@bouncehit: Congrats on your new amplifier find.
There are lots of VTV Hypex versions on VTV’s website. Which one (if stereo), or ones (if mono) are you using? Did you stick with what you originally received, or after the “dialing-in”, did you stick with that configuration — i.e., exactly what amplifier, and op amp configuration is working for you?
Have you compared your SoundLab Ultimate PX’s and the VTV’s with other solid state push-pull, or Class A amps, or Tube amps? If so, it would be beneficial if you were to cite and discuss your comparative experiences. Thanks, -Mike
