Upgrade from Pass Labs XA30.8 to X250.8. Worth it?
A few months ago I listened to both (250 & 30.8) and some other amps driving a pair of Danish, not very sensitive, spkrs. Between the two, the 250.8 had much more driving authority but the 30.8 won on timbre and sound quality overall. If I rem...

Watts are watts?
Are tube watts really "stronger" than SS watts? Of course not, the differences lie in how the two types of amps operate and, thereby, the application. Tubes are current source devices whereas SS amps are voltage source devices. What this means: ID... 
Preamp for Burmester power amp
Hi, nibongese, A few years ago I played around with your amp (or was it a previous model?) driving a pair of ATC scm50 (not my spkrs)—coincidence, eh!With the owner, we tried the following pres on loan from shop & friends. Cables were from Nor... 
News: Qobuz Hi-Res platform's debut is scheduled for this October. See Qobuz Links below
Qobuz is very good for classical, it even has a few vintage recordings in hi-res remasters.   
Filling speaker Stands?
Many use a combo of lead shot and sand Usually the best combo; if lead shot is too messy, you can survive with sand alone. You might also try blu-tacking the speakers onto the stands as well (instead of the Sorbothane) & check for improvement... 
Vandersteen 1 repair.
Madisound responded to email and inform me that they think there is a Seas driver that should be pretty much an exact replacement. Can you say which SEAS driver? (Writing Madisound was the right thing to do, of course!). I'm guessing matching u... 
tima's DIY RCM - follow-up #2
Interesting article, thank you for sharing. 
Vandersteen 1 repair.
" Part of me feels like being daring and looking for a pair of drivers to use that may equal or possibly improve performance " Why not, after all, adventures can have happy endings (albeit, woofers can be expensive off the shelf!).  The only drawb... 
Value of burn/break in?
Speaker placement is fundamental to good sound (as is the speakers' dispersion pattern-but we can't change that!). I suggest you try the following: measure room width and place the spkrs at ~45% of that width from the back (i.e. behind them) wall ... 
HiRez to Redbook
May I recommend you NOT down-convert them? Just play the music 24/96 through your mac using Audirvana or any other music player of yr choice. The difference between 24/96-192 & 16/44.1 is not subtle. If you must, then most media players will d... 
Revel Salon 1 still worth it? Possible a small room?
I listened to Salons with a friend in a room not much bigger than yours and the result was depressingly below par: poor mid-bass, anaemic bass, pronounced upper mids and hi-frequencies, unconvincing mid-range... We tried placement along the long w... 
Tidal streaming and classical music
I second the Qobuz option. Not as many titles as Tidal overall, but definitely more (and intersting) classical. 
WHAT HAS WORKED FOR YOU? ISOLATION PLATFORMS, FOOTERS, ETC. for a DAC?
I have a relatively heavy DAC that is very sensitive to treatment (Ayazi) and after extensive testing with cones, stillpoints, etc, I finally ended up with 2 magnetic levitation (maglev) & one alu cone. The one maglev is under the transformer,... 
Avalon Isis or Sonus Faber Liliam
Judging by your brief description alone, I would say stick to the Isis. The SF would probably be slightly more pronounced in the high frequencies and, while quick & dynamic enough, they would not be appreciably more so than your Isis; nor woul...
