Best Turntable/arm/cartridge system for $30k
I agree with Tom (as I already said) about not taking the plunge right away, but I do not agree with his suggestions, which, although excellent, are beyond what I would consider quality entry level ;-)I was thinking more along the lines of any com... 
rolling output tubes
I thought your question was about the possibility of substituting EL-34's for the KT-88's. 
Subwoofer setting
Before auditioning different lo-freq cut-off points (I recommend the 50Hz also) you should find a reasonably intelligent location for the sub. . . . . . Assuming you have only one sub (best IMO, as long as you can keep the x-over point below 100Hz... 
Best Turntable/arm/cartridge system for $30k
If you take away one zero, there might be some reasonable recommendations for specific units (complete, or separate TT, TA, cart,) but at $30K there are just TOO MANY great rigs you could put together!Not knowing your musical tastes (if specific) ... 
kt88 base temperature
Since you were tapping on the chassis, how do you know it is a power tube problem? Usually, microphonics develop in the gain/driver tubes (most often the smaller 9-pin twin triodes like 12 (AX,AT,AU) 7's, etc.Try tapping the top of each tube indiv... 
rolling output tubes
Sometimes, sometimes not (bias capability aside.) If you don't have a manual, or you do but that issue isn't THOROUGHLY covered, you MUST contact the manufacturer. Otherwise you're taking (unnecessary) chances ;-) 
What's next for the ultimate sound quality?
I second Brian's comments, and just want to add that you're an ACE woodcraftsman! (Where do you live? ;-) 
Mark Levinson 27 or 27.5 The Difference ???
The 27.5 is day and nite better than the 27ditto the 23.5 v the 23the 26s v the 26the 25s v the 25the 20.5 and 20.6 v the 20In most cases it's due to teflon PCB's and better board components, however there are some re-design issues too depending o... 
transfiguration temper v compliance
If you're trying to figure out whether the effective mass of the tonearm is compatible w/ the cartridge, go to www.cartridgedb.com and use their interactive calculator. You type in your cartridge, your arm, and presto! 
Just bought Martin Logan Vantage speakers.
Remember, the Vantages come "pre-biamped": their woofer is driven by a built-in SS Class D amp. The (external) amp (or 'amp section' of an integrated or receiver unit) that you choose is therefore only driving the electrostatic panel. And for my m... 
Antiskating .... The last analog secret
Yes, I do live in AZ (Tucson) however the temp/humidity may or may not affect the suspension material depending on what it is (hopefully the cartridge designer/maker chose a modern polymer) but temperature will definitely affect the magnitude of t... 
Allaerts down-repair or ??
Dealers of such high-end gear don't just overlook noting serial numbers on invoices -- unless they have a reason. Regardless, you can still hold the dealer responsible, unless he no longer wants to represent JA ;-) 
Allaerts down-repair or ??
TP, as long as you have your receipt, noting the serial no. of the cartridge, there should not be a problem. I'm not sure why JA wants you to send it directly to him. If it's currently covered by a warranty, then I believe the dealer from whom you... 
Antiskating .... The last analog secret
Bob, I know it can be hard to use the visual method with low compliance cartridges. The Dynavector 20X-H (like most MC cartridges) has a dynamic compliance of: 12 x 10-6cm/Dyne. Anything below 15x more or less, is considered low compliance (meanin... 
I got a stylus cleaning kit for, but---------
Mark, it's been years since I read any of the Last literature, but I seem to recall the Stylast was pitched as a product that was compatible with records already treated with Last Record Preservative (I don't remember what their logic was, but pro...
