New/upgraded TC-7520 power supply?

[Covenant]

Your last sentence implies that linear is better, obviously you have a different perspective on it. I guess because I noticed a considerable difference changing to a linear supply for my squeezebox I anticipated that a linear may be better for the 7520.
I wasnt having a go-just want to know which is best.

What did you do for the Squeezebox psu ?

Hi Peter,
I had it made for me. Basically its a wooden box about 150x150mmm with switch on the back and 64000 uf capacitors inside. Cost £100.
Very pleased as it seemed to open up the soundstage.

In order to drown out the sound of engineers - installing central heating - next door, I opened up the volume a lot more than usual this morning.

'Sinatra at the Sands' followed by some Eurythmics and some George Thoroughgood & the Destroyers and the Shamen and Blur.

A mixture of mostly lossless iTunes files and a couple of 256kbps AAC from the laptop (USB).

After that I slipped on Roy Orbison's Black & White Night DVD (DVD/HDD recorder is connected via digital optical audio output to the TC-7520) and gave that a blast.

The slightly higher volumes used today helped to confirm that this unit is performing extremely well!

Please bear in mind that I have only had the LM4562NA opamps upgraded for about a week, so some of this improvement is - no doubt - due to them as well. Also bear in mind the TM3 connections fig-8 shielded mains lead which is not standard with Stanley's new power supply.

Compared to before I first bought the TC-7520, it now sounds like someone has dropped a 50 watt Sugden pure class A amp into the system without my knowledge!

chebby,

Have you formed an opinion on the difference, if any, between the old style plug-top PSU and the newer PSU when used with the TC-7520?

As Mr.B has said "The TC-7520 draws its supply from the internal PSU, not the external one. The external PSU is used to charge up the internal PSU and keep it topped up." I wonder if there's much mileage to be gained from changing from the old style plug-top PSU.

Any update as to availability?

Have a look at this:

A possible alternative?

I strongly advise people to avoid that POS power supply.

My first PSU failed 3 months after the warranty expired. The second PSU failed after just 3 months. My third PSU now sits in a drawer gathering dust.

If you want a second opinion read this,

Thanks Getgaff,
Glad I asked on this forum before buying it. Craptastic is the word.
Stan has gone quiet about the new supply, any other suggestions?

I use the Maplin one long recommended for the 7510

I use it wilth an after market power lead ( as thick as yer wrist!) and I find it a good improvement over the standard.
The noise floor seems lower, less mush in the background.
Dynamics are better too.

It can be set to 12v or 13.5v, some recommend one setting, some the other.
Suck it n see.

I run it at 12V as 13.5v acts like a "loudness" button in my system, artificially boosting the dynamics and generally being a less subtle sound.

I'd go with this one if your looking for a PSU - it makes a good difference.

Cant comment on Stans new one - it could be better, who knows?
