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.

Tube like is a dubious term...some tube amps are great some not so much. Same is true for solid state and many other items. Tesla P100 range with a very heavy foot and winter weather is well under 100 miles...no one tells you that upfront!  You need to be able to use and enjoy what your have. I have a complete Krell system Evo 202,525av, 600 monos, lat 1s, vanguard with dac without amp using transparent reference cables and couldn’t be happier unless work allowed more time to use it and volume setting 7 out of 151 didn’t give my wife a migraine in a 6600 sq ft home. Would I buy it again no! It is complete overkill and useless in my home or outside a recording studio. The rare moments I can enjoy it are few and far between but very satisfying. Even the cabinet had to be custom...needed burl wood to match grass cloth wallpaper, be able to support hundreds of pounds of items and complex cooling system to deal with heat as well as custom electrical outlets to offer isolated ground with 20a individual circuits for nearly each item.  

At at least it looks great and will most likely end up in my office. 
The Krell would be the easy winner here.
+1 for the Krell, and it will drive anything now, or later you hook it up to.

I have used Krell Integrated amps for over 15 years in my two main stereo systems ( Krell KAV 400 xi and Krell S 550i). I have pushed Maggie’s with both integrated amps just fine and Maggies have to be the most inefficient speakers built. The sound I get is amazing - midrange, bass and imaging are the best I have heard. Just be aware Class A power runs hot! But it sounds great. Krell service was needed on my 550i and they were great! Go with Krell and you will be happy! I am!
I own the latest Krell Duo 300 XD and couldn’t be happier. I have owned the iconic 400 FPB and other Krell classics. This sounds the BEST. The latest series of KRELL XD amps are without question the best sounding amps on the market for the money. A thing of beauty given the relatively lower amount of power the amp consumes as a result of some brilliant software. Pure class A power has to be heard to be believed. 
I own the Krell 575  monoblocks, upgraded to XD. I can’t be happier with their new sound. Too, Krell’s customer service is amongst the best in the industry.
