Warm Sounding Speakers

I set aside my Krell 300Si integrated amp (150WPC - 8ohms, 300wpc - 4 ohms) in favor of more power for my Maggie 3.6's.

I liked the Krell but did think that it was a bit sterile sounding.

My thought is that it might sound better with warmer sounding speakers.

I iam interested in suggestions of speakers that might mate well with the Krell.

Please and thanks!
