Amp change/upgrade for JBL4367 (94dB 2Way with Horn tweeter & 15" woofer)

Currently using Mcintosh MAC7200(SS 200W integrated).  Little soft but zero fatigue. Digital source only, listening mostly mid to low volume, vocal and acoustic music.
In mine mind : Mark Levinson 585; Pass INT250; Mcintosh D150orC47+MC452; C2500+MC452
Can some one has actual experience with the above amps give your impression and advise?

I'm sure some one with more direct experience with your speakers can add more but here are your specs. 
  • Sensitivity 1W @ 1m: 94dB.
  • Nominal Impedance: 6 Ohms.
those specs off hand look easy to drive.

You have a wide open world of amplification at your disposal and you don't need huge power 25wpc and up I'd think. 

So something to consider is less power and save some money. I really don't think you'll need 300wpc or close.

I have speakers that are 94db and 6 ohm nominal and run them with 8wps. for example ( granted i'd think 20-30wpc would be idea for my speakers)

I bet a Pass labs class A amp would be wonderful or maybe a Luxman Class A amp. 

No reason to pay extra for all that power if you wont ever use it. IMO

Something to consider.
