Yes in a nutshell. The rec out of the Azur would go to the line in of the power amp. But.....

45wpc should be plenty loud enough for domestic use. The problem may well be elsewhere. Check the speakers connections are correct. Is it too quiet with all inputs or just one? What speakers are you using?

Not too sure where he mentioned quiet. However you are correct in that the amp should be sufficient for most but the more inefficient speakers in a normal domestic environment.

Perhaps the OP could add a bit more info as to why he feels that he needs more 'power'.

I don't think you have a pre-out on the CA 351A for connecting to a power amp. As above why would you need more power? Maybe you have insensitive speakers?

Or.......

You could try a pre-amp or mixing board with volume controls and increase the out put on your source.

Small increments though and start with the amp volume set low.

Also,cheap freebie interconnects can have an effect on volume output in a negative manner.45 watts should be plenty of power for a decent volume output if your speakers are in the 88-90 db range at 8 ohms,below 88 and they might be starting to ask some questions of the amp.If the op told us the speakers he is using,it would help,but as for increasing power output,I think an amp upgrade would be the logical option

Got a pair of monitor bronze 5 in the lounge and a pair of B&W in the kitchen

 

[Mark674]

Any suggestions what to buy

 

[macdiddy]

go for a 651a, 75wpc should make a difference.

[Mark674]

And use the 351 as a pretty amp

Hi Mark,

Do I understand correctly that you drive two pairs of speakers off the same amp (together)? If so, that might give your amp a hard time!

 

[Mark674]

Meant pre amp

 

[macdiddy]

upgrade from the 351 to the 651, this will also allow you to add a power amp if required in the future.

Was thinking of adding a pro next power amp

...wouldn't provide any method of controlling the volume because his current amp's rec-out doesn't go via the volume control.

Maybe you have insensitive speakers?

The best way to test how sensitive they are is to call them rude names and verbally abuse them. If they don't flinch then you know they're insensitive.

Sorry.

 

[MajorFubar]

PMSL!

Sorry, I'm easily amused.

+1 if you are driving 2 pairs of speakers (i.e. 4 speakers) from a single 351A two channel amp, its a mistake.

Sorry. 

...and if they still block your path, when asked to move, they have a high level of impedence.

When I tried that amp in a hi-fi shop with a pair of Roksan K2 TR-5 speakers (88dB), I had to turn the volume knob to 3 o'clock to get barely moderate volume out of them. And it didn't have much more to give, it might have been clipping. The HF were painfully bright.

And even more impudence

Give them a gentle push with one finger. If they fall over they have very little resistance.
