Millercarbon quite the opinionated chump.
relatively low cost good quality good sounding units to try - if you don't like you won't lose much, if anything, reselling
Have you considered DIY? My current system consists of a Bottlehead BeePre 300B tube preamp with a Bottlehead Kaiju 300B power amp. This SET combo provides 8 watts, which would be fine with your high efficiency Heresy speakers. Bottlehead provides great instructions and tech support, which essentially guarantees a successful build experience. I really enjoy the sound, and with your budget you could also build a Bottlehead Eros 2, a really great upgrade to your phono preamplifier.
For ready built gear another company I would recommend that you consider is PrimaLuna. For under $5K you could get one of their higher end integrateds or go for separates. The PrimaLuna amps are based on the sweet sounding EL34 tube and would provide more power over the SET setup above, opening more options for speakers should you decide to upgrade those in the future. I owned a PrimaLuna Evo 300 and was quite pleased with it until I got into SET and DIY.
