Beovox S45, S50, S80 - Sound? Value?

17 replies

It is probably a pretty good amplifier - and quite frankly better that some B&O ones! A lot of Sony products are excellent. It will not have the design of a B&O though.

Depends really what you want. A Beomaster 6000 is the obvious choice and, when working, is excellent. It is 75W a channel. The 8000 is the most powerful - 150W a channel - but harder to find. If remote control is not important, the 2200 is a fantastic and very cheap alternative. After that, think about the stacking systems - 5000, 5500, 6500 and 7000. Enough power and very versatile remotes.

How many watt per channel do you think is necessary to power the MC120.2s?
Work perfectly well with 30W. Remember that most listening involves 1W or less! If you like listening at loud levels, having a powerful amplifier allows this without clipping. Most B&O amplifiers have lots of headroom - the 2400 is rated at about 30W but can produce peaks of 75W.

Really? I had no idea that you could run speakers on that much less power than what's specified. I suppose the specs are a maximum, not a nominal. I'm actually thinking of grabbing an Harman Kardon PM-640 amp to drive the speakers. Harman Kardon styling is great... like B&O, they were a company far ahead of their time.

Well, guys. Thanks for your help. Not sure who's going to see this post, but I thought I'd say a few things.

The bidding for the MC120.2s ends in a day, and I think I'll probably get them. In the meantime, I've been searching for and reading about all manner of B&O things. When I thought about getting new speakers, B&O never really entered into my mind as a brand to buy. However, after looking at all their vintage products and reading about people's experiences with them, I've decided to start collecting vintage B&O.

I'm looking forward to posting on this forum in the future, although how much I have to contribute, I'm not sure. I don't have a lifetime of experience like other members, as I'm just a poor university student. I'm looking forward to getting to know everyone, and I'll definitely let you guys know how my first experience with a B&O product goes (I'll include some pictures as well).

Hi Andre,

I just wanted clarify what Peter said about the 1W listening.  When we say an amplifier puts out 50W per channel, the majority of this power is actually dissipated as heat.  So even if you have a 50W amplifier playing at full power, there may only be less than 10W of electrical power actually reaching the speakers.  When Peter said 1W, he meant 1W of power actually going to the speakers, which means the amplifier could be actually using something like 20 W.  This was still a morbid simplification, but I just wanted to clarify that there's a difference between the two wattages.

Thanks for that clarification, Austin. Some people talking about older amps putting out 'real watts', and being more powerful per watt. Is this heat dissipation to do with the apparent difference between older and modern amps, or am I oversimplifying things?

Oh, and a little update on my speaker situation, in case anyone is interested. The guy I was buying them from took both pairs down from his attic (I bought a pair of S80s and a pair of MC120.2s), and the woofer was ripped on the S80s. Also, the wood had been cracked on the casings. He said he almost cried, seeing the speaker like that. Guess he really loved them. So anyway, I think I'll forget about the S80s and just take the MC120.2s.
