Used integrated around 1K for very forward speaker

Hi,

I would like recommendations for a used integrated amp, which would mate well with my Onix Ref1 speakers. These are very forward and resolving 4 ohm speakers. I guess I would want a warm amp to balance things out, right?

Any recommendations are welcome.

I would prefer an amp with an HT bypass, so I can use my main speakers for both 2 channel, and HT.

Thanks,
