Mmm.. I would have gone for the preamp first as it's earlier in the chain . TBH it only takes a couple of minutes to swap the fuses around anyway . You would also be surprised at how a DAC will improve with a better power supply . My Denon DAC improved markedly when I substituted the wallwart with a quality linear PSU , so I would try it there too ( unless you like to use the properly rated fuse for each piece of equipment ) .

Brian

A fragment of packing polystyrene had worked its way behind the power meter glass, so I took her top off to get it out ...

Oh my god! There's nothing wrong with the bidet is there?
“Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".
“You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”
"You don't have free will. You have the appearance of free will.”
“There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”

Cool. My uncle just gave me a Beogram, but I have no idea how to work on linear trackers. I have to do some reading.Originally Posted by jandl100

Told Ya!Yes , if we're being pedantic , it does what it's supposed to doHowever , like you I think , as far as SQ goes , it's excellent .
I've just this minute plugged a Linear PSU into my superhub and initial impressions are very good indeed

Told Ya!Yes I agree about changing the internal fuses , you have too many boxes to do this anyway
My first port of call would be the plug feeding my mains block . Are your amps plugged into the mains block too ?
Where are you fitting the next SR Black mate ?
EDIT : This linear PSU into the Virginmedia superhub has yielded a very nice improvement in SQ BTW . Looks like it will be staying put

Have two SR Blacks in my lash up so far:
* Internally in digital Source (Logitech Transporter)
* IEC Fuse in my Densen Pre
Bigger jump with the Pre, and my original WT(actual)F! post was about the improvement I got with the Transporter.
...next up the IEC fuse for my Dac's linear PSU.
In 30'odd years of hifi hobby-ism, I've never blown a fuse yet.

My 2nd SR Black fuse arrived today.
Where to put it?
Tried pre-amp --- mmm, no definite sq improvement. Real disappointment.
Moved it to the power amp --- ah, yes, better focus, more transparency.
Hmm, curious. Maybe they don't benefit low current draw devices?
But the 2nd fuse is a keeper, too, for the power amp.
Might try it in the DAC.
