Is Bi - amping worth the trouble?

Okay. Your amp is fine.

Doctor Mark's reply, though considerate and correct, is just the tip of the iceberg. Feel free to experiment, learn and have fun.

Keep in mind when you bi-amp the Vr-4 Jr's you will still be using all the componants of the crossover just seprated. There for there will NOT be a gaint gain diffrence.
The important part is will you be able to detect where the low end leaves off and the mids/highs start.Also level matching and you will never be 100% sure if the correct levels are right. Put the money in a great single amp and bi-wire. I have Large von schweikerts and biamping wasnt the end all.

An interesting thing to try is to get the panasonic Sa-xr57 digital receiver. Which is a 100 watts x 7 and has a biamp function built into the unit. When biamped in stereo mode, it uses 4 of its internal amps for the bass section and one each to the highs. So it uses 6 of its internal amps when in biamp mode. All you have to do is run your speaker wire and push the biwire function and you are good to go for 300 bucks. It also has a great sound and has suprisingly great bass tone and slam and never gets hot.
You can also increase or lower the gain to the bass or treble, independant of tone controls if one seems hot to you. I know it is not expensive and no tubes are glowing, but you might find it interesting.

... got it. Thank you.

Got it. As I was listening to the input you posted it started coming back to me... the vertical thing was the way I initially thought to go... with the same VK500 w/BP amps. Possibly bridged... though not at first. then I thought better of that deal and figured on the tube + SS. Given the refresher/reminder course you were so kind to post, I see a bit more clearly that 'dream' could well become the 'nightmare'... and pricey. Thanks for the reality check. Another thing VK had told me about was the 'gain' issues. Even two 500's wouldn't be entirely matched exactly... and it was very doubtful that BAT could match them perfectly.

Well, gee. that's a drag. Oh, well... it was a nice dream while it lasted. I'm still dead set on trying tubed amps though.

'preciate the input on using the Sony rec., I've already got one, yet never thought to use it that way... mine puts out a bit more power than the suggested one, but i'm too disappointed now to give it a shot.

Bi amping given the info posted here, at least for me, seems way more involved than I had thought. But being an audionut, I thought the "bi-amping path" to really be the 'end all be all' in audio.

I more than appreciate the efforts, knowledge and experiences you have provided me. Thank you very much.

I'm using a hybrid on top and a SS amp on the bottom of my Vmps Rm 40's. Many people will tell you that at least with planar/electrostats that some tube magic on top can be magic. They were right!

I think the main advantage is to take the best qualities of two amps and use them there as I have. Another benefit however is reducing the amount of crossover components you're using. In the end experiementation is key. With our VS's I don't know as I've not heard them. You could also try various tube preamps. Please remember different tube preamps will sound widely different. Some not very euphonic like Audio Research to somewhat more, Conrad Johnson, to syrupy.

Biamping in my experience in my system has been the best way to go. If you haven't owned any tube gear it's a must try. A hybrid amp like the Van Alstine Fetvalves are excellent. The Blue Circle I had also was an outstanding amp, although quite expensive for the money. On the bass using this Rotel 991 is excellent. The bass quality is outstanding and I'm picky in that department. For under 500 bucks there's a few amps that will work well for the bass.

Best of luck and have fun!
