Does anyone care to ask an amplifier designer a technical question? My door is open.
So my question is, why is it tubes are able to do that? Is it a matter of tubes being lowest in distortion at lower-signal levels (where imaging resides?), and transistors in their curves highest?Back in the 90's when emulating gear in digital, we...

I’d like some flexibility with whatever I choose as a source switch/level control in case I decide to use a different power amp. See http://ielogical.com/assets/Audio/PassiveLC1.png here http://ielogical.com/Audio/#LastHurrah. It is possible to us...

Passives should be at least 10kohm to suit "most" situationsIt depends on the source output impedance what the passive resistance should be. If the output impedance is < 500Ω, a 5k pot is fine.Pots have a different sound than stepped resistor c...

for anyone that doesn't know that Mr Kait, see his Brilliant Pebbles http://www.machinadynamica.com/machina31.htmon his Machina Dynamica site.Rumor has it his system is a battery powered Walkman CD player and headphones which obviously gives him e... 
A problem with AC Power you may not have considered.
If I use the wall receptacle next to it I get a lot hum for reasons I have yet to determine.Likely different circuit and a ground loop.Stick with plain, old school incandescent bulbsHaven't a problem with a dimmer since the '70s. I use two LED tor...

@ivan_nosnibor All is on and within the home’s circuit.The panel is a direct short to the transformer. To have an oscillation period of days [0.0000115Hz] to settle over weeks would require ENORMOUS C. The 0000 cable running to my transformer has ...

minimize artifacts occurring from the interconnect cable between the preamp and amp.A second reason is that a preamp can provide a fairly high impedance load for the sourceSource output 22R, amp inputs 23k5 or 100K. Adding a preamp with attendant...

Cables can be overcooked There are many MEASUREABLE phenomena which account for system changes. Why ignore them and ascribe to cooking?

@bdp24 - dual controls are not too fiddly if they are 1db or less stepped@apogee14151617 - all components active and passive alter the sound. There is no electrical reason to have a preamp if the source has output level control or the amp has inpu...

@ivan_nosnibor - laughable. The wiring in your home goes back to the power company transformer which has an extremely low impedance. If it did not, any perturbation on a neighbors line would manifest itself in your home. Only when a transformer is...

There is a potential issue with “auditioning” cables or anything before the burn in period is complete, assuming that the cable is ever completely burned in. That issue is that the burn in process can sometimes be a non linear one, with up and dow...

The earth ground is for lightning. It carries no current. The ground must return to neutral in split 120v systems or the system MAY BE LETHAL.PLEASE see https://centralindianaaes.files.wordpress.com/2012/09/indy-aes-2012-seminar-w-notes-v1-0.pdf b...

@barnetk - two pieces of copperCables are far more than two pieces of copper. They are also plastic, cotton, geometry, connector and join method. Cables can be designed or engineered. Most audiophile cables are designed and their defects sold as b...
