Maybe buying a different amp

You could be fine with the Hegel 190. But before any specifics, are you looking for new or used? 

For new, you could try out a lot of different models for 30 or 60 days for as much as the shipping cost.

OP,

Sorry traveling is out. From what you have said I would focus on Audio Research, Pass XA series, Krell or Conrad Johnson… you want a warmer presentation. 

Try an Orchard Audio Starkrimson. They are running an amp tour on another forum. Listen to the amp free for a week, then ship it to the next person. Sign up with email on the company website. I bought one after participating in the tour. Love it. 

Thanks,

Thanks @aldnorab.
