Integrated advice for B&W 705's


I"m new getting into the HiFi wold and just starting to build my first system. 
I recently picked up some original series B&W 705 stand mounts (from 2004) and am powering them with a Marantz PM6004 integrated amp however I don't think it's a good fit with the speaker.  Just not quite as musical as I was expecting and the high end might be a little harsh (although very clear).  
Does anyone have any experience/advice for a good Integrated Amp to pair with these speakers? 
My budget is in the $1k range but maybe could stretch it a little for the right component and majority of listening is on vinyl. Thanks!

Before upgrading to ATC SCM11v2s, I ran with the B&W CDM1NTs (which are of the same 'family), paired with a used Musical Fidelity A5 integrated amp.

They paired wonderfully; the A5 had great grip, control, and grunt of power that the B&Ws responded well to.  The A5's phono section is pretty decent too.


Thanks for all your advice! 
You've definitely all given me a lot to consider and I suppose that all part of the fun & frustration of getting into this hobby.  I think looking into some room treatments might be a good first and lower cost step than a new amp & also see if I can find a local dealer willing do some demo's and at least it's a possibility to maybe find a good pairing.  Don't think I'm ready to part with the speakers as a first step.  I'm sure some tuning of the whole setup is still possible! 
My experience with B&W and electronics and cables in that price range and below is that the electronics and cables are usually responsible for the HF distortion. I am not, however, familiar with your current amp. 

I also have not personally heard that generation of 705. I assume its the model reviewed by Stereophile: https://www.stereophile.com/standloudspeakers/204bw/index.html
There is no indication that it is has to be bright. The CDM 1NT definitely was a real smoothie, kind of to a fault.

I have a Hegel integrated amp with my 707s and have also used it with my JBLs 4367s. It is very good in the high frequencies and great overall performer, in my opinion. 
My recommendation is Wyred for Sound.  I have two pairs of B&W speakers, Nautilus 802’s and Concept 90’s.  Both sound best with the ST500.  W4S also makes some integrated amps.
