Roy Gregory has posted a review of the VTL S-400 Series II Reference stereo amplifier ($33,500) at The Audio Beat. His conclusions:
“Ultimately, all choices when it comes to audio equipment are personal, and part of the reason the S-400 II has left such a deep impression on me is that it dovetails so precisely with my musical demands. But then its very adaptability makes it that much more likely to dovetail with yours. This might not be VTL’s flagship amplifier, but its perfectly balanced blend of virtues versus price means that for a great many listeners and a great many systems it might just be the best amp VTL makes.”
