any thoughts/experience with the RELATIVE merits of upgrading fuses that lie in the powersupply path vs in the signal path, itself? forgive me for applying "logic", as I know to trust ones ears, but it would make more sense that a fuse in the signal path would have more affect than a fuse on the incoming AC, acknowledging that AC powercords do, indeed, matter.....just interested in others experience thanks J
What’s your deal? Who are you? I keep seeing YOU and a couple others attack without provocation. Normally completely off topic and no contribution to the thread, just an attack on a person.
I usually praise people in public and chew in private.
How does MCs suppository habit’s remotely concern you. You are a strange one.. If you like the guy I can probably introduce you.. BUT the suppository thing.. Take that up with him..
Look out MC he’s got a blow up doll with YOUR name on it.. No more posing in the group photos without long pants.. the BOYS are getting a little to happy, "let’s say"..
I've owned a few pass designs and I've yet to find a power supply issue.. I just haven't heard the results from fuse swaps in his stuff. Mac is another one. I've owned a few and couldn't tell the difference.
To tell the truth if a fuse in the AC path changed anything I normally bypassed the fuse with a silver or copper jumper.
After the power supply because I'm a valve guy I take pretty good care not to mess with the protection circuit IF they have it.. My Cary sure liked fancy fuses in that part of the amp.. Another month it will be back in service.. Still to hot here.. 100 degrees yesterday..
The bass system I use 12k Behringers and DCX2496 active XOs. What a great inexpensive powerful system. I'm really liking "circuit breakers" and HEAVY copper PC.. :-) BOOM, BOOM!!
OP In your Pass is there a fuse on the other side of the power supply?
Pass is one of those amps. It has such a great power supply, not a lot of room for improvement. Krell and Ampzila, Threshold, huge PS and TO ME the AC fuse and the PC other than being big enough, didn't make that big of a difference.. Ampzila the PC was cold welded in..
The + side of the rail for sure. Threshold had 2 fuses one on both + rails of the amp. I used gold plated Acme back then.. There was no SR that I knew of..
A lot of speakers had inline fuses too. I bypassed all the mid driver fuses in Infinity and Acme fuses for the highs.. 1990s. I still have one set of Infinities set up that way.. RSIIbs.
Fuses count especially in the sound path or after the Power supply..
My Mac preamps have a few inside the MX series. Inside yes, the AC fuse no.. Cary is the same way.. The PC on the Cary makes a huge difference but the AC fuse didn't.. After the PS it sure did though. That is a weird one.. ALL SR fuses though..
your responses and interest is appreciated, thank you.....AGAIN, I was looking for not theoretical but subjective observations as to which fuses seem to make greater/lesser change in sound.....
I have a Valve unit that has fuses in three places. Two made a difference one did not the Power cord made a difference way more than the AC fuse I couldn't tell the difference.
The other two were in the valve protection and transformer circuits, that was quite the sonic nugget indeed. I have a pair of 71.00 fuses coming we'll see if they better the SRs..
BTW, not to often I recommend a fuse, but there are places a piece of good copper or silver goes a long ways.. The problem is burning down the house if something gets sideways..
House breakers have held up so far.. I sure had a mess after a cable drop two years ago.. First and hopefully last.. Not a single fuse inside an amp blew, a 20 amp breaker DID.. 3 right channels failures over the next couple of months. ONE cable drop..
