Attention Horn Owners

Any horn speaker with horn honk is ether not properly designed or improper setup and partnering equipment. Your AN speakers are very nice, they have some of these horn characteristics, great dynamics, big sound, sense of performers in room, musical, probably my favorite box speakers, and one of the good ones regardless of design. 

Horns will allow use of 300b, 2a3 or perhaps 45 tube amps, I do like Voltis, use his tractrix horns in my highly modified Khorns. Voltis are refined horns, they won't shout you out of the room.

You may find you'll want or need subs with the Volti's to get full impact of the lowest registers. Even with custom woofers and extremely careful and air tight seal my Khorns benefit from subs, two best for consistent in room response.

@earthbound I too would not be so quick to ditch the AN. Coincidentally, I just so happened to read an Art Dudley review of the AN-E Lexus Signature in Stereophile, May 2006 issue. Dudley loved them, I seem to recall some version of them was his reference for some time. Anyway always positive reviews of this speaker, and from what I've heard at audio shows they'd be a real contender for me. 

I also recently became a convert to the AN sound via recent purchase of Quest 300B monoblocks, I'm really impressed by the sound quality, I do believe the transformers in these really special.

I don't know if you've seen measured specs and/or reviews from Stereophile, but here is one account, https://www.stereophile.com/content/audio-note-e-lexus-signature-loudspeaker-audio-note-espe-he-august-2008 May, 2006 issue has specs on Lexus version, Atkinson measured 92.5db sensitivity, also stated, "I don't think the speaker will make significant demands for current on the partnering amplifier, which, in combination with the high sensitivity, makes it very suitable for use with flea-based single-ended amplifiers". Based on those specs and Atkinson's conclusions the 300B should work with the AN-E. I'd  try out some subs before concluding your not a SET guy. I'd also suggest REL's, they are unique in their designed to connect to high level connections on amp binding posts. I use two with my modded Khorns and they made all the difference, not just lower fundamentals in bass, but sound stage, imaging, better tonal balance as well. 

Now I did run Merlin VSM speakers some years ago, somewhat similar specs to the AN's, used those with both push pull and 845 SET amp, always preferred them with 845, bass much better than any EL34 and mids better than any KT series. Just for kicks tried them with some 2a3 monoblocks I had, no way, sounded like one of those pocket transistor radios. Of course 300B somewhere in the middle. I just wouldn't be so quick to get rid of what you have, your Aric audio amp and pre are fine pieces, almost pulled the trigger myself on his two enclosure 300B amps.

What 300B's are you running? The 'premium' tubes make all the difference. I originally ran the Shuguang Black Treasures, generally considered one of the best or best of the 'affordable' 300B. Then moved to Psvane Acme, wow, that woke up my custom build 300B monoblocks, just far more insight, micro, macro dynamics, then I move to the Western Electric, notable increase in transparency. Power tubes make a big difference in SET, the same with my 845 SET's.

I should also note since REL's designed to connect to speaker binding post, they take on sound characteristics of amp to some extent, most seamless integration of subs I've tired, this vs. far more powerful subs using dsp. Some speakers just need a little bit more oomph, reach in bass, these not like bookshelf speakers that need crossover set at higher freq. don't need these massive subs  My listening room 13'W x well over 30' L, I sometimes listen to electronic dance music and hard rock, my 'little' T9x pair of REL's do just fine, don't shake the room like my larger Genesis clone subs (Wyred4Sound), but the integration on all genres of music better.

From reading everything here, if it were me. I'd first try the sub route with present AN. If that didn't work I'd listen to Volti's, (and listening anytime is great idea) with your present amp and pre, try to demo in your listening room. Other horns are an option as well. And not sure I like your idea of going with Pass. I think Pass is great and all but fairly recently I purchased Pass XP-22 pre to have as backup or replacement for my Coincident Statement (DHT tube) pre. While it was nice, all tubes for horns is best IMO, just lost a bit of that presence of live musicians in room that is calling card of DHT and horns. Now some people don't like this presentation, they prefer more distance from the musicians, this upfront sort of presentation too much in face. I get it, I've heard other presentations that I quite like, I'd have multiple setups if I had the money and room.
