Warm Sounding Speakers

Tannoy get the prestige series add a super tweeter.
Kef are warmish but it depends very much on the model these days.
Big Vandersteens.
Quads (very polite not terribly dynamic)
and the Harbeths which I find very warm and not my style of speaker but you might.
Ditch the Krells and get the New Carver Monoblocks with new or old style tube sound. The old style may be what you want.
OK I am ready -flame away. I personally like detailed speakers and modern tube sound.

Warm speakers include Silverline Sonata and Bolero, Dali Grand, Vienna Accoustics and while they are expensive - Soundlab speakers.

Bose 901 might work for you. They sound a lot like Maggies and you can dial in the sound with the dedicated EQ.

That's a hoot !!!!

Tpreaves, Read Jeff Dorgay's review in Tone Audio on the Bose 901. Google Tone Audio to read the entire review. It is interesting.

I owned the 901s back in the 80s. After reading Jeff's review I feel vindicated for liking them.
Actually, I do think Jeff nailed it in his review.
