Kenny, it is a new sound for you after a bit of time off from 2a3’s. If you were to listen to the 2a3 only for say two years and then pop in a more powerful OTL etc.., then you would be equally pleased and excited about what that new sonic flavor brings that you have been missing. It’s just the way it goes with great amps of different sonic flavors. Great OTLs, SET DHTs, PP EL34s, Class A SS, Class D, Hybrids ( I love these), all bring a slightly different sonic flavor that can certainly please us greatly for long periods of time. Make a change to a new amp and enjoy a whole new flavor with all of the freshness and excitement that goes with that. All our favorite music now delivers a slightly different experience, that if in our enjoyment zone, becomes a new musical high!
The key is the new amp must be in our wheelhouse of musical enjoyment. Some have a smaller wheelhouse, while others have a very wide wheelhouse. Many fall in between.
I have no doubt the 2a3 amp is fantastic, I owned two, but one cannot dismiss the role "new" plays to our ears with the above caveat.
This is not true of women, or more specifically, our spouses. Only one best for life with no other options even looking good. 😀
