If you are interested in improving the sound of your system, see if you can pick up a second Marantz PM 7001 cheaply and bi-amp instead?I have four lengths of cable I assume because the previous owner bi wired the speakers however given yor advice I will save my time and l leave them as they are. Thank you for your advice
If the speakers have previously been bi-wired then you have to make sure that the jumper bars that connect the top binding posts to the bottom ones are in place and firmly screwed down.I have four lengths of cable I assume because the previous owner bi wired the speakers however given yor advice I will save my time and l leave them as they are.

Whenever I see a query like this, I always wonder if the subtext is one of looking for improvement in a system?There can be a difference in bi-amping but as @larkone has said it's not as simple as connecting two amps to the speakers there has to be a power and gain balance. However it works with high end speakers and the Missions will not gain that much even with bi-amping. Manufacturers put four binding posts on speakers more as a marketing play rather than any real audio benefit.
If I had a pair of speakers costing over £2000 I'd consider bi-amping, sadly I don't and my speakers perform perfectly with a single wire. The Marantz is a classy amp and will take a significant upgrade in speaker quality but a nice system to get you started as it stands.
You can mix and match if the gains are similar and that would be determined by the specifications - if they publish it, otherwise it is 'suck it and see'. Arcam were always good at publishing the specs on their amp because they match their power amps to their integrated amps so that you can bi-amp with their kit - smart marketing move that.Just as a side query for anyone reading this Thread who might be considering adding a power amp to their system (and not an integrated as I initially suggested! ) - can you mix and match brands or would someone with, for example, a Marantz look solely at another Marantz power amp?
And how do you ascertain gain compatibility?
Speakers are so dependant on the room they are put in. That can only be tested by trialling them in your room which can be difficult when buying s/hand. The other option is to do what I did and go for something which you would believe to be a significant step up and hope that that proves to be the case. I went from Rega Juras to s/hand Rega RS7 on spec but it proved to be a significant upgrade but then the list price of the RS7s was three times that of the Juras. However the cost to me was the same as the new price on the Juras (£500).I am looking to improve on what I have what sort of speakers would you suggest, I don't want to get anything new would be looking at the second hand market, I was looking a dali oberon's but didn't notice any difference when listening to my missions. However if I can get more out of my amp I would gladly do so they sound pretty fantastic now.
