The 88s will have better bass control than the V4s. 
Slam possible with Tubes instead of SS ??
Tube amps with slam include the higher powered ARC and VTL amps, even with cone speakers. My own Quickslver M-135s definitely do the "slam thing". 
Adjust+ Vs. Fozgometer For Azimuth Adjustment
Great info. Thanks. 
Is it okay to talk around your speakers?
A wink is as good as a nod to a blind horse. 
Sealed vs Ported Subwoofers
You should definitely not sell a speaker because it is or is not ported. Neither design approach is inherently better; it depends entirely on the implementation. Wilson speakers are ported and Magico prefers sealed enclosures--both produce excelle... 
Audio Research SP10 vs ?
I own an SP-10, SP-11 and the new Quicksilver Full Preamp. The latter is what stays in my system and, at $3900 including an excellent phono stage, it is a bargain in today's market. 
Does the Audio Research PH-3 Invert Polarity?
Looking at the schematic, there is a FET gain stage followed by a cascoded tube gain stage, followed by a cathode follower output. Ergo, two gain stages means it does not invert phase. 
ARC LS25 mkII adjustment
There are no voltage readings on the ARC schematic, but you could check the voltage drop across the 1 K source resistor; it should be approximately equal. Unless you know someone fooled with it, I would not worry. 
ARC LS25 mkII adjustment
The trimmers you see are for the constant current source in the FET voltage gain stage. Do NOT adjust these when you switch tubes. Did you know that all the gain in that model is provided by the solid state FETs? The tubes are used as cathode foll... 
Rawson Amps
I know nothing about the quality or performance of the Rawson product. I do agree that it is inappropriate, and probably illegal, to sell Pass's designs commercially. 
Quicksilver Line Stage with ARC amps?
The Quicksilver linestages (there are 2 versions; one employs 12AX7s and the other uses 6DJ8s) work fine with ARC equipment. Yes, they both invert the signal, so you will need to reverse the amp-end or speaker-end of your speaker cables--unless yo... 
Mods to Altec 1569a amps by ?

Quicksilver V4 or Silver 88 advice needed.....
If you can get by on the 80 watts of the Silver 88, it will control cone woofers better. It has the lowest output impedance and the highest damping factor of any Quicksilver amp (or compared to the vast majority of tube amps period). It can drive ... 
SOTA Cosmos or Garrard 301 ?
Just a prediciton, but if 20 people respond, 5 will say the SOTA, 5 will say the 301 and the other 10 will say whatever turntable they own. 
What did you own in the 60's?
Fisher 202 receiver, Dynaco A-25 speakers and Dual 1215 turntable with a Shure M-91ED cartridge. I thought I was in Heaven!
