Q acoustics harsh high end


Please help.
Just bought a Pioneer network reciever and a pair of 3050s. I realise this isn't top end equipment but at any sort of volume the upper frequencies are harsh,  very noticeable on female voices. The last system I had was started back in the late 70s with a pair of MA4s, then a denon amp, 50W I think, then I added a mid range Marantz cd player.
I remember having absolutely no issues with the sound quality. I have tried placing the system in a different room. I have tried a different amp (Marantz 63KI). I have tried a different Cd player but all sound the same, bright, harsh top end. Im begining to think it's the speakers but the reviews are almost unanimously brilliant. I'm wondering if I should get some second hand MA 352s
Any advice would be welcome

Thanks Erik for the tip. I have just listened to Hounds of Love by Kate Bush and listening close to the speaker highlights the problem even more. Kates voice is very hissy, each word seems to have ssssss on the end, very unnatural. Im wondering if this is typical of modern speakers and I should source something second hand.

Sorry, the speakers I grew up with were Monitor Audio MA4s, from 1976. I guess you would call them a classic design with a 8" KEF bass driver,  25mm tweeter and a port. They were a couple of hundred quid at the time, so quite pricey. The 3050's are Q Acoustics and there the ones that sound bright and hard to listen to.
Many "modern" speakers sound that way.  It's the fashion these days.  You'll need to look out some of the few remaining more forgiving brands.
Be patient.  The sound will likely improve,
over time.  You may consider using the XLO
Test and Burn-In cd.
