Linear PSU 12v/1.67A, 5V/2A dual voltage?

[Norville]

I need a Linear PSU for my S.M.S.L PL 100
and Matrix Element-i

The specs for both are as follows:

12v/1.67A Element-i

5V/2A PL 100

I've looked on Ali and Audiophonics but its a jungle. Should be dual voltage.

Willing to pay max 150 Euro.

Any ideas?

Why do you need a linear PSU? What's wrong with the original power supplies? Save your money

You are probably right. But Please just answer the question.

I want clean power, linear power. That's it.

Get these filters and use your power supplies.
Most power supplies you can buy complete will have inferior performance, even if you spend well over $150.

I don't think you'll find many people here willing to advise on how to waste money and resources.

Alright then. Never mind my question.

 

[JeremyFife]

No offence intended, and genuinely not something I can help you with if you want to keep looking.

You've had a few responses to your question though now which can make other members notice the thread. Good luck anyway

You're really not doing yourself any favors with some supposedly great and clean power supplies, except wasting money.
In the DIY area, there are some projects for such power supplies that put almost everything up to € 500 (per voltage) in the shade.
There are also enough measurements to prove this.

With a Mean Well PD-45A you're already at 50/120mV ripple&noise. With the filter mentioned, you can easily get under 20/40mV ripple&noise and with a suitable housing you're well within budget. But that's where the air gets very thin for commercial power supplies.

But I would advise you to build the filters for your power supplies first and listen to whether there's a difference for you.
If not, everything else would just be wasted money.

Fair enough. It's a good thought and certainly will consider it. I have been meaning to learn how to solder properly and this might be a good project.

Thing is, I just like the thought of clean power to get a pitch black background.

The background is already probably good enough. But I want to take things to the limit, not having to pay too much.

I have a supra power strip with transient filters and a voltage overload protection already.

The chain is as follows:
Mains-> Supra LoRad cable>Supra power strip>Meanwell AC adapter>Matrix Audio Element-i>Coax cable>S.M.S.L PL 100 CD player(using generic USB power)>Element-i>RCA cable>Musical Fidelity X-Can V8P acting as a tube buffer>Stax SRM-D10 Energizer>Stax L300 with L700 pads.

The linear PSUs I have now bought are going to feed the CD player and Matrix.

Now, even without them. Things sound very high end. I mean, I have some experience in Audio and its really up there.

I don't actually think that the PSUs will do a lot of difference, but I want to explore it and take things as far as I am willing to go with this set up. If nothing happens, at least I like the looks of the PSUs and it hopefully makes the stack look nicer. That's worth at least something.

That's not ultra low noise linear PSU's I see there,just plain linear.
Your 2A demand is somehow limiting for such with your budget.

Have a look around for ultra low noise ones,you may find one that fits:

They certainly look good but none within my budget no.

Have you tried removing the Musical Fidelity X-Can V8P?

It's not actually needed is it? In which case it's an additional component in the signal chain. Even the best electronic component in the world will degrade a signal more than a cable, sometimes not by much and maybe inaudibly, but nevertheless.

I really thought that it elevated everything when using the V8P. Its a recent purchase and it made a significant difference. Of course, people will say it degrades the signal. My experience is the opposite.

In which case it's adding something. Given it has valves in it, probably noise and distortion.

Maybe Keces P3 - a used one sometimes sell for around 250€

Yes, that would be ideal. Sadly no one for sale for a good price.

Yes, it probably does add som 2nd harmonic. But it doesn't impact any noisefloor as far as I can hear.

 

[Norville]

I came to my senses and cancel the orders of the Linear PSUs. I have virtually no noisefloor anyway. Can't see what much else could improve. I am leaning much more on the rational scientific audiophile side of things recently. I support this forum much more than any other.

Congrats on the cancel! If you want to improve your sound, stop looking at the electronics. Your room and speakers are by far a larger factor in sound quality. So start there!

Yeah, I'm mostly a headphone guy.

I have however lots of room treatment in my speaker set up. Big acoustic panels. I also use Fosi monoblocks and a Sabaj D5. Great old Mirage 1295is speakers. Sounds lovely.
