found it sounded ordinary.
Later, I found out that version 2 upgrade is available for free if you sent it back to the factory. I did that and also re-tubed the unit. All version 2 units now tubes with EH 6922.
The difference is night and day!
There are major changes to the volume settings. It makes it as quiet as any SS amps and thus brings improvements to all other departments.
For me, this unit will be a very long term partner and is one less problem that I need to worry about in my up-grade path.
One interesting point I like to tell about this amp is that I can not hear it any more!! It has some how disappeared from the system. I can still hear my Jadis power amp. I can still hear my Thiel speaker I have forgotten I have a pre-amp!
I hope other Herron fan can continue this thread with their experiences.

Thank You.
