L220 Power: Macro Tech?

[58crewchief]

Just picked up some L220s. Long story short, the sound is fantastic. I am however, wondering if I am under powering them. I am currently running a JBL 6290 power amp. The sound is good but there is a fan. I've been intrigued by some of the more powerful Crown professional amps like the Macrotech 2400 or the even larger 3600vz. I would love to try out a macro reference or studio reference but from what I'm reading, I can get similar performance from the macro tech line for about half the price. Am I leaving anything on the table sticking with 300 W per channel? I know the macro line also has fans but if there is a sonic improvement to be had, I'd be up for a switch.

I ran mine for years with a Sansui G-9700 and thought it plenty. I don't recall, I think that was rated for around 200 wps.

58, as in B-58? Best looking plane in history.

+1. Sexy as hell! (And with four J79s in full AB, takeoffs must've been loud as hell too!)

Brochure says max recommended amplifier power 300wpc. Tech sheet says 400wpc. Often JBL recommends double that power for extra head-room. They also say 300 for the L150A and 450 for the L7. I run these with 200, though I have a Crown Studio Reference II I'll try on them someday when I have time and space: 355wpc at 8-ohms. :dont-know:

I've tried a Marco Tech amp and it doesn't sound bad at all, but the fan is seriously one of the loudest fans and it runs full speed all the time. They use a combination fan/transformer so there's no option to mod it and put in a quieter fan for home use.

I'm looking for an excuse to throw 600+ watts at these guys. Not too many fan-free options at these levels. I'm dealing with a fan right now but if I stay at this power level, I'm looking at Bryston 4b's and Hafler 9505's but they don't come around that much. The Macro seems like a good value but I can't abide a louder fan than the 6290. The Studio Reference has to have a less offensive fan...
