G'day all, I built a breadboarded VSPS a long time ago and give it use every now and then.

I have purchased and/or built a number of different phono stages that are all excellent, but can somebody please tell me why the VSPS sounds so musical?

I'm presently spinning David Bowie's 'Space Oddity' album and it sounds so musical through the VSPS that there are almost tears in my eyes! Regards, Felix.

In that case get something just to make it work, and when the DIY bug bits you again and you can afford it get a bigger one. You are in for a nice surprise

Simplicity at its best I really love that phono too.

Money is not really the problem. I'm a stubborn guy, and if my own logic tells me it can't be true, then I need to make my own experience. And yes, in the long run it's darn expensive to learn the hard way, but it's also more fun.

And, it's always nice to have spare parts in the drawer (at the moment I have an old unknown DIY phonostage with PSU, two class D amps with heavy toroids, four 8" philips full range, eight 10" woofers, two Mark audio full range, two small woofer/midrage, two tweeters, one small yamaha class d amp and bits and pieces), so if a 100 VA transformer really is that much better, then I can reuse the 16 VA to something else

I can confirm that for some reason The VSPS (and few other) single op-amp RIAA preamp does sound very, very well compared to some two stage projects.

Also bare in mind that most integrated amplifiers (even those "labeled" as high-end) use the cheapest way of processing the phono signal. They use poorly designed power supplies and general purpose op-amps.

100VA is overkill. IMHO the main reason for using a bit oversized transformer(toroidal ones) is the marginal differences in the price tag for ratings up to about 50VA. That's why I always use the highest VA rating that fits my budget and enclosure

Overkilll... another weird word that is often used in such discussions...

What would make you feel better.... Shooting your enemy with a pistol? Or evaporating him with a bazooka?

Adequacy and overkillness is a matter of personal taste... try and you will see... the difference is there...

Neither...

I prefer the sniper rifle

Which in DIY audio terms translates as(applied to RIAA phono stage) - large enough transformer capable of supplying three times the current consumption of the stage and a dead silent voltage regulator(discrete).

Again you are referencing a random multiplier that seems logical or practical.

Of course there are diminishing returns, which make the difference a matter of personal taste and economic practicality.
But what I am saying is that if it is overkill or not should be a matter of testing the impact it has to the sound.
