Tube tester recommendations
Samhar- The Amperex tubes(whatever family) are always a reliable choice. If you enjoy focus, dynamics, ambience retrieval, grainless highs, transparency and extension in both directions w/o bloat or sibilance: try the upper-crust of the Siemens 69... 
Valid Efficiency Test?
Are the filters going before or after the amps? If before(like they should): It won't make any difference to the speaker's efficiency measurement, because that's based on 1W(or 2.83v) output from the amp. You don't measure from the speaker to your... 
I walked into a dealer and got a shock....
It's one of the peculiarities common to our species, that we are always relying on "experts" to tell us what we should like. Moreover: We rely on the same "experts" to TELL US whether or not they ARE "experts." 
Tube tester recommendations
That Amplitrex unit actually tests at full voltage levels, which gives me much more confidence in a diagnostic than partial voltages. I like the digital mutual conductance readout too. The Hickok tube testers have always been highly regarded, and ... 
Anyone rolled tubes in an ARC Reference 3 preamp?
Everyone has different goals, ears and systems. Some systems won't resolve the differences between cables, tubes, etc, and some can't hear, or perhaps don't know how to listen to the various changes that component swaps can make. I've got some Ken... 
best output tubes for jolida 502b
I've always used NOS tubes, but when I wanted to replace the eight matched 6550s in my Cary mono-blocks, I almost went apoplectic! The prices have gone nuts on matched quads/octets of anything worth having(supply and demand strikes again). To my s... 
Can a 5z4 tube be a metal bottle?
Enjoy your music!!

Hate to rain on anyone's parade, but you CAN "roll" the vanilla 6H30's for these: (http://thetubestore.com/russian6h30pdr.html) There are a couple other versions, but that's the hot-rod of this small family right now. 
Interconnects with smooth highs 4 Manley Stingray
You should be able to find a pair of the KS1030's(.5m)for that. You might have to be patient(may not be a lot out there, as that's kinda short). Here's a pair for sale that's slightly longer(24"): (http://www.audioweb.com/P/PInfo.asp?pid=34444) I'...

Can a 5z4 tube be a metal bottle?
People generally lump all the 5Z4, 5Z4G, 5Z4GT tubes together with the equivalent replacements (the CVs/GZ30). Mullard drop in equivalents are common:(https://www.tubeworld.com/5z3.htm) (http://cgi.ebay.com/Mullard-NOS-GZ30-5Z4GT-Orig-Gov-Box-Mull... 
Burning in a new DAC
The voltages will be constant with a disc/pink/brown/white noise, while with music- it varies widely. A constant higher level will help the dielectrics form their charge faster, thus reducing the necessary time somewhat. Figure two hundred hours f... 
Can pro amps possibly sound good? Crown, QSC, etc
If a piece of "pro" gear meets your criteria for "good", fly with it! I've been using a Hafler TransNova 9505 to bi-amp my woofers with for years. It's a "pro" studio amp(though not a particlarly inexpensive one), and I couldn't be happier with it... 
Question about set amps and low sensitivity spkrs
No real mistake was made. You wanted, and found an SET amp. You already knew you'd need more efficient speakers to go with it. You'll be able to listen to what you have until you get the new speakers. As long as you are building your system based ...
