Reviews:

1. Paul Vnuk - Recording Magazine: "This is essentially the third time I have reviewed this preamp, and I must also disclose that I own and have been using an 8-Channel HV-3D for well over 12 years now...it’s a sound I know well and really appreciate. Everything that I used to describe the HV-3 sound above holds true to these new HV-P models, and while there are some spec differences between the older HV-3 and these, my ears cannot detect a difference..."

2. Randy Poole - Pro Audio Review: "The HV-35 was consistently in my top two for all tests with the Radial Workhorse chassis. In comparison to transformer-based Class-A designs, it was more open on the top with less compression of transients and a more detailed sense of ambience and space. Compared to some of my favorite tube-based pres, the HV-35’s low end was punchier and thicker. The HV-35’s high end was accurate and pleasing, while in comparison the tube pre’s additive harmonics and softening of transients felt quite flattering on acoustic guitar. Overall, the timbre of the HV-35 was more balanced than all of its tested counterparts, and its placement in the stereo field was more “three-dimensional."
