Is Bi - amping worth the trouble?


Hello all...

I'm on the fence with the thought of bi amping. A big part of me wants to go ahead with it... the 'wallet' part says "Not so fast".

There should be lots of folks who've biamped speakers before... When it was all said and done, "Was it worth the time and expense?"

I'm inclinded to add a tube amp for the upper end of my VR4 JR's ... or any other speakers for that matter... though in any case and reardless the speakers, tube amp on top, and SS on the bottom.

...and then there's the thought of keeping two dissimilarly powered amps matched at the same volume level... and the added IC's, PC, and stand... it does seem to add up.

... and at this point, I'm thinking BAT to keep things all the same... and am not sure there, wether even that matters too much...

I sure do appreciate the input.

My system was passively bi-amped for a few years. At first I used a pair of SS amps, one on each speaker. Then, just like Blindjim, I wanted to add tube amps to the mix since I was enjoying having a tubed preamp. So, I sold off one SS amp and then added a pair of tubed mono-blocks that drove the mid and high freq. and let the SS handle the woofers on both. A horizontal configuration. The gains where within 1 dB, not perfect but a pretty good match. Now I was getting closer to what I wanted to hear, but there was still something missing. I could not put my finger on exactly what it was. Music sounded better, but still there was some lack of even delivery across the spectrum.

I kept listen and also kept researching. It finally occured to me that what I was really trying to do was compensate for the short-comings of the cross-over circuitry and in-efficiency of the speakers. I have sinced moved to a single, high quality single amp and a much more efficient 2-way speaker. The dynamics, clarity, speed, timbre, pretty much everything is much, much better. I can play the sweetest chamber music or the hardest rock or the fastest jazz and hear so much more musically.

Our listening preferences and system goals may be quite different, but I offer my experiences since it sounds like you may be looking for what I was looking for. Hopefully, you can find something useful in what I've written hear.

Best of luck in your search,

Blindjim, Do not let it go so fast, Biamping does work and to very good extent. I really like tube mids.
Just use the Xover in your speakers, they were designed with them and you should keep them, just add a tubed amp in the mids and highs, and an SS on the bottom, use a passive preamp like the EVS attenuators or the Luminous Audio preamp on the bass amp and let the tubed amp run free. The speaker xover will allow your speakers to do their job properly. You will win much more definition and dynamics on both bass and mids, you will get the "tubed" sound on the mids.

Since the power needed for mids and highs is much less you can do with a simpler push pull amp with a coule of power tubes per side, these have better definition to my ears that huge monster tube amps with 6 or 8 tubes per side, wich is what you will need if you decide to go tubes without biamping (these are much more expensive also!)
So finally from the preamp add a "Y" connector to the tube amp on one side and to the mids and highs; on the other connector to the passive preamp and the bass SS amp, that way you can adjust the volume needed on the bass amp.

Once you get the hang of it you can add a passive line level Xover (PLLXO) on the tube amp to avoid getting low freq. into it (say from 100hz up) that will help the amps a lot, more definiftion and dinamics again.

If you like symphonic music this is the best way to go!
If you are into girl with guitar music you dont really need biamping.

I am not biamping right now since my new speakers wont let me, and I miss it, I am thinking on adding a pair of subwoofers and a PLLXO on my tube amps....

Do try it!
It seems to me that an Electronic Crossover is the way to go. I remember years back I had 4 Carver M500 Amps that I used a Furnam Electronic crossover. It was a Pro type with 1/4 " phone plugs. With adapters I was able to make it work quite well. It had variable croosover, db slopes adjustments and Main and single level controls. I sold it and all the Carver Amps, when I thought I needed "better quality Equipment". (Still searching after all these years)
After reading this thread, I want to ask,
Is there any type of Audiophile Electronic Cross over today?
