Von scheikert VR4jr what are you using ?


I just got a new pair and I am wondering what amp would be best. I have a Cary SLP-98F1 as a pre and currently using a V12 to drive them. I have a BAT VK-200 as a spare and I am going to hook it up this week end, to see how it sounds with the SLP.
I originally heard the VR's driven by NuForce 9.02 mono's, they sounded fantastic. They were in a treated HT room, which is totally diferent than my space. Right now before break in they sound good but I get don't get close to the sound I heard in the demo room(of coarse I never do). I can only come out about 1 1/2 ft. from the front wall, so I'm pretty sure that is where I lose a lot of the spatiousness.
I am curious to see what other VR4jr owners are using and what they have heard elsewhere.

To be honest, I've never heard the VR4JRs Demoed at a dealer or show that sound anywhere near as good at the do in my home; and, I have some compromising acoustic problems in my listening room. Nevertheless, I started out driving my JRs with a 300 W/Ch Bryston 4BST and they sounded very, very good; as I said, better that any dealer Demo I'd heard. However, when I switched to the new Mcintosh MC270 75 W/Ch tube amp they really came alive, especially with tube upgrades from the stock Chinese-manufactured tubes. So much so, that I no longer feel the need to upgrade my amp anymore.

My JRs are setup with the front baffles about 38" from the wall behind them and the rear ambience tweeter set at 2. Setting the rear tweeter higher will get you more a sense of spaciousness but will blurr the sound somewhat. Lower settings with give you significantly better imaging. You really need to experiment to determine what setting is best for your room. For me, that took quite a bit of time. I'd replay certain music, resetting the rear setting, and do this back-and-forth for a while. But found that once I found a setting I liked to leave it that way for a few days of listening. Then change it + or - a few days later and decide if I liked the difference. I needed a few days to get use to the sound at one setting before I could determine how the + or - change affected the sound.

The JRs didn't reach their peak until they had at least 500 hours on them; after the break-in they sound SIGNIFICANTLY better - hard to believe. Also, be certain to load the bottom chambers with 40-50 lbs (@) of lead shot for the tightest bass and most dynamic impact. Also, I'd strongly suggest replacing the stock speaker spikes with some decent brass spikes for greater clarity from the speakers. Also, set aside the cable connector between the upper and lower units and bi-wire the speakers for absolute best results. Finally, if you're willing to do some very simple tweaking, remove each driver unit and coat the speaker/driver contacts with Walker SST (or the SST Extreme) silver contact enhancer (as well as all the other contacts in your system) and the JRs become amazingly fast and dynamic. This is really easier than it sounds and well worth the moderate expense and effort.
I agree with Jgiacalo on the break-in, base loading, and biwiring issues. I have used a few differnt amps with my JR's which I have had for 1.5 years now. I have used a Pass X250.5, a Forte 4A, a McIntosh 6900 integrated, and am currently using a bel Canto Evo 200.2. All have sounded great, but different of course.

The 4JR is one well balanced speaker that when properly broken in and set up will sound mighty good with a lot of different electronics. What it will do is let you hear the differences.
Jgiacalo- what spikes are you using? I have a pair of Vr2s and would like to replace the spikes. I was looking at some Mapleshade ones but being able to rake the speaker back is a must. Are yours height adjustable?
I'm running Channel Islands D-200 monoblocks with my VR-4jrs. Dusty usually uses Von Schweikert speakers in his demos -- here's a photo of the Channel Islands Audio / Von Schweikert room at the recent HE2006 show.

I'm using a bi-wired pair of Gregg Straley's "Reality Cables" and the set up, while still breaking in, sounds fantasic.

Good luck in your search.
I'm waiting for a pair of VAC Standard 90 mono blocks to arrive. Albert has paired VAC equiptment with his speakers
at CES. Kevin Hayes of VAC is very enthusiastic about the JR'S with the mono blocks. I'll weigh in when I get things set up. I have Silversmith wire all around. Before this latest upgrade I had been using an integrated ASL and things sounded pretty darn good with the JRS.
