Are interconnect cables worth $15,000?
Everything is worth only what you are willing to pay. 
concrete slab vs/ wood floor - pros and cons
Removing the concrete floor may cause you problems. Sounds like what you descibe is a floating slab construction where the entire weight of the garage is spead out over the 11 by 17 area. If you remove the slab what remains is the concrete under t... 
Why do amps sound different?
Cost. Every amplifier is designed to a price point. Since there's no such thing as a perfect amplifier, each manufacturer strives for the best sound within a budget (assuming that's the design criteria). Everything inside the amplifier imparts dis... 
What's causing distortion at musical climax?
You left speakers off the list - they may not be able to handle the power or the drivers have reached their excursion limits.You also do not make it clear if it's limited to vinyl only. 
Balanced SET Amplifier
The XLR inputs of the Lamms are for convenience - to save an owner the expense of new IC's - and not for balanced operation. By definition, single-ended-triode (SET) operation involves amplifying the entire signal with only one output device. A ba... 
Second failure of new amplifier
Is it always the same tube socket? If it is, check the socket under a bright light. Look for burn marks, carbon deposits or mechanical damage in the pin holders and solder points. Use a magnifying glass as even a carbon coating could cause an arc ... 
Are attenuators linear or logarithmic?
Attenuators are logarithmic because our hearing response to changes is SPL is logarithmic. Each step resistance is calculated to result in the voltage ratios being doubled for every 6 dB's. Even though each discrete step is linear, the combined st... 
FUSES VALUES: 250 volts VS 500 volts
Use an 8 amp fuse, no more no less. If you were to use instead 4 amps you would be popping a 30 dollar fuse every time you try to power up.Never ever listen to anyone contradicting the equipment manual or the manufacturer's tech support. 
Damping factor or watts?
DF will not control the driver excursion. The driver will move somewhat with inertia when the signal stops regardless of DF. What happens is that the moving driver acts like a microphone as the cone moves in the voice coil creating an emf. If the ... 
The Most Realistic Speaker Technology?
The reason that it's confusing is that if the speaker technology you're looking for existed, it would dominate the market and the choice would be staring at you in the face. All speaker technologies are a trade off with each one being more "realis... 
Amp Designs That Are Able To Drive 4/2 Ohms Load
It's a little more involved than just the power supply being unable to provide the current to double the power as load is halved. You can design two amplifiers with the same power rating at 8 ohms and have one being able to double power at 4 ohms ... 
difference between 8ohms and 4ohms and voltage con
If you don't know the power consumption of the amplifier then the output power should be a third or less of the converter wattage rating. In your case, 320 watt ouptut should have a converter rated at least 1000 watts. Ideally, any power product s... 
For people with experience with Class-A amps
It could simply be due to a different thermal resistance between the sinks and the transistor casings. If the thickness of the mica insulators vary slightly, it could throw off the final temperatures due to a different rate of heat transfer.Could ... 
Why are choke power supplies still not common?
Cost - the unit price of the inductor and costs involved with vibration isolation, the space they need and the added weight. Chokes went out of favor with the availability of electrolytic caps as they became cheaper and more reliable. 
tube Watts vs solid state Watts
The limiting factor IS wattage. Tube amps have a high output impedance and low current which means their power is limited to the output tube plate dissipation. A transformer's needed to reflect the low speaker impedance and this limits the amplifi...
