All else being equal.............................

Since i'm not a fan of Krell's latest offerings, I would lean toward the Hegel. Bare in mind that i've read commentary on here & on other sites reporting there is a difference in sound between the H200 & H300, and some owners on here prefer the sound of the H200. Unless you need the H300's included dac or digital inputs, I would suggest reading up on threads here discussing the two amps. Here is one example.

With the above said, if you're open minded about other potential options it would be helpful to know you budget, accompanying equipment (amps, speakers & cables) and approximate room dimensions so members can offer more appropriate advice.

Fla, that might be over his budget. He could look at a Dealer ex demo Aesthetix Atlas Signature tube hybrid amp & Janus Signature pre. That is a nice combo & would be good value. Otherwise a 2nd hand Vitus RI-100 is an awesome ss integrated and has excellent power.
