KEF LS50 Wireless -- wow!!!
I don't have any curious children roaming around, but I've considered designing some grills for the LS50. The only real challenge will be method of attachment, but I might have that figured out. My concern is how they might affect the imaging. 
Are my " diamond " tweeters really diamond
^ It's marketing, pure and simple. 
Full-sounding SS amps (besides Pass)
Yamaha's MOSFET based A-S1100/2100/3000.They have some tube-like bloom with great bottom end and realistic tone.  
Best Cd player or Transport for $1000.00 used.
Go on fleaBay and find one of the old Panasonic ShockWave portable players (like a Discman). They're battery powered of course, so no transformer noise. These will work just as well as any uber-expensive transport and you'll save $1970 to $2970.  
Mounting a Jelco Tonearm
I'd post this question on Audio Karma or Vinyl Engine, where there are larger DIY communities. I haven't mounted a Jelco, but have thoroughly read up on the process as it applies to Thorens tables. This is the first I've read of any discrepancies ... 
Are my " diamond " tweeters really diamond
The idea of using synthetic diamond is to use an extremely stiff material so that the resonance/breakup frequency is raised up higher than human hearing. I believe the breakup frequency of diamond is around 70khz. I think beryllium could be around... 
high-efficiency loudspeakers
I've found that a pair of recently acquired Klipsch Heresy IIIs are much better than I expected (not sure what I expected in my house, but I did force myself to listen to a pair at a dealer before before buying these damn things) and since many ha... 
Throughly disappointed with my new Yamaha A-3000 Integrated.......
@elevick That's complete bull. It's not his speakers, he simply received a defective unit. Yamaha integrateds are 2 ohm stable.  
Throughly disappointed with my new Yamaha A-3000 Integrated.......
The A-S3000 does seem to have a record of issues. Fortunately the 1100 and 2100 have better reliability. I doubt you'd lose much in sound quality by trading it for the A-S2100. 
how do you compare the hegel h80 to rogue sphinx v2???
@jmlab926 I'm saying the Rogue hybrid amps (Sphinx and Pharaoh) struggle with the lowest octaves. It's as though they have a sharp roll-off under ~40 Hz. I don't know if it has to do with their class D topology, but I haven't experienced this issu...

Keep the Hegel. Rogue Class D amps have no low end, especially at low volume.  
KEF LS50 Wireless -- wow!!!
Even the passive LS50s are leaps ahead of all B&W speakers I've heard. They  easily compete in the $4K standmount realm. Some say they're merely good, but I suspect they heard them with low quality amps. It's the trailing edges of notes, the "... 
KEF and Paradigm
^^ The KEFs will NOT require 300 watts to open up in a room that size, despite their low nominal impedance. That’s a complete load of rubbish. Efficiency is a combination of sensitivity and impedance.The phase angles matter more than the nominal i... 
Analog integrated amp recommendation
IME, the minimalist approach often pays zero dividends in sound quality 
Harbeth C7ES3 vs Spendor SP2/3R2
@vdotman I still have the SP2/3R2s. I agree with your assessment. Their bass isn't as punchy as I was accustomed to with other speakers, but as you noted, it's very natural. I now have them paired with a Yamaha integrated, a perfect match to my ea...
