Thanks Nikhil . Thats quite a lot info. But please clarify me. I pulled out specs of both psb and marantz
Marantz specification:
number of poweramps 7
Power Output (6 ohm, 1 kHz, 1% 1ch Drive) 180 W
Power Output (6 ohm, 1 kHz, 0.7% 2ch Drive) 140 W
Power Output (8 ohm, 20 Hz - 20 kHz, 0.08% 2ch Drive) 100 W
70% Guarantee o
PSB specification:
-------------------
Impedance:
Nominal 8 Ohms
Minimum 4 Ohms
Recomended power:
20 - 200 W power
MA RX6 specification:
----------------------
Impedance:
Nominal 6 ohms
Recommended amplification: 40125W RMS
Here nominal impedance looks higher in PSB. But how come its able to drive till 200w and MA is just upto 125W ? Am i missing something here ?
I have highlighted the specs that show the MA RX6 better suited to your amp
on paper.
Impedance of both speakers are more or less similar.
(Of course 8 ohms and 6 ohms are not the same but trust me this is fine)
Power Handling of the MX6 says 40-125W Rms.
This spec tells you how much power your speaker can handle for longer periods of time. Your amp has an output spec of about 140W (at 6 ohms) which means you should have a decent amount of headroom if and when needed. Since you have more power than needed the amp isn't working as hard to drive the speakers. This is a good thing. Typically results in a cleaner more dynamic sound.
What all this means is that your Marantz will be able to drive the MX6
better. Your amp can still the drive the PSBs but not as well as the MX6.
None of this tells you
how they sound. This is to me very important.
Here my preference is the clay ceramic PSB mid range drivers. I think they do mid range and vocals very well. The PSB tweeters are really good as well. But they do need an amp with grunt to shine. Try and see what they sound like with your Marantz if you can.
I have not heard the RX6 so I couldn't tell you. Needless to say they are quite well regarded. Do see if yo can hear them with your Marantz before buying.
Normally your speakers will be with you for a while so take your time to make sure you pick something you can live with. A bad choice in this area can be very disappointing and discouraging. Don't rush into this without auditioning if you can.
