What's Next

Many thanks. Appreciated.
Agree, the final decision will come from somewhere between my two ears but most importantly from the how do I FEEL when I hear them playing the music I like. I am listening to Ernest Rangling - Soulful Moments as I type and the Lyngdorf/AR9 combination is close to heaven, but my speakers are old and want to tip my toes into more modern speakers. Have had B&W-703/803, KEF Ref, Gershman, TDL, SF Cremona, JBL Ti, along the way. The demo of the 300 did not leave me with the feeling I thought they would stir but only with the feeling that my AR9's are great.
I guess I would wait for the PL500 to arrive this week to go back for a session armed with the same test discs and my Amplifier. I dont think i would struggle with the Bass/Mid, just the really top end(Tweeter) - I listen to all genres and some caribbean music need the really high top end to do them justice which the 300 did not give me. I really hope the voicing is better in the 500.
Thanks....

What are the other components in the system with the PL500s? The PL500s are voiced on the slightly dark side compared to many of todays highly talked about speakers. In my system the PL500s have as much detail as any other; however it doesn't hit you in the face. If you like a forward sound, you won't like the PL500s.

I realize that you only listened to the PL300s. My question should read, What  will the system consists of when you audition the PL500s?

My system 1 uses Musical fidelity KWP/KW1000 setup with a Linn Majik streamer and nuforce DAC for CD. Also AAphono for vinyl. AR9 speakers. System 2 is Lyngdorf 3400 driving JBL Ti5000. Schmitt Mani for vinyl.
