Again the topic of weight of amps

Tim, I said the RM-200 is "really nothing special"? Au contraire! There is much more to the amp than what I wrote above, as a reading of the review by Fremer and Atkinson in Stereophile will illuminate. The "sales pitch" crack was made in reference to past comments by someone (I don't hold grudges, he's entitled to his opinion) about my too often mentioning of the amp. I like to bring to peoples attention over-looked products, like the Eminent Technology LFT-8b loudspeaker, another tremendous bargain.

@fleschler I weigh 182lbs, lol, and my wooden floor, with substantial joists, supports me. My upright piano weighs 500lbs, and there is no problem with it either.

I don’t think stereo components weighing a few hundred pounds are a problem for most structures.

mitch2,

     Thank you very much for your interesting and informative responses.  Your, and some reviewers, mentioning the whole issue of truncated bass notes on some class D amps was new to me. After rethinking my experiences with multiple class D amps in my system, however, I completely understand this perception and believe the exceptionally high damping factors of class D amps may be the culprit.  In retrospect, I certainly never heard my Magnepan 2.7QR produce the type of bass that they did when powered solely by my very high powered class D mono-blocks with damping factors >1,000.  I remember enjoying the tight bass but have to now agree it sounded a bit tauter than natural bass heard live.
     Good luck with your new amp rebuilds.

Thanks,
  Tim

@larrykell  I said that I couldn't physically handle a 185 lb. amp.  My current listening room floor can handle a 7.5+ earthquake let alone a few hundred pounds of equipment.

My 1993 constructed prior home had a similar custom 6" slab with 2' exterior footings, 1' interior footings, 8" plate with 6" staggered studs every 8"- no damage from the 1994 6.9 Northridge earthquake. 

@fleschler I guess I misunderstood you and thought you said we should be worried that a floor couldn’t hold that kind of weight.

I put my Gryphon on those little felt furniture pads so that I can slide it around. It doesn’t get moved often but I can slide it a few feet, or across the room, by myself.

When I needed to get the amp moved, I paid my building guys to help move the thing. That’s an advantage to living in New York City. Yes, it’s a pain to move such a heavy amp, but I hope to never have to do that again. It’s a lifetime amp for me, one I expect to keep for decades.

I’m glad you live in a solid structure in California. I never could get used to earthquakes and I went through two small ones when living in LA. I guess I’ll take my chances with hurricanes over earthquakes. It’s always something.
