I had four of them at the same time to compare in my system. The aesthetics Rea signature with a premium tube set, the Herron, the zesto and a cheap antique sound labs.
First was the herron. Everything was just right.
Second was the zesto. Very nice but a more distant presentation and slightly more polite.
Third was the cheap ASL. Immediate and impactful but could be a tad harsh on the highs. I should mention that it was heavily modded.
Fourth was the rhea signature. Compared with the others it didn't have the detail and wasn't involving. I was shocked as it was double the price of the others. Tried both sets of tubes but no great improvement.
If if I were the op I would call herron. Sometimes he gets trade ins that he refurbs. If you get anything different you're just going to be looking at upgrades again in the future. It is one of the few components that I don't even think about changing anymore
