Review: VPI Magic Brick Tweak

Category: Accessories

This is an $80 block of wood with a VPI logo and filled with transformer laminates. Not too impressive, eh? Well, the appearance of it is quite nice, and looks a lot better than my DIY dampeners. Also, it's not easy to enclose laminates in a block of wood without having them rattle. Basically, you pay for looks and quality, not parts. And for many audiophiles, that's enough. How do they sound? compared to nothing extra dampening the chassis, these seem to improve imaging, as well as removing some harshness from the sound. It simply sits on top of your devices and absorbs stray fields, helping the internals operate in a better enviornment. These effects were to various levels with the Amp, DAc, and pre. The amp benefitted the most, with a fair improvement in grain reduction and imaging, though the A100 is no slouch in these areas. I suspect that the mere size of the electrical fields in this device account for the greater effectiveness. The preamp benefitted nearly as much, and in the same way, though again, it was no slouch to begin with. The improvements in imaging were both matched with my own Marble dampeners, though the grain reduction wasn't there. On the DAC, there was a tiny improvement in imaging- the steel chassis, rather than aluminum seems to have prevented any of the absorbtive benefits of the Brick.
For those who can afford it, this is an expesive tweak, but a worthwhile one.

I have used these for years but in my day they were 50.00.
I use them on top of the outboard dual mono power supplies for both my Modwright Sony 9000es and my Musical Concepts Epoch Signature 7. Yes it's like taking a picture that is out of focus just a bit and focusing it.

I bought a few VPI bricks years ago and also had good results with them on top of the transformers of a variety of amps. I read in one of my father's old MSEE textbooks from the golden age of hifi in the 50's, that a block of iron or other magnetic material in proximity to a transformer will improve coupling action between the primary & secondary windings. So I attribute the improved sweetness and weight added to the sound by the bricks to this scientific explanation, rather than to dampening or RFI absorption effects speculated by various posters.

Has anyone every used the VPI Magic Brick on power conditioners or isolation transformers? I'm thinking about putting 2 Topaz isolation transformers next to each other and was thinking about using the VPI Brick on both noise isolators. Thanks

For a large AC line transformer like the Topaz I would lean toward a heavy bag of microbearing steel available through eBay or a foundry supply company. The magnetic properties of the steel shot will improve coupling of the transformer electrical fields in the manner of a VPI brick. And since microbearing is much more physically reactive than a VPI Brick, it will also do a better job of absorbing vibration. Finally, it's cheap.
