BRONZE UPGRADE

To celebrate the twentieth anniversary of the Q4 hifi rack we developed the Bronze upgrade that can be easily retro fitted to any Q4 or SVT HiFi rack or wall shelf. Bronze has a broader tonal spectrum and greater sustain that opens the soundstage of your system making it more musical and enjoyable without losing detail.

Central to all our research was extensive listening tests using the tried and tested technique of tuning by ear in the same way as the finest musical instruments are developed. In fact Bronze is one of several high copper content alloys used as a substitute for the more common types of brass to construct the bodies and bells of metal wind instruments. Even some instrument strings for acoustic guitars, mandolins and violins are wrapped with bronze. In addition to the distinctive appearance provided by the reddish-orange hue of bronze, it provides a broader harmonic response spectrum.

The main design features of the Bronze upgrade spike assembly are the SVT curve design of the top bolt and the rounded spikes that together encourage any residual mechanical resonance to flow and dissipate more easily.

The Bronze Upgrade assembly consists of a Top Bolt and Lock nut and then a small rounded spike and smaller locknut that screws into the top bolt – all engineered at our factory south of Bath. The upgrade can be easily fitted to the top shelf of your rack or Wall Bracket for the benefit of the source component placed onto that shelf. Any component placed on a shelf fitted with the bronze upgrade will have a noticeable improvement.

I originally got the King set & loved it so much I ordered another in Queen size!
Color: Charcoal, Size: King
I didn't add a picture because the advertised picture is exactly what it looks like (and my beds not made at the moment, lol). It's so soft, comfortable, cosey and warm. It's thicker and fluffier than I expected, but still very lightweight. The price was great for a king size bed with 2 king sized pillow cases! I love it so much I ordered a second set in Queen size, just to have the cases for my smaller queen pillows that go in front of the King pillows and to have the extra blanket as a cozy throw. The only drawback is it does snag easily on rings, fingernails, etc. (also another reason I ordered the second one to lay across the places that I've snagged & a few that were already snagged when I got them). However, it's so cozy that I didn't want to go through the hassle of sending it back and having to wait for a new one! I'm very glad that it was suggested as an add on when I ordered the mattress pad & that I chose to add it on. I'd definitely recommend it to anyone!

Comfortable and light
Team Name: Lightweight Comforter, Size: Twin, Color: Green
This comforter is nice and soft. I was looking for something lightweight and not too thick and this has been perfect as I get very hot during the night. Pretty color and low price too!
