No it never really ends...
I can try to give a few pointers but you have to excuse my broken English.
First I have to say that my system has changed completely. I used my older floorstanders with the Decware MiniTori, a 4 w/c pentode amp. This new setup has the Decware Zen mono amps (2.7 watts/channel) which are pretty different amps . In terms of source I haven't been able to use my phono amp because of one tube with issues, a ringing noise, and my DAC is not top notch. So a fair comparison isn't completely possible. Also, both amps and speakers are so new that they still evolving, almost from day to day.
These HO speakers are a equipped with better drivers, they are faster and more detailed than the ones I was used to, probably in every aspect. Muscians are more present in the room, and seems closer to my listening position. Because of the second driver there is more detail and texture especially in the mid bass area. I'm not a bassjunkie, and I get more bass with the HO, but I wonder if the larger cabinet I have with the 7" Alnico makes the difference smaller than what could be. I really enjoy the added punch they present. Again, the dustcap driver have less than 40 hours of use and will develop plenty over the next 100-200 hours. So I might find bigger differences when they mature.
Instruments are easier to tell from another, and the way a sound stays in the room, from a guitar string or an accord in a piano is better with this new speakers. I believe I have more headroom with these speakers, haven't pushed the amps to clipping yet, but in my mind if you want a hairdryer volume you have gone the wrong way a low power SET amp and FR drivers. They play loud enough for most occasions, and then some.
I seem to find both a wider and deeper soundstage, maybe because of amps and also because of the speakers. The detail in background are very in background but still it is easier to follow just what goes on there.
I have to say though that both speakers are very very good. Because of circumstances I got an opportunity to try this new solution and there is no doubt this is a better speaker, but I would be very happy with the original speaker I have had for 3 years or so, but no going back now..
