Bi-wiring and Bi-amping for Dummies (Well, One dummy amyways)


Thanks to fellow list member here I’ve learned recently some about my new equipment. Now about hooking it all up.....

Most of the new gear is pretty simple but there’s a couple of new twists I have no experience with. Bi-wiring and bi-amping.

Bi-wiring. I purchased a pair of Cambridge Audio Edge M monoblocks and a pair of

KEF R11 Meta speakers. The speakers will take normal wiring or bi-wiring  I now understand. I was lucky enough to contact Morrow Audio before they shipped out my new SP6 speaker cables and have the speaker ends changed to bi-wiring. 

The amplifier cable ends will have the normal two connectors while the speaker ends will now have 4. Pretty straightforward or am I missing something?

Bi-amping. Well, this will take another pair of monoblocks. That’s not in this year’s budget but maybe next year if it offers that much improvement. Does it add much improvement? Even when using monoblocks? Will it make the cables I just ordered obsolete? Will I need additional cables? Anything else I need to know? 

I’m sure bi-wiring and bi-amping are covered in the forums elsewhere but I’m trying to be specific for the brands of equipment I purchased. 

Your polite comments and opinions are valued, thank you.

@tcutter Watch that video link provided by ditusa and you won't regret the time used to view it. There is no sonic difference. But.... for me there's a huge financial difference. It has been mentioned here, buy the best speaker wire and jumpers you can afford. I bought Morrow Audio SP6 speaker cables. The same level of Morrow Audio jumpers are a grand. But having the speaker ends done up for bi-wire terminals only costs $150. No brainer. 

@mark200mph Ever since I switched a pair of old Harmon Kardon Citation 22 amps into monoblock mode from stereo, I was hooked.  Leaving everything else the same, the speakers disappeared. I was amazed!  

@ditusa I really appreciate you sharing that video link. It explains in simple terms why bi-wiring has no sonic benefit. In the video it looks like bi-wiring actually looks like 4 cables per speaker. The cables I ordered are only 2 per speaker but the end that connects to the speakers is split into 4 connectors. I think is a good money saving alternative with possibly a better connection than using cheaper jumpers. 

@fatdaddy2 Yeah, you got it right. Mr. Morrow is putting four connectors on the speaker ends of the cables. They will come with instructions and/or the cables themselves will be labeled. One of the many great things when you buy from Morrow is the very quick response time for questions sent via email, even on weekends and evenings. Mr. Morrow truly cares about his customers. 

Has @toddsyr effectively halved the gauge of his speaker wire by going with the 4 connectors at the speaker end instead of sticking with 2 at each end and using a jumper of suitable gauge and material? (If the length of cable from each monoblock to speaker is not very long (e.g., under 8 feet?), maybe this doesn’t matter?)

Bi-wiring is more money in the pockets of the manufacturer with no objective difference in sound.

 

Bi-amping fails every common sense test because it’s the same power from separate amps which also provides no objective difference in sound. But you do you.

While I agree that bi-wiring can indeed be a dubious experiment there are some speaker manufacturers that recommend it. Greg from Volti Audio comes to mind. I think he prefers running two sets of cables to each speaker though, rather than doubling the terminations on one end of one cable. Not positive about that, it's just how I've seen him do it.

Bi-amping is something I'll probably never try as I agree that it's better to just get the best amp you can rather than 2/4 lesser amps. If I had a cost-no-object system and an unlimited budget then I could see taking the plunge.

If you have very inefficient woofers like some big speakers do have it makes sense to have bi or tri amp.why does mcintosh  xrt 2k have tri amp even thier xrt 30 have multiple amp capabilities. Maybe they just want to sell more amps or they cater to some demand from customers. I love big kw amps as my krell comes to mind 750 mcx. The mcintosh 1.25 put out 200 amps with those big tranformers.enjoy the music. Power wakes some speakers up and let them hit close to x max.
