How important is the pre-amp?
As far as “standards” go; it would seem to me that if amplifier manufacturers would adapt a standard for single ended input sensitivity of say between 2 V (CD) and 2.2 V (HDCD) and a balanced input of between 4 V and 4.4 V for full power output, i... 
How many watts??
 If I may add to ^ @liquidsound 's post.  Other considerations include room gain, which most will appreciate as an apparent increase in volume for a given power output. And that many loudspeaker's sensitivity is rated as 2.83V/1M rather than 1W/1M... 
Solid state amp to go with tube preamp; used ok; budget: $3k max

Collective letter s to Stereophile
A follow up; while I don’t remember or doubt the validity of @grooves negative review, for a while there, Stereophile came to look like a Musical Fidelity catalog.  FWIW, I never found any of their gear appealing. 
Class A into Class AB
@pjcoughter, I believe the meters were intended to entertain not mislead. I would hazard a guess that if asked, Nelson Pass would readily admit as much. 
Class A into Class AB
The meters on home audio gear are almost never calibrated and more often than not mislead rather than inform. 
Are Pre-Amps necessary?
Some DACs with volume controls have balanced outputs. 
Are Pre-Amps necessary?
^ This will only inform you as to how it works in your system(s).  Not necessarily as a general rule. Ideally you’ll have a DAC with extra available bits for volume attenuation, with a voltage output that matches the input sensitivity of your ampl... 
Are Pre-Amps necessary?
This has been covered here on Audiogon many times before, again; it depends on the system. 
Class A into Class AB
Re: the Threshold 500’s.  Claimed 20 output devices per channel, for 250 Watts per channel into 8 Ohms with about 20% of that being Class A,  the Class AB power output could steadily double down into 4 Ohms, but while doing so the Class A output w... 
Seeking recommendations about material, design, makers of low-lying rack for gear
Make sure you have enough depth, yet short the shelves in relationship to the support posts, which will help relieve connector stress and look a lot better, and scalloping those rear shelves will will assist in cable management. Make shelves a min... 
Need a new FM Receiver that works very well
I don’t think manufacturers are investigating much into their FM tuners anymore. The ones commonly offered might just be there to fill out the line.One can get a top quality vintage piece and have it refreshed for that kind of money.

Location, location, location. Depending on where you are receiving your desired signals will determine what matters most, such as sensitivity or selectivity. Understanding Updated FM Tuner Specs, March 1973 Popular Electronics - RF Cafe  
How many watts??
Many amp designers say amps tend to work at their most linearity at around 20% of their full rated output. As has previously been posted, volume increases require logarithmic power output. Having an additional 80% of total power output for headroo... 
Matching solid state amps with tube based pre amps
As has been previously mentioned, when combining the two, one has to be mindful of  the impedance output and input impedances. How ever, the volume issue mentioned is more likely to be a result of  a high output voltage (typical with tubes) into a...
