Crossovers? How do you evaluate if crossover is any good?
Speaker designers choose crossovers not on which is best but which is best suited for the job.  
New DAC issues
The Gugnir is designed by one of the best digital engineers in the business whose company does not have a dealer and distribution network to take half of the sales price, so a price based comparison is not a good metric. Sure, there could be somet... 
Vacuum Tube preamp with my KRELL KAV 250a, a no no......WHY?
Krell does not use coupling caps at the input which can result in problems if DC is leaked in from the preamp (both for the amp and speakers). The upside is better transient response as the signal is not impeded a constant charging and discharging... 
A switch for 3 amps
Go with the Luxman AS-55. It uses heavy duty switching contacts which never get "dated". Most switches are rated for DC voltages, which is why a flimsy looking switch can be rated for (DC) 10 amps -- but pass a 10-amp AC voltage and it arcs the co... 
Dedicated mains supply unexpected result
From what you're describing the amplifier is not working correctly  after the mains cable was replaced from the meter to the panel. Call the electrician back and explain the amplifier is not working correctly and can he please check over his work.... 
New expensive power cord for amp and no change in sound?
The price tag does not always reflect performance. If this is a major brand cord then more than half of the selling price can be dealer and distributor markup and the rest of the cord could be sourced from major manufacturers such as Belkin or Eat... 
A stupid question(s) about power cords
1. It is to orient the plug correctly so the hot and neutral of the receptacle matches the hot and neutral of the equipment.   2. Not necessarily. The dummy ground pin almost never has a wire welded to it so it does not connect in any way to the... 
To upgrade a separate power supply?
Depends on the voltage rating of the caps, what voltage is applied to the caps, and the ambient air temperature surrounding the caps.  
Limiting a full range driver
This is one of those it-may-or-may-not things. Even if you crossover the drivers at 100hz, they are still 8-inch drivers. The midrange performance should not change since the relationship between the radiating area and wavelength (frequency) is st... 
is anyone using an Aurender streamer with Schiit Yggdrasil?
I have it also, the Yggy DAC with the N100H. Excellent sound; you'd be hard pressed to get better at any price. However, when I first got the units about seven years ago, I had problems with uncompressed .wav and .aiff files larger than 400MB not... 
How does a preamp die from sitting unused for a few months?
By checking the fuse did you do a visual inspection or did you do a continuity test with a multi-meter? A fuse may look fine but can be broken inside. If you don’t have a DMM replace the fuse and try again. If that doesn’t work then maybe the pow... 
Mysterious power tube behavior
If the bias reading follows the tube then it's not the bias circuit -- the tube is bad. The fixed bias bias circuit uses a 10 ohm resistor at each cathode and the voltage is measured between cathode and ground (the voltage is converted to milliamp... 
2a3 Tubes - Favorites?
RCA Cunningham single plate. Nothing comes close.  
Measurements for a dedicated line
The neutral should have no more than 2 volts to ground. If you have more than that (as measured at the receptacle) the first thing to do is to go to all the outlets with a plug in receptacle tester and make sure they all read ’wired correctly’ and... 
How does bi-wiring work?
It doesn’t work any different than non bi-wired. From an electrical engineering standpoint, the amplifier terminal and the two speaker terminals are the exact same node. The only advantage IMO of bi-wiring is that the sonic signature of a speaker ...
