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.

Hi Sirlee,
My Jadis is the DA7. Newest model of the Defy7. Honestly, I have a bit of regret with this decision. It has too much character of its own and is not as transparent and airy as the Audio Research VTM120 it replaced. It has problems opening up the bass of my Thiel 2.4. Mid-range and vocals are hard to beat though!
I hope someone can give me some suggestions of how to go from here?
Change amp or change speakers?
I have a VTSP2 v.2 It took many weeks to break in, sounding a tad light weight initially, but now I would also characterize it as "neutral".
I am very tempted to try some tube rolling, despite Keith Herron's assertion that his carefully selected and matched EH 6922's are hard to improve on. There's a very slight fowardness/glare of upper range vocals that I suspect is from the Russian made Electro-Harmonix tubes (standard, not gold-pinned). Six higher-end NOS tubes such as Amperex White or Philip Miniwatt will be pricey though, with no guarantee. Anyone else ventured that route?
Because of its neutrality, it clearly defines any system changes, from powercords (on it and other components), IC's and just about any other change up or downstream. I therefore don't quite consider it "plug and play" cuz it rewards system tweaking. And I love it!
A sextet of NOS Philips Mullard (Holland) 6922's, 1960's vintage should be arriving this week. I'll let you know!
