Informed/Insightful information requested on Tannoy GRF loudspeakers
Nice, you've already got lots of tubes; Tannoys will like that :) Lots and lots of KT120 is a particular favorite of mine; yep 16 will do it!  For what it's worth the Prestige cabinets have been built in a Polish factory for many years, not Scotl... 
Informed/Insightful information requested on Tannoy GRF loudspeakers
That said, if I'm in your shoes with that money, I'd probably wait until one of the following models pops up for a good deal, from a seller that can pack & ship them properly via freight (e.g. TMR): Canterbury SE or GR - Preferable but usua... 
Informed/Insightful information requested on Tannoy GRF loudspeakers
I think you posted this question on the Tannoy FB forum. Anyways, just be aware the GRF90 is a little different than the Prestige models above & below it. It has rear reflex porting, which makes for amazing bass output, but perhaps at the slig... 
Is it better to get dedicated monoblocks instead of bridging stereo paired amps?
Bridging two SS stereo amplifiers to mono is usually NOT a good trade-off for the massive power gained - up to 4x power for amps that "double down" i.e. high current. Why 4x power and not 2x? Because bridging doubles the output voltage which also ... 
I replaced the volume pot on my tube preamplifier.
I was going by the label on top that shows 50KA X 2 @mashif That’s a specification - 50,000 ohm input impedance, x2 for stereo (2 gang) - not a model number. If you were looking at an RK50 model you’d think "wow!" - it’s massive, shiny, beauti... 
I replaced the volume pot on my tube preamplifier.
After reading this post, i checked the motorized volume pot on my LTA MZ2 and it appears to be the RK50A. And it's well under $10k.  The only MZ2 pics I see online clearly show an RK27 - some motorized, some not. An RK50 wouldn't even fit in th... 
I replaced the volume pot on my tube preamplifier.
@mulveling  It’s certainly an eye-opener for sure. Most manufacturers are component lazy, compromising their product sonically and economically.  Agree! I’m normally a fan of "affordable, but reliable and sounds good" parts (like resistors, cap... 
I replaced the volume pot on my tube preamplifier.
The Alps "Blue Velvet" RK27 is almost ubiquitous in analog preamps and headphone amps below $10K - especially tube units which are less likely to use a digital volume chip. Which is a shame, because EVERY TIME I’ve compared this pot to a better al... 
SonarQuest Silver Plugs have Nickel Layer?
I’m surprised they volunteered that, but then these are pretty affordable as far as premium connectors go, these days. They’ll probably say the layer is so thin (e.g. a few atoms thick) that it doesn’t affect sound nor electrical resistance, and h... 
Splitting line level out from preamp, versus using 2nd set of outputs
That should be fine. It’s hard to imagine the extra connection point and IC would penalize this enough to notice, unless psychological.  So you’re using 3 sets of ICs to ensure symmetry between the 2 paths. That’s perfectly fine, but if it were m... 
Why most $3000 and lower DAC’s sound almost identical
The ringing you refer to above is in the time domain. It happens at the cut off frequency. It only occurs on signals that exceed the Nyquist frequency. Properly produced music should not have transients above 21 KHz. It’s actually a non issue and... 
??? How Do You Determine How Far You Can Take An Amp When Choosing Speakers ???
"Weakest link" and "source first" philosophies (etc) belie the nuanced complexities of human perception and system building. Though when you’re starting out, it can help to establish a sense of order amongst the chaos. You can have great successe... 
Why most $3000 and lower DAC’s sound almost identical
Isn’t eliminating the “pre echo” exactly what Meridian’s apodising filters (circa 2008) were designed to eliminate? Not mitigate, eliminate - at the expense of higher artifacts on the post side. I also thought that has been largely replicated now ... 
Tin Pan Alley and Thanks to You- which speakers play the tap on the snares the best?
 My Tannoy Canterbury’s with a pair REL 12” subs, goose bumps  experience whenever I cue up MFSL UltraDisc One-Step 45rpm Vinyl :-)  @lalitk I’ve been tangentially interested in subs for my Tannoys for a while, but still haven’t done it yet. Ho... 
Grade Master3 cartridge--Moving Iron Design
Peter Ledermann has admitted he only makes low output MI cartridges so that buyers can use their expensive MC phono stages with them. That’s a really interesting point, in favor of high-output MI (and MM). Since there’s NO moving mass penalty w...
