Herron VTPH-2A, Herron VTSP-360 and Herron M2


Has anyone heard the newly-updated Herron products, the VTPH-2A, VTSP-360 and M2? If so, how have these new models changed or improved upon their predecessors? Keith Herron is just about the best guy in all of hi fi and I hope that these upgraded models improve upon his already great products.

Thanks.

I own the VTSP-3a R03: happy with this.  Having heard the newest pre+amp, they are somewhat clearer, fuller and more dynamic than the previous models(IMHO).  I may upgrade my Parasound A21 to the M2 at some point.
Just to add, as I upgraded my Directstream dac firmware and Audirvana + software, the Herron easily transmits these improvements to the amp and speakers.  Sorry if blakcloud hasn't experienced an improvement.  
Keith Herron describes the VTSP-360 as both fuller and more detailed than the VTSP-3A (r03) and that seems right, though I don’t have them side by side for comparison.
