home audio however is governed by csa regulations
and are required to have the only rms ratings of the product either on the unit/box/manual.
the fuse on the unit is for protection of a short in the unit itself.
110v and 12v are two different aspects however wiring the spkrs with better quality wire i found makes a difference especially if your spkrs are across the room and you have 30' of length!!
if you see some of the new gear coming out in the next little while head units primarily alpine
instead of having 50wx4 on the box it says 17wx4
regulations are coming
no more wool over the eyes for the average consumer!!!!

I had him return it and picked up an RCA brand one from RadioShack for $20.
I know some of you audiophiles might think that the Monster brand cable would be a lot better but my dad's already got hearing aides. I doubt he'd notice a difference between ANY audio cable

* The above is not meant to depict that all FS associates are incompetent. Many shops have incompetent sales people. </font>[/QUOTE]There is definatly a differance Mike.. A cheap Optical cable with have a poor connection point at both ends. while a superior cable with have a better build quality minimizing loss at the connection point... 99% of any loss in an optical cable in the home audio environment will be in the poor connection.. which is why digital coax is always a better choice.. But optical sound cool and it impresses customers...(wooooo optical).
So ya there is a differance. [img]tongue.gif[/img]

^^^^ oh my son, it sounds like you drink the Kool Aid.... I have not experiance any difference in blind A/B tests between a "cheap" optical cable and an expensive one. The issue of "connection point" is not an issue -- it either lets the light pulses go through or it does not.
Yes, a "good" Coax digital cable will sound better that an optical cable IF:
A) it has true 75 ohm connectors
B) it is well shielded
The one primary advantage of opitcal is that it is "idiot proof" and that there are not any bad optical cables.
PS...oh and by the way... any good video cable is a good "digital" cable, since they both have to be 75 ohm.
DON'T DRINK THE KOOL AID!!!

since all home amp power supplys i've seen consist of a transformer and capacitors and rectifiers

Looked around, most stuff I see is rated to Federal Trade Commision standard... Continuous RMS power all channels driven into some load/bandwidth/%THD (they have to say what)
Also found some IEA ratings...
CSA & CEA ratings seem to be for powersupplies (DC & AC, respectivly) [img]graemlins/dunno.gif[/img]
I'll be back at my buddies sometime soon, I'll take a closer look at his kenwood reciever I mentioned... but based on it's size and output of the speakers he was running.... didn't seem like it was 100RMSx5 at all.....
Guess I could be wrong thou...

CSA marks are a sign of confidence for millions of people worldwide, every day. Here's why:
CSA marks mean a product has been tested and meets applicable standards for safety and/or performance, including the applicable standards written or administered by the American National Standards Institute (ANSI), Underwriters Laboratories (UL), Canadian Standards Association (CSA), National Sanitation Foundation International (NSF), and others.
CSA International is a North American leader in product testing and certification, with a respected history dating back to 1919.
CSA works closely with the International Association of Electrical Inspectors (IAEI), the Electrical Safety Foundation International (ESFI), Health Canada, provincial regulators, and the U.S. Consumer Product Safety Commission (CPSC) to promote standards for consumer safety in North America and around the world.
· CSA testing is accepted by key conformity assessment organizations in the U.S. including IAPMO and ASSE
CSA field representatives conduct more than 50,000 factory visits each year, worldwide, to ensure that CSA-certified products continue to meet the applicable standards.
