$2000 Tektons, which one for my use?
’’OP if you go with Tektons there isn’t anything in them that is expensive.’’ Very true! 
Speaker Recommendation up to 70k
@tony1954,Agreed! 
Tube Amplifier Sound Characteristics
+1 @sbank 
Are Quicksilver power tube amps in the same league as VAC, VTL, BAT, ARC, ...?
Yes!

@holmz, ''So 1 W would make 86 dB.''Just to be clear, only in an 8 Ohm load does 2.83 volts = 1 watt. In a 4 Ohm load 2.83 volts = 2 watts. The OPs speakers are 86 dB SPL (2.83 V/1m) @ 4 ohm.

Also, I do not agree with everyone who claim that speakers with higher sensitivity will sound better at low listening because, at 60dBs sensitivity shouldn't make any difference at all. Agreed! 
A friend told me JBL DD67000 is actually very bad speaker, is it true?
@fiesta75,Lots of info on charge coupled networks. See: link below./www.lansingheritage.org/

@holmz,The woofers in my speakers are the JBL 2234h. See: page 2 section C: internal design and construction last paragraph.http://www.lansingheritage.org/html/jbl/reference/notes/tech1-3a.htm

The 9 volt batteries keep a constant charge on the capacitors in the crossover. Similar to a class A amp where the transistors are always on. (I think this idea came from Ed Meitner.)

’’Maybe you’re right. But there would have to be a reason why the sounded better.’’Because efficiency and sensitivity are not the same. See: tech note below page 1 section C:/www.lansingheritage.org/html/jbl/reference/notes/tech1-3a.htm

@dcevans,Agreed! 
Any Freya Plus owners in Denver?

@celestial__sound ''because 90% of the time I listen at ~60dBs SPL.''At 60dB SPL your speakers are not getting 1 watt or 2 watts or 10 watts, in fact they are not even getting 1/2 watt. At 60dB SPL your speakers are getting milliwatts from the amp...
