ok I have answered my own question here .. I just brought the marantz mm7025 2 channel power amp I did not realise that it was part of marantz ref range I phone up a Hifi dealer and he said that the power amp is better then the pm8005 and would be good to use it for bi amping as I would get better detail out of my speakers and better tighter bass from the low end of my speakers so he said use the bass side of the speakers on the power amp and then use the pm8005 for the treble side of things and I should hear a big improvement as the 8005 has not got to do so much work . So it's been ordered from marantz and I got a free set of atlas Rca leads worth £125 free part of the deal I got the power amp for a good price too £699 normal £799 so will get it sometime next weekBlacksabbath25 said:hi i wanted to add a power amp to my marantz pm8005 but marantz only make the marantz mm7025 2 channal power amp which is more for AV use . i want to add a power amp for bi amping but stuck what to use with the pm8005 to do this . i do not want to buy mono blocks i just wanted to go the power amp road to do bi amping which power amps could i use to do this please .

i do like my marantz pm8005 and yes i was looking at the abrahamsen amp but its to much of a risk for me to takestevee1966 said:You've only recently purchased your PM8005 and have previously stated that you are very happy with it. Yet only a couple of days ago you wanted to replace it with an Abrahamsen, and now you want to add a ower amp.
What are you looking to achieve as a result which your current set up isn't giving you ?
yes i did get a good deal on it if it does not work out i can send it back i have 28 days to try itMark Rose-Smith said:Biamping in my experience is a right waist of your money,better with a integrated from a level or two above what you have.Prepare to be disappointed black sabbath as I was when I added a arcam p85 to my a85,unless you got the amp for a song it ain't even worth the extra cash for the extra runs of speaker cable.imho.
well have to try this things or i will never no i will have 28 days to try it if no inprovement i will send it back its not an issue but this power amp is useing the same amping power as the big brother marantz amp in the reference range which costs £1700 to buy as this power amp is part of the reference rangestevee1966 said:Spend what you want. I didn't mean to sound condescending. Just not convinced you'll hear a vast improvement.

We have the sole UK distributor for Abrahamsen as an active member on this site. You'll probably get one-to-one service from him.
well i was right about running in the marantz pm8005 even when everyone said rubbish you do not need to run it in . ok everyone has said its not going to work but i still going to try .philpot1001 said:i would expect any improvements in sound quality to be subtle, and as stated there will undoubtedly be expectation bias.....i would almost go into it with a sceptical attitude, bearing in mind you have a 14 day grace period. Dont be afraid of saying, this isnt working as i wanted it to and sending it back. That said if it works let us know, even if its just more volume (not sure bi-amping works that way or not, from what i understand it should).

Whilst I hope the OP finds what he's looking for in my opinion the only way to biamp economically is to get a preamp and two mono power amps. Using an integrated and another power amp just doesn't seem to give the same response.?
Either that, if you feel the 8005 isn't controlling you speakers well enough, then you should have auditioned first or you could simply buy a more powerful integrated to save on outlay.
the power amp i will be useing is the mm7025 which is meant to go with the pm11 s3 marantz amp as its part of the ref range so it will be mm7025 for the bass side of the speaker for preamp and the pm8005 for the treble side but i do not no this but i would of thought it would be blanced ?splasher said:I don't think there's any doubt it will work but I guess there's a risk that the sound will not be much better than you've got now given that you will still be using the PM8005 preamp (and the PM8005 power amp for the treble). Also, you may find the two different power outputs between the highs and lows make for a brilliant sound or not.
I guess the safer alternative would have been to trade in the PM8005 and add the new money to a PM14 or PM11 where the whole sound path would have been upgraded and everything balanced and designed to work together.
Hopefully it will be brilliant, though.

I did phone a Hifi shop today about this not the shop I got the power amp from a different shop and I asked them would this work they thought it would do I told them that I would be running the bass part of the speaker running though the power amp and the treble though the 8005 they said this was the best way of doing it . I said do you think I am wasting money they thought not as they think I should hear a difference and they could not see why not . I have never done this before I am taking a risk and I do understand that a better amp would of done the same job . What am I expecting even better control of the bass maybe deeper bass I do not no this not sure what this will do to the treble on this speakers . I was told by the shop today that both units should be well integrated with each other tomorrow the shop I got the power amp from will be letting me know the power amp in stock ready to post to me then I will ask more questions before they send it .. Can someone explain what's happening between marantz 8005 - power amp please my understanding is that the 8005 will be doing half the work load as its only got the treble to think about then the power amp is doing all the grunt with the bass channel is this right ? So power amp 50% 8005 50% share of the work load . Please do not pick me to bits help me understand the process of what I am trying to do your advice would be appreciatedDougK said:Sabbath, I'm not trying to pour cold water on this as I'm very interested in what you are planning to do, but is this actually going to work? Looking through the users manual it would appear that the speaker outputs on the 8005 will be by-passed when you press the power amp button on the fascia of the 8005 amp, therefore, rendering it out of the equation for any amping duties of the tweeters.
Maybe I'm reading the manual wrong, I dunno *pardon*
