Are marantz power amps any good?

In the mid to late 90s, I had the pleasure of owning 4ea of the MA-22 class AB mono power amps.  They were awesome.  I liked them so much, I later upgraded them to 4ea of the MA-24 which were 30w class A units.  These sounded very good but truth be told, while I loved the physical design the MA-22 units actually sounded somewhat better driving my bi-amped Martin Logan Quests.

Just for lindisfarne...........whatcha gon be drivin wit dis amp nesto?

Seriously what speakers are you using? 300 watts is a ton and there are many good amps both tube and ss in the 30-100 watt range that are very affordable. And as always it's not just about watts! Power supply, overall design, are factors that are just if not more important.

I will be driving monitor audio silver 8 (new model)

Well looking at the specs and reading a couple reviews they sound like nice speakers and fairly easy to drive 90db sensitivity and a nominal 4ohm impedance. So lots of options out there to choose from, both tube or ss,  do you have a budget in mind?
