Ditch the the lower octaves of bass, and let the 300b drive a medium efficiency speaker of your choice from 125-150 hz. On up. Do this by using a 4th order active xover unit, and subwoofer. I used a 300b amp with 89 db. Infinity Qb's with ribbon tweeters, and cut off everything from 150 hz. On down from the 300b. A Hsu subwoofer took over the bass from 150 hz. On down to about 30hz. It was amazing sounding. Relieving the 300b of producing low bass, allowed it to play at a reasonable volume, cleanly. Would probably sound even better with some better 88-90 db. Bookshelves of your choice, but the Infinitys and 300b filled the room wall to wall and front to back with "your are there experience." Etched in my brain is a day listening to so called "ambient music" with this. At one point in the "song", My room became the Amazon jungle, and I was surrounded by jungle noises, bird calls etc. A very ethereal experience, and no, I wasn't tripping or on drugs.
Speaker Suggestions for 300b SET Amp
I built an Elekit 8600 300b set amp recently. It's amazing. I maxed out upgrades (all Takman resistors, Mundorf top end caps, solder/wiring, etc.). It's a wonderful amp. It cost me $2k to build it and it's glorious.
My issue hasn't been the amp, but finding speakers that I want to use with it.
I started with Omega XRS 8 Juniors (~$2k). I broke them in for 300 hours and, while they did get better, they largely sounded like the top and bottom ends were just truncated off at both ends the sound spectrum. They sounded more akin to a transistor radio speaker. I feel terrible to say that and I hope others really love them and hear them differently, as the company is great and the owner is wonderful. They just weren't for me.
So, I just paired the 300b up with some inefficient speakers (both KEF LS50s and Wharfedale 80th anniversary Dentons). Both speakers were part of other systems I have. Both sets, and especially the cheaper Wharfedales, just sing with the 300b. They do not play particularly loud given their efficiency ratings, yet they sound wonderful for very close nearfield listening.
But what I'd like to do is go a bit more into the full range speaker category without buying a massive product. Or, I consider a smaller bookshelf/monitor if it were more efficient.
What speakers do folks like with their 300bs?
