Help me make sense of this.
Your Quad is going on thirty years old. In it's day, it was a very good amp. Nowdays, it will have a hard time sounding as "musical" in comparison a lot of "mid-fi" gear. No doubt- you are hearing a lot of definition that you've been missing. Ther... 
Lack of depth problem
I should have mentioned in my previous post that there are two tests that will aid you specifically in the placement of your speakers(on the Chesky disc). The LEDR, explained here: (http://www.stereophile.com/features/772/index.html) and the "Acou... 
Lack of depth problem
What are you driving them with? There are a lot of amps that allow no sound stage depth(few SS amps will). My Cary monoblocks will, and that depth increases dramically with the right driver tubes. There are more variables than just the speakers. L... 
Amplifier for Avantgarde Duos
Hi Chris- Since I know you are at least contemplating a switch to a 300B based amp- Here is a link to a review of 11 different iterations/brands. You may find the observations/info helpful: (http://www.stereophile.com/features/229/index.html) 
Discount on cartridges vs. other equipment
I was(starting in the late 70's), and was closely associated with the industry before that. I never stocked any of the MM's I mentioned, though I would order anything a customer might want. I usually tried to move at least a Sonus Gold(for the sak... 
Power conditioner or not?
If you are using AC to power your equipment: There IS noise/interference from everything online between your house and the generating station coming in with your voltage. That's just a fact of life. Once that goes through your system, it will eith... 
Discount on cartridges vs. other equipment
It used to be that the dealers were getting Shure, Pickering, Audio-Technica, Stanton and Ortofon MM Cartridges, that listed for 50 to 80 dollars for 5 to 10 Dollars each. Vinyl was THE way to listen to music, and the companies were putting out ch... 
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!! 
Anyone rolled tubes in an ARC Reference 3 preamp?
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.
