When I had the Premier 11 I once heard two Premier 8's and was smitten - but they were beyond my means.
Later I switched to Berning and was equally smitten, but in a different direction. This is an amp, I hold in very high esteem.
When I heard the LP 140, it did not move my heart at all, but maybe i simply had moved on. (And the LP140 has a questionable quality reputation here in Switzerland)
I have to admit, that was unlike me based on, albeit well sourced but still: hearsay. I'll try and amend that, not least as my Prem 11A was flawless for many years as well!
