Advice on Krell amplifier


I am planning to replace my 20 plus year old Audio Research amplifier with a solid state one (tired of dealing with tubes). I’m considering the McIntosh Mc312 and the Krell duo 175xd.  The Krell is highly recommended by a trusted dealer as having a “tube like” sound and going well with my other components.   My other equipment: Audio Research preamp and phono stage (which I plan to keep) KEF Reference 5 speakers, Innuous Zenith 3 server. I haven’t seen many comments or reviews of either the McIntosh or the Krell. I would appreciate any advice, including comments from people who have heard these amplifiers. Thanks.

I would have thought the dealer would have also recommended the Coda # 8 for the KEF Reference 5's.
Yyz-good suggestion. Actually, the Coda was recommended also but the Krell got even a higher recommendation. I haven’t heard or even seen either amp but was told that, while the Coda is very good and costs less, the Krell was even better particularly if looking for a tube like sound.  Any feedback?
