Attention Horn Owners

You really need to get some seat time and not just a quick demo- listen to a variety of material. I made the transition from decades of electrostats to a horn type (Avantgarde) in around 2006. Very revealing of what's up-chain, not just noise, grounding anomalies, etc. but you will hear significant differences in tube rolling as well as other changes in the system. Get it right and they can be marvelous. It took me time to "evolve" this system- from amp changes to line stage and phono stages to cartridge changes. All got me closer to my ideal. I do add bass reinforcement as part of this. 

NY metro used to be one of the centers of hi-fi in the US if not the world. I lived there for decades. Well worth visiting a few dealers and if you can find them, system owners (as you have posted). I'm in Austin now, so can't help you out but if you are willing to put in the time before you buy, you'll spend your money more wisely in my estimation. Have fun!

I think you’ve gotten some good input, @earthbound and have not heard the Volti, agree that the bass on the Duo (at least my era, perhaps later too) was difficult, and was only solved by adding 15" subs with the system in a different, larger room (I moved) and DSP’ing them in addition to dialing them in and changing cartridges to something with much more bass gravitas (a Koetsu stone, which does bass in a much more filled-in, dimensional way than previous high-end cartridges in the same table/arm), but my main point to underscore here-- and something I did not mention but which @larryi did-- is the ability to use SET amps if the speakers are really high efficiency. One of the first steps in getting my Avantgardes to come closer to the sound of real musical instruments was to switch the amps to Lamm ML2s-- that was a big step and made possible because of the sensitivity of horns. 

Apologies to @sns, who also mentioned this by tube type.
