Thanks for your prompt response. May I ask what do you mean when you make reference to 'a cross over'? Also can you remind me what is the ohm level of the Castle Harlechs?Crossover separates the highs from the low frequencies.I do not know the ohm level of that speaker. Could be 8 or 4 ohms ?I would google this speaker manufacturer.
I have just returned home with my second Audiolab 8000p power amp (100 w per channel) .
The plan was to have one supplying the bass whilst the other power amp drives the treble of my floorstanding Castle Harlechs.
Before today I was successfully bi-amping the speakers using the power stage of the 8000a integrated amp and the 8000p. What I am now finding is that for some reason unknown to me it is only coming out of one speaker at best or coming out of both at other times but only the treble can be heard among some nasty sounding humming/buzzing.
The new (second hand 8000p) appears to be working fine (I think?).
I have one run of the Chord Company Rumor speaker cable connected to one power amp (bass) and the other run connected to the second power amp (treble).
I have 2 separate pairs of Chord Company Cobra 3 digital interconnects.
I am at present enjoying a nice piece of Miles Davies.
I now have an equal balance of both bass and treble coming out of both left and right channels of my speakers.
The only thing I am now confused about is that I achieved this by removing the speaker cable from the 8000p power amp and inserting into the speaker terminals of the 8000a which I was hoping would act as a sole pre-amp.
Is this usual practice or am I missing something.
Still not sure about the sound as although it is much louder and does appear to exercise more control over the music it feels as if it has lacked a certain degree of the smoothness that I originally had with the 8000a/8000p combination, might just need a few days to warm up and integrate into the system maybe?
Can you advise me of the best means of getting the most out of the 8000a & two 8000p's.
