Too Much Power?
northernfox As I tried to outlined in my first post Steve, with these Utopia Be speakers, you need current more that watts, as they are 92db efficient 100watts at 8ohm will do.But with that 2 ohms and 3ohms in the bass you need current, so when i... 
Synergistic Red Fuse ...
nonoiseFuses should not degrade, they should blow when required. Saying that, then a fuse that degrades is crap as well. Yes they will degrade as they operate at or near their threshold,  just like incandescent light globs do, did you not see w... 
Synergistic Red Fuse ...
Georgelofi ... but both Bob and fleschler use SR Black fuses in their systems. Really!!! good luck to them, would have got the same result with just a new 10c fuses.This is what happens to that fine 10mm-20mm wire inside a fuse, from new left, to ... 
Synergistic Red Fuse ...
Pioneer receiver, two cheap floor standing speakers jammed up against the wall between a big screen TV in an almost bare room. Yeppers ... no improvement from the fuses at all. *lol* I can beat that, my stuffs all from Radio Shack or Tandy as i... 
Synergistic Red Fuse ...
I replaced near new SR RED fuses for the SR Blacks and got a real significant further jump in resolution? Shakes head, many times. With all these improvements that fuses have bought, this system must sound better than anyone’s on the whole of Aud... 
Synergistic Red Fuse ...
a top quality fuse. A top quality >$100 fuse may sound better than an aged fuse as stated, but so will a new 10 cent fuse, as switch on surge currents carbonise, stretch and sag the filament and change it’s characteristics over time with an ol... 
Synergistic Red Fuse ...
Frankmlsstl656 posts03-14-2017 3:21amin the spirit of this thread, I thought I should warn people to NOT mark directionality on their fuses. The ink or sticker could confuse the electrons, drawing them off-center. The same is true of handling fus... 
Any comments on DAC going direct to power amplifier or to pre-ampliifer?
Anyway, going directly into my Mcintosh MC205 obviously bypasses the subs and the result was predictable: very clear and transparent but bass thin. Plus I missed impact I get from the lack of subs, which I have time and phase aligned. You do wh... 
Too Much Power?
Your Focal’s have a wicked impedance 3ohms at two power hungry points 80hz and 500hz, and a real bad -phase angle at 60hz which could equate a EPDR of 2ohms. Which is not real good good for a Class-D amp if you like to pump it up a little. I think...

"The fuse element is made of zinc, copper, silver, aluminium, or alloys to provide stable and predictable characteristics. The fuse ideally would carry its rated current indefinitely, and melt quickly on a small excess. The element must not be d...

Is my amp the problem?
almarg  2)The miniDSP 2x4 has a very low input impedance of 6K.  I'm going through the same impedance woes, with yet to arrive a Minidsp 2 x 4 HD to do some bass (<150hz) only experiments with, it's 10kohm input, a little higher than the 2... 
Specific Pre-Amp advice
darkstar1 OPExposure Dual 4 Reg has 24db of gain according to the President. That's a much higher input sensitivity than what your manual states at 1.2v. It's 50% higher.Cheers George   
More discrete R2R Mulibit dacs.
Don’t forget Metrum acoustics they are making there own chips I think maybe you mean discrete circuits, because chips are for the big boy manufacturers to make Analogue Devices, Burr Brown, AKM, ESS ect.Cheers George  
Specific Pre-Amp advice
Exposure Dual 4 Reg has 24db of gain As your amp manual states it only needs 1.2v in for full wattage (clipping) output. Most sources give >2v output, even many phono stages.Cheers George
