I have had both at the same time, and sold the Reeves mostly because of the similarities.
They are both great amps, and are quite comparable. I prefer the original's tone, but that's primary due to the head having original valves though.
Been playing Hiwatt for over 35 years, and am a real fan. My '71 DR103 is my all-time fave.
As for the Partridge transformers giving a Hiwatt its tone... that's simply not true. Many prefer the Drakes, as did Harry Joyce.
The Hiwatt "magic" is in the tone stack. The combination of the Hiwatt's frequency range [(-3db) 3.6 hz - 112 khz], and the dual input/EQ is what sets them apart from other amps. They're not voiced for any particular instrument, they work well with guitar, bass, keys or whatever. That is why they are labelled "AP", which means All-Purpose.
I believe you would enjoy either the Reeves or an original... whichever suits your budget will do.
Good luck in your search.
