Amp, One Set of Speaker Connections Or Two?
I’m afraid the previous posters are correct. Bi amping requires 2 stereo or 4 mono amps (or 1 4 channel amp). As mentioned if your amp or receiver has an A and B speaker terminals it is still a two channel amp. It is not the same thing so if you want to bi-amp with the A 21 you will need two of them. I think you will be better off bi wiring them. I prefer using two separate sets of speaker cables and keep them separated from each other to avoid EMI interaction with each other and keep them off the floor as well. One of the main reasons for improvement with bi-wire and bi-amping is the elimination of the bad sounding jumpers that most speakers that are bi-wire capable come with. Omega Mikro sells pure copper ribbon jumpers that are a big improvement over most factory jumpers. At about $40 they are cheap to try. See them here: http://shop.mapleshadestore.com/Clearview-Biwire-Jumpers_p_1187.html Might just save you another $3000. The sonic improvements of bi-amping/wiring are subtle and I can think of many other upgrades I would rather make for $3000. I think you would need a serious highly resolving system to justify it. But as always in this hobby YMMV. Cheers. |
So here's how we settle this little argument. Its really very simple. You take your best shot at bi-amping. You add up everything you spent. Then you go on-line and buy whatever Synergistic Research cable you can find for that amount of money. Which one does not matter. New or used does not matter. Not for this. Well technically it does a little, only because new you have 30 days to return for any reason. Which is indeed a technicality. Because when you hear how much better it sounds than anything you can do bi-amping it will not be going back. But all your bi-amping stuff will be going in the dumpster. Because nobody wants it. Because bi-amping hasn't been a thing for like 30 years. Because you can always do better for less with just one good cable. Always. But please do not take my word for it. Don't argue it. Settle it. Go and listen. |
Millercarbon, and everyone here, Happy New Year. Miller, as always, you are very opinionated, and I disagree with you on this particular subject. I encourage, vertical, passive biamping, to many of my clients, and not once have they though of going back to a single amplifier, whatever speaker wire was used. Again, to each his / her own. Reading the entire description by Denon, they make it very clear of what they are speaking of, but, to a newbie ( we all were one, at one time ), it can seem confusing. As far a speaker switching on an amplifier, it is, of course, for convenience, as mentioned above. But, it has been my experience, that eliminating these switches ( electrically bypassing them, mostly on older Japanese and European made products, using as an example, the Yamaha M2 power amp ), there is plenty more SQ to be gotten out of the product. I would rather run several, separate, dedicated amplifiers, to specific sets of speakers, if this was a necessity. I do not see speaker switching on the majority of the top end amplifiers. In fact, when Adcom released the GFA 535 series II, getting rid if the speaker switching was paramount, in the sq upgrade, Adcom was looking for ( as well as better speaker binding posts, and other internal upgrades ). Sorry for going off on a tangent. To the OP, welcome ! Enjoy ! MrD. |
