Spatial Computer Velocity Bridge VB1

I have and they are really something special. I don't think you will use the word tweak to categorize them for very long. They do take time to break in. In my case 50 hours for the first milestone and about 125 to reach their full potential.

The impact of reducing RF/EMI and eliminating the tweeter ringing effect is immediate. You may thing you lost some "sparkle" in the high frequencies but it will return in a much more natural form with exceptional tone and balance between high and midrange frequencies.

This is just the tip of the iceberg in terms sonic benefits from my experiences with the product. Keep us posted.

You know what's really interesting about this product is where(from a system and component perspective) they implement the VB's. Right on the speaker cable terminals. No other product I'm aware of leverages this approach. There are other devices that address RFI/EMI at the source component level but this far down stream.

Good deal. Looking forward to hearing about their impact on the Paradigms with the Beryllium drivers. You really have nothing to lose given the money-back guarantee.

With this product being so new the jury hasn't even convened yet let along made a decision. I suppose their effectiveness will vary depending how severe high frequency ringing exists in a given speaker and the amount of RF/EMI in its environment. We all know how important impendence matching is at the source component level. Maybe this applies as well between speaker driver and speaker cable. There is a VB1 thread over on Audiocircle you will want to check out with more information.

Wow. The exact polar opposite of my experience. Mine were somewhat dull sounding at the beginning and I'm using solid state amps. Clayton's new line of speakers have Beryllium drivers. You would think if there was a problem with these types of drivers it would have been flushed out early on. I'm not aware of any restrictions on use of the VB1's but that does not mean there are none.

That's a real bummer. Do you have another amp to try just to help narrow down root cause? If not then the manufacturer should step in and help identify the issue.

I was referring to Spatial Computer, not ARC.
