Herron VTSP-3A

I bi amp using four M1's. The power amps do what good power amps supposed to do (very well). They just do their job day in day out. They don't get in the way of the music they just amplify. No drama!

With the updated SP3a. I was using some rather cheap and nasty interconnects with my SP3 and did not notice anything wrong with them. However the 3a is much more revealing so, in order to subdue some harshness when I updated, I updated the interconnects as well. Fixed things up nicely, thank you very much!

Hi Rossop,

Just out of curiosity, what speakers do you have that you are biamping using the (4) M1's? Do the M1's do an adequate job on the low end, i.e., have enough grunt?

I run Focus Audio FS888. They are about 91db sensitive and a fairly easy load to drive. As I said before the M1s do a great job. They don't run out of steam and since the upgrade of the preamp I use the low gain setting because of the reprogrammed volume contour. I like to use 40-60 on the volume display. Unless you are in a very large space the M1s have plenty of grunt.

I own a VTSP-3A and VTPH-2 and based on the sound of these two components, I have also ordered a pair of of M1's and have become a dealer for Keith here in Western North Carolina.

This is great sounding audio gear and I've owned a lot over the last 30 years.

The M1's will be taking the place of a pair of Pass XA100.5's and this will truly be a test of how Keith's amps sound. I love the Pass amps, but cannot become a dealer for them so I will take a shot here.

I'll try to keep you guys updated.

I have the VTSP-3A, the VTPH-2 and four M1's. The two preamps are standouts but the M1's are all class as well. As I said before: they just do their job(very well).
When I first got my Herron gear I had trouble with the pre 'dropping out' all the time. This was not the fault of the pre but due to the fact I was running it through a step down transformer. The voltage was too low. First Keith Herron replaced the preamp straight out. When the problem persisted with the new pre he bent over backwards assisting me to rectify the problem.
When I updated to the 3A I was having a problem of some harshness at higher volume levels and Keith pointed me in the right direction(cheap and nasty interconnects).
It would have been easy for him to let me go figure but he helped me out every time I had an enquiry.
Sound like a lovefest I suppose but I really appreciated his help. A lot of designers would not do this.
Im not a dealer,just a happy customer!
