I realize “better” is subjective, but a speaker that does what Harbeth does, but better.
I have a set of Pass Labs XA100.5’s,
Sound quality wise, getting a harb 40 would be a waste of these Pass Lab amps, i.e., these are good amps.
20k for that Harb is broad daylight robbery of old men on social security. The Harbeth with its poor quality design/build at most is worth 1k or 2k. It really does not sound any better.
Get a Wharfedale Elysian
Or
Get a Mofi Sourcepoint 888 for 5k and pair it with those Pass amps....Both the Wharfedale and Mofi were designed by higher aptitude British guys, i.e., much higher aptitude than heritage Harb’s daddy and hence they tend to walk all over 20k Harbs.
