Warm Sounding Speakers

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.

Dorgay's review is here.

The current Bose Series VI has been around for 25 years. I wonder how good the design could be today with the better full range 4" drivers available today, say with neodymium magnets, composite cones, cast frames, phase plugs, and high excursion surrounds, plus an active crossover with higher quality parts.

Then put them at the proper height on solid, rigid stands such as Dorgay used.

It *does* have some things going for it, such as crossoverless design and uniform power response.

Dsper, if you haven't already done so, I suggest doing a Google search on past online reviews that have been posted on the Krell 300si to see if any of them talk about specific speakers that mate well from the perspective of warmth.

Warm sound will almost always require tubes, but I love all the Sonus Faber speakers I have owned (which is about 4 different models over the years). Still currently using the Sonus Faber Cremona. Not sure how it would sound with your Krell.
