Questions: I'm using mainly Klipsch loudspeakers for everything so far... I'm wondering if rs-42's
would be a nice fit for the current amps. Or maybe I should go bigger/smaller... havn't heard these yet. *suggestions???*
also - I'm going to need an external amp to power the front pressence and rear surround backs.
Anyone have a good suggestion for an amp that will do what I need for this?
This will be my first amp. awwwwwwe.
If you're going to get any external amps, my suggestion is to get a pair of two channel amps (Emotiva XPA-2 x2 is a good starter set) and bi-amp using those, while letting the Yamaha's internal amps take care of the speakers that it can handle physically. You'll get far superior results bi-amping externally and letting the Yamaha handle the lesser powered speakers itself.
As an added bonus, going external and using each XPA-2 (or the amplifier you end up getting) for one speaker (Left channel for bass array, right channel for mid/high array for a single speaker, for each amp), you eliminate virtually all crosstalk. Since your speakers' own crossovers will do the work of filtering the signal either way, you may as well get more power out of it.
As for me, I was kind of bummed as I just read the A3000 manual right now and saw this:
■Connections of speakers
■Assigning a speaker configuration
Connecting surround back speakers to an external amplifier enables simultaneous use of front speakers that support bi-amp connection and surround back speakers.
FRONT jacks Front L/R speakers (bi-amp)
CENTER jack Center speaker
SURROUND jacks Surround L/R speakers
SURROUND BACK jacks Front L/R speakers (bi-amp)
SUR.BACK (PRE OUT) jacks External amplifier
(for surround back L/R speakers)
SUBWOOFER (PRE OUT) jackJ3 Subwoofer
Power Amp Assign 5ch BI-AMP + SB
I guess this answers my question of whether or not the pre-outs are also set for bi-amp (bass for front L/R and mid/high for SurrBack pre-outs). They are not, sadly. So for me this leaves the A units' SCENE functionality as the sole reason I'd want to upgrade. Unfortunately this makes the Integra DHC-80.2/Onkyo PRSC-5508 look a lot more attractive to me.
Guess I'll know for sure when the A3000s hit the B&Ms here in the bay area.
