The Alexia is a tough load to control for a tube amp and while the MC2301's were sweet in detail and presentation of mid & upper ranges, they had trouble gripping authoritative control over the lower bass modules. I loved those amplifiers but after I heard what the Alexia's do sound like with an amplifier with "many more trouncing watts" on tap, I was sold.
The Dan D'Agostino Progression amplifiers not only have that wallop (up to 2,000 watts @ 2 ohms) as they say, they also fill in nicely with the strengths of the MC2301's; very quiet, intricate, refined and highly detailed with a slightly quicker pace; yet not fatiguing.
After nearly 10 years with the MC2301's, I'm really happy with the change I made and these will be around for another 10 years or longer (I won't be able to move them the older I get  ).
Best Sir,
Bob
