"Super Rectifier"

I acquired a Line Magnetic 519IA amplifier a few years back.  Lovely amp paired with my Tyler Acoustics PD 80 speakers, but I've often craved a bit more kick, a smidgeon more excitement.  After changing out the original tubes with the exception of the 5ar4 rectifier, I hit upon the Philips 5R4GYS from Upscale Audio touted by dozens of purchasers at the site.  What a difference!  The amp is quieter, more extended at the frequency extremes, and hits harder -- just what I was looking for.

Recently, I noticed a plug-in "Super-Rectifier" offered by Space Tech Labs.  Does anyone have any experience with this?  Seeing the difference substituting the original rectifier made, is it possible to up the ante even more with this product?

I originally thought you were referring to some sort of solid state rectifier.  But having checked out the net, wanted to ask if this is the "Super Rectifier" you are referring to?  Interesting  http://tmraudio.com/components/power-products/space-tech-lab-str-104-mk2-super-tube-rectifier/

Yep, that's what I was referring to.

I own and have tried all of the tubes mentioned except the Space Tech Labs and the Sophia Electric Aqua 274B blows them all away; this tube sounds like a Dac upgrade...

We need to consider the application for the rectifier.  A power amplifier will obviously presents a FAR different load than a DAC.

Aside from that, the 5U4G / 274B is directly heated, with far more voltage drop than the indirectly heated 5AR4.  The former have a more romantic, lush, and much looser sound, the 5AR4 has a much tighter, more focused presentation.  The performance of these tubes really differ in a yin and yang sort of way

So true; mine was in a tube power supply for my ModWright Marantz SA8005 Tube CD Player.
