Devor - KEF - Vienna Acoustic – Wilson?
Quad 2912 for ultimate clarity or Harbeth M40.2 for more dynamics. But at this price there are many options, and nobody can hear them all, let alone compare them directly and in your own home.

Have a powerpoint screen with: this sucks 
Streaming vs traditional
Well, the comparison was between high resolution (i.e. 24/96) files and MQA, and (rightly or wrongly - there may be a discussion about the test design) the result was that there were no sonic differences. If true, this allows us to conclude that M... 
Streaming vs traditional
Of course I listen as well. However, sighted listening tests are methodologically deeply problematic because there is potentially so much expectation bias. The blind test that I linked to suggests that there is little or on sonic difference betwee...

Really? 
Are future improvements in Amp/PreAmps slowing to a crawl?
See here for a nice video of a proper listening test that shows the methodology that is required:https://vimeo.com/137001237With some background discussion here: http://www.harbeth.co.uk/usergroup/forum/the-science-of-audio/the-ground-rules-of-pro... 
Quad ESL 57 playing Prince
But beware: max peak voltage is 33 Volt, and the amplifier has to be unconditionally stable, also under capacitive load. These are speakers that have been known to destroy amplifiers, and some amplifiers have been known to destroy these speakers. ... 
Harbeth P3's or CS7 easier drive
As for the Leben, see here for the test results: https://www.stereophile.com/content/leben-cs300-integrated-amplifier-measurementsEven though Harbeths are easy to drive, this load dependent frequency response implies that the amplifier is by no me... 
Harbeth P3's or CS7 easier drive
The P3ESR is a closed system and less efficient than the bigger models. So it needs more power for the same sound pressure (about twice as much). At the same time the driver is rather smaller so it cannot handle as much power. Remember, however, t...

Spotify is apparently planning to follow Qobuz and move up to 16/44, the cd red book standard. That is not high resolution by most people's standard, but it is enough for me. I am not convinced that anything more is actually audible (there are cla... 
Subwoofer advice please
I did once (1976) hear stacked 57s and that was impressive. However, with the later designs this is indeed not a good idea. Instead, if one wants to stay with stats only, the solution would be to go for the bigger 6 panel models (they are not even...

I have had ELS57s from 1977 (only quite recently replaced them by 2805s) and never did any harm to them. As it says in the manual, it is important to prevent higher voltages reaching them, so I never used any other amplifier than the Quad 303 that... 
PrimaLuna Dialogue Premium Preamplifier. DESTROYS SPEAKERS!!
I am not interpreting, let alone judging (and certainly not judging about place of manufacture). I am only offering the information that this is another case of a nasty failure that on the face of it may have a similar origin. And even if the fina... 
Looking to completely overhaul my preamp section, knowledgeable people needed!
What sources? If only digital there is the Pioneer U 05 or for rather more money the Benchmark. Even more money would buy the forthcoming DSpeaker X4 with a range of equalization options.
