Moving away from inefficient/low impedance speaker in order to move to a Tube Amp
Why bog things down with a low impedance speaker? In a bedroom system it won't matter so much.  
Tube Vs. SS Preamps
i am curious to know what you believe to be the source/reason/technical underpinning behind top level tube gear being able to generally (exceptions exist of course) provide a greater sense of air and vast imaging (size, depth in particular) - com...

I don’t know whether the SS SG phono stages account for this but I’d be surprised if they don’t incorporate some corrective filtering in the 500 to 2000Hz region. @lewm The last time I heard one, it had no eq. The claim was that it didn't need ... 
Finally Learned: Subs serve much larger role than adding more low bass
I'm told the Room Perfect in the Lyngdorf makes setting up 4 subs much easier, but I've heard that crap before... time will tell. I'm sure it would. You can't fix a standing wave cancellation using room correction. The correction will tell the ... 
Moving away from inefficient/low impedance speaker in order to move to a Tube Amp
Thanks...the system will be a second floor bedroom, that is around 19 X 15, with standard 8 ft ceilings. In a bedroom system your speakers will be fine if you have the space unless you really plan to blast. I would think an amp with 15-20 watts... 
Tube Vs. SS Preamps
What is "fatigue free" ? @vinowino Its a lack of audible higher ordered harmonics (which, if audible, are perceived by the ear as harshness and brightness) and also low intermodulation distortion; intermodulations also contribute to harshness a... 
Tonearm for Technics SP-15
OTHER ARMS with VTA on the FLY that fit on the SP15? Triplanar would be an obvious choice and would suit the SP-15 nicely. They originated the adjustable-on-the-fly VTA tower design used by VPI, Durand and others. Triplanar

RIAA EQ is +20dB at the bottom, -20dB at the top. SG does not require this so the statement is true.  @millercarbon  Not really... The problem is that by the time you get to 20KHz you're not going to be 20dB down. Please look at the actual RIA... 
Dustcover Blues
Because of the way this works it requires no RIAA equalization. One of its many advantages over the conventional approach. @mijostyn @millercarbon This statement is false. While it is true that the cartridge has an output that seems to compleme... 
Finally Learned: Subs serve much larger role than adding more low bass
Or it the Swarm only effective scattered around the room? @mglik If your mains make bass, I'd place the Swarms to the side or rear of the room. They are only a foot square and if the driver is facing the wall (and the sub is only 2 inches or so... 
Moving away from inefficient/low impedance speaker in order to move to a Tube Amp
@fjn04 How big is the room in which this speaker is being used? If you are planning a lower powered tube amp and need to fill a larger space, the Harbeths won’t do the job. They are 6 Ohms, and Sensitivity is rated 86dB, meaning their Efficiency ... 
Amp hum.
Touching the amp or pre amp changes the volume of the hum. That isn't a tube. That's some sort of ground problem; apparently its affected by heat. Does it do it on all inputs to the preamp? Since its in the right channel only, power cords and... 
TL074 vs.TL084?
@kakwu Generally speaking the older the opamp design, the less gain you can get out of it before it starts to have a 'sound'. Even with modern opamps the Gain Bandwidth Product they have makes it dicey asking for more than 20dB. With these older d...

Finally Learned: Subs serve much larger role than adding more low bass My GF commented on how the addition of the subs really helped out the tonal balance in the high end- how the system became more relaxed.  
ProAc Response 2: CJ CAV45, Cary SEI 300B, or Cary Rocket 88?
@leahy back in the early 90s when that speaker was made we sold a lot of our M-60 amplifiers for use on them- it was the most popular speaker used with that amp at the time. That amp made/makes 60 watts. Unless you are really serious about low lev...
