VSA VR-3 Upgrades. Has anyone done them? Results?
I was wondering if any Von Schweikert VR-3 owners have ever performed upgrades on their speakers. I am considering this and I was hoping someone can share with me what that experience was like? Did you ship your speakers back to the factory? Or did you perform the modifications yourself? What upgrades did you opt for? Were the results worth it?
These are older speakers but, they are still sounding great! I am running them with a McIntosh MC275 IV. I am wondering if the driver upgrades will increase the overall efficiency of these and possibly, open up the lower mids a little more. I feel vocals could be a tad fuller.
Please share your experiences with me. Any and all suggestions are welcome. Thanks!
Below is the description of the upgrades as per Albert:
"The upgrade consists of two different modifications. You can choose to install any of them individually or do them both if you have the time and money.
a) New drivers that we designed to work with the existing crossover and wiring. In order to hear the increased detail and clarity, you will also need to install a set of damping blocks on the inside of the cabinet, which are supplied with the drivers. The damping blocks are to reduce the cabinet vibration and resulting coloration. They are made from artificial stone and are easy to glue onto the inside cabinet walls in the bass module. The upper module, if sand filled, will not require the damping blocks since the sand does the same thing. Our new 10” woofer has higher efficiency, for increased dynamic range and more bass weight when played at low volume levels. The new 5” Aerogel midrange driver has increased clarity and smoothness, while the new 1” silk dome tweeter offers an extra octave of “air” at the top end and also has far smoother detail in the upper midrange/lower treble. At the rear, our new horn-loaded Ambience Retrieval Driver with 1” silk dome and horn loading enables a far bigger and more dynamic sound stage. Just the addition of the new drivers is a huge upgrade and can be installed in about 2 hours per cabinet. The cost of the complete set of 8 drivers for both speakers is $1,200 and comes with silver solder, new gaskets, stone damping blocks, adhesive, and full instructions. You will also receive factory help on the phone if you require.
b) You will need to remove the cloth socks and reinstall them. If you socks are a bit worn and you would like new ones, they cost $100 for a pair.
c) New crossover boards with far superior parts is an option. Although not difficult to install, the boards will help you get to the next level of audiophile sound quality. The parts are very expensive and are from Europe, while the new wires attached are made from Single Crystal lab-grade copper, sourced from Delphi Aerospace. This wire costs $80/foot when the US Government buys it, but our price is less since I went to college with one of the guys at Delphi. The cost of both crossover boards, including the Delphi wiring, is $1,400/pr."
