Eldartford, its my opinion that in high end audio you build the equipment to do the job, then figure out how much it costs when you are done. It is a bit different from targeting a bomb :) 
What year did tube lose to SS
In 1986 Pioneer and Sansui were both still making a tube receiver (all tube except for the phono section). By 1969 both had stopped. So my vote is 1968 was the last year that the major audio companies were seriously into tubes.Mac got out in 1969....

Eldartford, that one is easy! We use a linear recording method, even if recording digitally. By that I mean linear as opposed to logarithmic.The linear system requires flat frequency response. So we adhere to getting the RIAA correct in the same w... 
Why is the price of new tonearms so high
Perrew, one could use the tape outs of our preamp, but one function of the linestage that most people don't realize is that it must control the interconnect cable as well. In a stand-alone phono section this does become a source of coloration. Tha...

Eldartford, it might be, but in the world of high end, the difference between HIFI and the ability to sound like real music exists in the nuances. That is why there are Teflon caps, high precision resistors, care in grounding layouts, spec-ing out... 
Sensitive enough speakers for low power SET
Classic Audio Loudspeakers would be another. They make a Hartsfield reproduction that is about 103db and very wide bandwidth, plus the T-1 and T-3 models (which are available in field coil versions) are about 97 db (98 if field coil) but have band... 
Why is the price of new tonearms so high
Perrew, as T_bone has pointed out, we do make exactly that, continuously for the last 20 years.Its not every day that someone asks about something like that, so I had to ask. Fortunately, operating a cartridge in balanced mode is at least one thin...

Eldartford, you are right about that process, but the producer of an LP would never have the EQ of the RIAA messed with! Usually the issue is a private studio and producer have made a recording. They want an LP, so they send the tape to someone wh...

Perrew, are you thinking of an all-tube fully-differential phono stage too?

Dertonarm, I was thinking the same thing, but apparently neither of us could follow her advice. 
SET amp w/Neg feedback?
Rleff, the key to that is a flat impedance curve. The Avalon Eidelon does that well, as well as most magnetic planars, whose impedance curve has nothing to do with box resonance :)There is another issue- the difference in performance between low i... 
Why is the price of new tonearms so high
In its day the FR arms were OK, but they have long been surpassed in terms of State of the Art. These days the better arms will be seen to have their bearings in the same plane as the LP, which helps the arm maintain steady tracking forces when pl...

Eldartford, the unit that I use has bandwidth out to just shy of 30K. The electronics have a bit more than that, but not much (they were designed in the late 60s). I don't think you could say that there is a 'typical' cutter, as they are all desig... 
Blown woofer from a bad tube? Is this possible?
Short answer: no.The speaker is damaged for other reasons. 
SET amp w/Neg feedback?
Rockadanny, it all has to do with the intention of the designer. In general, if the designer uses tubes its probably a Power Paradigm speaker he created. Voltage Paradigm designers usually use transistors. That will answer the question about 95% o...
