Von Schweikert VR-5SE

Mfontana,

Just to let you know, I heard the VR-4SRs driven with the VAC Phi 110 too at a dealer, and although it sounded wonderful, the VAC wasn't able to drive the SRs two woofers with authority, somewhat wooley and undefined bass. I own the VR-4SRs, and have a solid state amp. A more powerful solid state amp can grip these woofers with more authority and laydown the bass as it was meant to be heard and felt. I suspect you are having or hearing the same effect from your VAC/VR-5SE combo. Try to use a powerful solid state amp on the woofer modules, don't forget they are 4 ohms. I'd say at least 300 minimum of high current watts to make the woofers sing. Give it a try, you will be amazed how good the bass is from the VR-4SRs/ VR-5SE.

I agree with you 100%, In my earlier post I mention I'm now biamping using the Vac Phi 110 for the top and the Spectron MusicanIII for the bass bins I think the Spectron delivers 700 or 800 watt's into 4 ohms.

Mfontana,

I bet your bass is so much better than using the VAC alone. Cool, nice to hear. Enjoy !

Hi all hey Mfontana
I have the BAT 75se/VR5se set up and wanted to also give bi-amping a try. But ss amp would have to have volume controls so I could match it with my tube amp. What Mfontana are you using to balance out the two amps?

Moemoney,
My Vac has a gain of 38db, the Spectron has a gain of 28db.
From my Pre. I run two sets of cables one set to each amp. If left alone there would be a mismatch in volume the tube amp would play louder than the Spectron. To equal this out I put a pair of Rothwell 10db attenuators on the RCA's right before they enter the Vac amp. This did the trick, anyone who has heard the speakers can't tell there are two different amps running them " they are seamless " I thought the speakers were good before this change but they are now at another level. I bought the attenuators on Audiogon for i think $69.00. My friend has the VR5's also and was not as lucky with this project. He has the Atmasphere Ma1's and tried to mate them with the new PS audio amps but the speeds were off, the OTL's were just to fast for the PS audio amps. I am going to try and get him to contribute to this post, he knows far more than me on the subject.
