Does carpet deaden the sound too much?

@rixthetrick, with a mcintosh mc602 with 600 watts per chanell i guess carpet would'nt matter in my case!

In my experience having my systems in 3 different rooms with different flooring throughout the years, the best sound comes from wood/tile floor with a thick rug in front of the speakers. A fully carpeted room sounds a bit dead but that can be resolved if diffusion is added to the ceiling and/or walls for balance. If the speakers are inherently bright then perhaps nothing is required to be done.

@g_nakamoto We were lent a pair of McIntosh MC501 with the matching pre for at least 12 months some years ago, while the development of a customer's pair of speakers was undertaken.
They sure had some drive, so yeah I'm thinking you're not going to lack energy in your room at all.

I have only got 400 Watts a side and I don't use even close to nearly all of it ever.

@hiendmmoe - have you any thoughts about the varying responses so far?
 

I also have plenty of LPs lining the side and rear walls.

I had speakers spiked on w2w carpet for many years. I just had carpet removed and hardwood floors refinish. I am now using Herbies Gliders with spiked speakers on the hardwood floors. It sounds more lively, open and detailed. I think its a big improvement. I am happy with the result.
