QSA : My take on their expensive products

[Piotr_905]

Oh, the SR Blue was definitely too bright for me and too revealing for me. I guess the company has made a significant progress since then.

 

[Piotr_905]

My QSA Violet in price terms compares to the SR Master. I wonder what people think of the differences between these two. What is the "magic" or "house sound" of the QSA fuse at this price level that may have led people to opt for QSA instead of the SR Master for example.

The Master was a latecomer. And SR initially said only to use one in a system, with the rest being the latest below that. I hear it's now up to two at the most. And early QSA user reviews spoke to improvements over the SR color fuses.

 

[Piotr_905]

I may be wrong, but I have an impression it's either SR Master or more expensive QSA? The Violet has not stood the test of time?

Whatever about the latest SR colored version, it's the wrong impression. Check the Master reviews. It's not meant to be used in the same way as the others or QSA, which is probably why it's called what it is.

Good point. So we choose what we like, A QSA for example, and then, perhaps we add one Master, but it's not the question of choosing one over the other.

It's always the user's choice. I can't recall anyone writing about use of both QSA and Master. There's also the Swiss Digital Fuse Box (SDFB) which now is being used in place all of my (QSA) fuses (the box has a WBF thread).

 

[Piotr_905]

I must try those Swiss Digital boxes one day, perhaps. In the meantime, let's stick to the topic of fuses... The simple regular ones.

While I don't want to derail the discussion, the Swiss box is a form of fuse.

 

[Barry2013]

By the way, some people say the QSA fuses have a "house sound", of which get more as you go higher up the line. But I haven't found any details on what this "house sound" is. Perhaps somebody can comment. I have recently installed a SR Master fuse as well, and this one doesn't seem to have a "house sound". It sounds very neutral to me.

I recently installed a dedicated power spur for my system together with a QSA Black/Red wall outlet and in conjunction with my QSA Violet fuses and that combination together with a QSA Orange jitter plug made a substantial improvement to the sound quality of my system

Let's please keep the discussion about the thread topic.

That said, I have a QSA R&B fuse on the PS circuit board for my amplifier. Along with that, I have the SDFB (SRA Takshaka's on both sides) and so far, 3 days in?

I have some great sound. Especially when the rig has been on for over 16 hours. The combination is exhilarating. My work ethic has been unfortunately compromised because of this.

I wonder, what is the deal with the Swiss Digital Fuse Box? Is it really that good? I have an impression this thread is being taken over by its advocates.

Head over to its forum on WBF. I don’t recall anyone comparing the SDFB to the top level QSA fuses, silver & gold, only red-black on down.

Got Orange QSA LAN and IEC... Put them in system - immediate worsening of sound. Waited 24 hours with running signal - no improvement at all...
Deleted them - the good sound came back! What a relief...
I must say - rather expensive experiment

Just about everything in audio takes at least 300 hours of burn in. If you're expecting instant gratification, you're bound to be disappointed in this hobby -- at any price.

Purple is the colour of your nuts that the dealers got you by.

Blue and purple for nuts and red in the face. Next time I meet him I will tell him to reverse direction and fuse off.

Sorry-not my experience... and I built expensive very good sounding system with tons of tweaks. The one exception were Vcaps - about 1000 break in hours and sounded awful at start but it was documented by designer... Black Gates as well.
With QSA most people claimed immediate improvement

Most people?? Never heard that one. You been hanging out at ASR?. But it doesn't matter. If you don't have the patience to allow for possibilities that don't match your experience... I don't know about the guy who runs QSA proper, but QSA-Lanedri, the cable operation, recognizes burn in as a real part of the audiophile experience. Did you buy through Tweek Geek? What does Mike say?

Good point.
I have had a number of QSA fuses in my system for few years together with an Orange jitter plug and yes they do take a significant amount to time to reach their optimum performance
More recently I installed a dedicated power spur together with a Red Black wall outlet so both contributing to a significant increase in sound quality after a run in of now a lot more than 300 hours

I agree with you that something seems off with those observations. I had never seen anyone say that QSA treated products don’t need burn in to sound best. I’m aware of people even mentioning that patience is needed.
