This "When neighbors in houses next door complain about the earthquake shockwave?"
I was walking with my family one evening around the neighborhood and I heard this low-frequency rumble from the sub(s) across the street and almost a block away! I live in an upscale neighborhood with large...
You need a professional acoustician to provide the answer to your question.
I could tell you this much, your speaker in the right room with the correct bass treatments will have a tremendous kick. Guaranteed 100%. The restaurant/coffee shop is probably way larger space than your space which...
Hi JimA84,
Take a look at my post #96 and you will see that the KEF KF92 subwoofer goes down flat to 15Hz and it's not sitting on the floor but on the isolation platform. My floor is the engineering wood glued to the concrete foundation. I'm not sure how accurate the umik-2 microphone is but I...
I will make an assumption, that there is no dedicated headphone amp in these AVRs.
The output you will hear on the headphones will be coming from the output transistors (minus the resistors and another electronic component in the headphone circuit).
All you doing is trying to swap your...
Plug the headphones and without any input connected, turn the volume up.
How bad is this hiss/noise?
After that, do the same test with the older AVR and compare.
If the nose of A1H is way louder, I would assume something inside got loose during the shipping.
"when it is on, I can hear the 2 front speakers + center hissing if I put my ear within 12 inches from the tweeter. The hiss seems constant level with volume set from 0-80 or so."
If this is coming from the AVR transistors (which I assume it does), then hiss should get louder as you turn the...
Gene at Audioholics just tested the Arcam Radia A25 integrated amplifier and he was impressed.
He measured 100dB SINAD below 80 Watts. He also pointed out that switching from low to high rail is pretty much under control.
No...
I would love to see Amir review this amp (PA240) for two reasons.
1) The high gain setting is the same as the Denon internal amplifiers or very close to it.
2) The power supply has an option to work on 120~220V.
