Peter :
Do you mean the Beocord 9000?
Yes.
Peter :
If so, you need an amplifier.
What kind of amplifier would you recommend for BC 9000? Solid state or tube?
I've seen a brand new tube amp made in Taiwan for around $250 from LA Audio.
My use for BC 9000 would be primarily for recording and playing back my own tapes for trading research. I've learned over the years, audio medium used for its content, such as book on tapes, not how the content is delievered sonically, i.e. music, I actually prefer mono over stereo, which can be really distracting over absorbing the idea delievered through sound.
Peter :
The Beocord 9000 produces Line Out constant level so you cannot really connect loudspeakers directly to it, even active ones.
I guess this means active speakers are out.
Peter :
The obvious amplifiers to use are the Beomaster 8000 and 6000 which match the Beocord, allow remote control and both have very good performance.
Can I just use an amp instead of receivers? I don't really need the rest of baggage BM comes with. For me, remote would be really nothing more than a gimmick.
Peter :
The 6000 will be cheaper and some people find to be a sweeter amplifier. Both are complex, the 8000 in particular though. The 8000 has a massive power supply and is very heavy! Best collected rather than posted. If you like the RL series, RL140s are ideal. At risk of being controversial, I don't think any of the speakers you mention are the very top of the tree from a performance point of view - and I have most of them! You don't need B&O speakers of course.
What would be your recommendation for mono speaker?
