Subwoofers are a superlative room treatment
I ask because I’ve been debating the expense and complexity of adding subs to my Sound Lab ESLs. As I’m sure you know, it’s technically easier on the main amplifier if you high pass. But it’s simpler and less potentially harmful to phase response ... 
Subwoofers are a superlative room treatment
This is the Analog Forum which usually means vinyl but we all listen in the analog domain. Please clarify, are the S7s attenuated by a high pass filter at or near 70 Hz?  
Phono preamp or SUT for low output moving coil
Virudian, but how about a situation where the internal R of the cartridge is well below the input Z of the phono stage? These days that’s quite possible. Is that now voltage drive, or what? There are now several LOMCs with R less that 2 ohms and s... 
Phono preamp or SUT for low output moving coil
Viridian, As i see it, and as I just wrote it, yes, in theory the current driven phono stage presents a dead short to the cartridge, but in fact it cannot, because if it did, you would have a fancy mute switch. There's the rub with current drive.  
Phono preamp or SUT for low output moving coil
It's very difficult to set a firm upper limit for the internal impedance of an LOMC cartridge that you want to work "well" with a current driven phono stage. This is because each brand of current driven phono stage will present a different input i... 
Audio Note M6 phono tube suggestions
For those who like to “roll” tubes, the tube type is paramount. So you’ll get better or more useful information if you say what tubes are required in your AN phono. As for me, I think it’s a bunch of hooey, because tubes don’t stay the same over t... 
What devices have you found useful when inspecting your stylii for cleanliness?
If your SQ is only CD-like, you have a way to go. Hi Rez streaming is a legit alternative to vinyl, but, IMO, high quality vinyl has it all over RBCD.

De nada.

At least RB got what he expressly said he didn’t want, recommendations for how to clean not only styli but LPs too.   
What devices have you found useful when inspecting your stylii for cleanliness?
RB wrote, "my current tone arm is a fixed head-shell design so I cannot easily get a good viewing angle - the arm does not tilt much."  Do you really think one can inspect the rear of the stylus and the cantilever (which also can accumulate dirt a...

And obviously a magnifier of some sort. Shop glasses with built in magnifying lenses work. But more mag power is better. Anyway you can’t possibly get a good look without dismounting the cartridge if tonearm has fixed headshell.  
Tonearm paralysis by analysis
Raul’s advice is the best you’ve received.  
How To Control The Eager Beaver
Larry, That is an interesting idea, but I don't get it. The force applied to the stylus/cantilever would be to counter the force of friction between stylus and groove, and here, with a tangential arm, we have a cantilever that is always tangent to... 
How To Control The Eager Beaver
No, you are correct, RB, there should be no skating force with a tangential tracker.  The only side force would be to overcome any friction in the carriage, and there is always some of that, which is why the best LT tonearms in my opinion float th... 
Tonearm paralysis by analysis
Then you just want a new tonearm with a high effective mass.  You've listed a few, except that with the Moerch, you need to specify one of the heavy arm wands, and with the Reed, you want the cocobolo or panzerholz arm wands. The other Reed wood o...
