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?

Thanks Ralph. If I get the chance to do an amp shootout for the PREs, you're on the list.

Having researched this issue myself now for quite a while, if I were running a SET and looking for good sounding HE speakers to match on a budget, that can play ANY kind of music well, Klipsch Heresy III, hands down, easy decision. These were originally designed for flea powered tubes amps of the day ~ 50 years ago and are still around (track record) and the latest versions I’ve heard sound wonderful, none of the bad things one often hears from audiophiles about high efficiency horns apply.  See the various online reviews for more evidence of this.

The throat and overall shape of the horn is essential to it working properly; these days computer modeling should have sorted out any anomalies that caused by past errors in this part of the design. Thus modern horns should be as smooth and revealing as any other speaker technology.

Mapman,
Interesting recommendation of the Klipsch Hersey. Wolf Garcia has waxed poetically on this forum about this speaker and how well it has mated with his low watt Had SEP amplifier. I tend to get the impression that it provides suitable refinement and tonality (I haven’t heard it).

It seems it would be a possible competitor to the Tekton Double Impact which I have heard with my SET amplifier. It was a very good sounding match. I can attest to the fact that it was easily driven by my 8 watt amplifier.

Charles I have only heard it so far at a dealer off a decent quality A/V receiver and was very impressed with that. These are very versatile and affordable speakers with a long and strong track record. The hifi magazine reviewers even seem to reach that same conclusion these days.

They are top contenders for next speaker to try with my 60 w/ch Class D digital amp. Their versatility to go different ways down the road as needed is a big plus.

I heard the double impacts at CAF last year off a very good quality 10 w/ch tube amp and liked what I heard. Those are much bigger with a different aesthetic and a bit more costly perhaps.

For bass extension, you might want to add a sub with Heresy whereas less likely with double impact.

However, large speakers with bass extension are usually much harder to get set up just right for best possible bass in many rooms. I tend to like the smaller speaker + sub approach better for that, especially when low power main amps are in play in larger rooms.  The Tekton room at CAF was not large, about the size of your typical Marriot hotel room.

Both very viable choices I would say. It all depends.
