I use the T+A PA2500R, which uses much of the same tech as the HV range. A much overlooked amplifier in the UK!
You would certainly enjoy a vast increase in power, amongst much else. Not directed at you, but I often read of people looking for amps properly to control their speakers, yet no mention of T+A. Mine is rated at 140W in to 8 ohms, 280W in to 4 ohms and 560W in to 2 ohms! Very few amps can achieve that.
This power is lost on my speakers, which are 92db/w/m sensitivity, so I doubt I ever use much more than a couple of watts! However, the amp is capable of amazing resolution and control, without being sterile in any way. Neutral presentation, certainly not warm, so be aware of that. It will easily fully allow your source to shine through. The space between instruments is astonishing. It also has much of the delicacy of valves.
Build quality is e exemplary. Attention to design detail abounds. Connectivity and flexibility is first rate. Excellent display and the volume works well (no simple pot here). Adjustable and defeatable tone controls; you can even adjust tone by channel! Adjustable and defeatable loudness control as well, which can be useful for low level lustening.
Two sets of speaker outputs, separately controlled.
I've heard a Gryphon Diablo 120; the PA2500R is quite similar in SQ, imo, but it's smaller and lighter (weight is a critical factor for me). The T+A is quite a way away from the Pass Labs sound, particularly their Class A designs.

Let me know if you need any specific info.
