Cable Snake Oil Antidote
the reason phase coherent speakers aren't the order of the day is because the virtues of that strategem haven't acquitted themselves as highly important. Typically speakers that make that a cheif priority make detrimental compromises in some other...

I've heard it said a mother can recognize the cry of her infantNot sure about humans, but definitely true in many animals.Changing wire is no mystery. Differences can be predicted with math. Audibility, not.Jury is still out on fuses other than ac...

@ostensible_constituency - People spent multiple thousands per mic and thousands more having them rebuilt. Do you think they would do that and use the cheapest possible cable?Some of the best recording studios were built by fanatical audiophiles. ... 
Yesteryears' expensive speakers compared to modern moderately expensive speakers
@almarg +1Cost often has very little to do with performance. FULL STOP.As HiFi is very personal, it's important to know what constitutes good sound to you and you alone... within reason ;-)  AND you are building a system. A loudspeaker than only s... 
Preamp & Subwoofer impedance mismatch?
I use a passive level control of my own design, -10db is about 6.7kΩ in series with the CD player driving a Force sub with 10kΩ nominal impedance in parallel with main amp.I used it with a Parasound A23 which also has 33kΩ input impedance. Current... 
Subwoofer bass issue

Subwoofer Decision
A phase control is also a joke as it is not constant phase across the subwoofer’s range. For example, at 90° setting shift is 80° at 20Hz, 120° at 40Hz and 150° at 80Hz. Best option is BOTH phase control and 0-180 switch.Adjusting XO frequency cha...

Why not $0.50 or $0.60 / ft?Some like 22ga zip @ $0.08 / ft. It's entirely possible their system is incapable of resolving anything better or 22ga zip gives the most musical representation in THAT SYSTEM.Other than snake oil and dishonesty, there ...

My take on this: AudiofoolsnounThose who believe that $3,500 cables let them hear the audio more clearly, when the music was originally created with $25 cables.Many of my contemporaries carried specialized microphones, pre-amps, cables, amps and ... 
Tube amps and heat
OOPS... roof is only about 0.9GW/day for a 12 hr period ~<:-/ 
Tube amps and heat
Tube amps don’t need to be on all the time. 20 minutes is more than enough time to stabilize.Solar input for Arizona is around 8 KWh/m²/day. A 2400ft² roof is about 1.8 GIGAwatts per day.A refrigerator, computer, TV and all the other electric stuf...

A year round solution is to add two small fans to the top of the tube cage.See http://ielogical.com/assets/Audio/PrimaLunaAmpFans.jpg Fans are 60mm x 10mm 12v https://www.amazon.com/gp/product/B00KIDDEP2powered from a DC 3v supply https://www.amaz...

I have a pair of UB5s, as well as a pair of ~1978 Chartwell LS3/5As. I should compare them some time.40 year old caps are probably suspectcrossover to my sub naturally at the point where the mains can't no longer output, and keep the use of the su...

simply starting with a quality power cord, next an Audience power conditioner, next interconnects, finally speaker wires how each step most certainly made a difference-for the good.I've been to similar presentations where they were playing music I...
