Advice on Integrated Receiver


I currently have two Monitor Audio Silver 300s.  I have a Cambridge Audio CAX81 (80w/ch).  After reading the reviews, the speakers sound a bit underwhelming.  I have a Rega P6 turntable hooked up for most of the audio content.  In looking at the Max Wattage for the speakers I realize perhaps the amplifier isn't letting them breathe enough?

The speakers are rated at 200w max with recommended 80-200w RMS.   Am I way off base in thinking I'm underpowering these?

What integrated receiver would you recommend to really drive these?  Budget under $5k

Tell me the Luxman L-509X is overkill and that I wouldn’t notice a difference. It’s a beauty, but surely there are diminishing returns. I found a H390 at $4,300 and a L-509X at $6,950. Both on USAudioMart.  

Keep in mind my endgame is ditching the MAs for 803s.

The Luxman should be stunning. I haven't heard the L-509X, but I own the L-590AX, which is everything I could have imagined, and more. I wouldn't ditch the speakers before you hear the new amp.

My speakers are Paradigm Signature S6’s. Again, I’m running a little bit different amp, the 590AX is Class A up to 30 watts.

The 509X you’re looking at is 120w/channel into 8 ohms. Here’s a review from a few years ago at Stereophile.

 

I haven’t heard it, but it was pretty well covered when it came out.

Take your time, sell/buy 1 step. At a time, to see if the sound changes. 
 

good rca  interconnects, won’t give a revalation, but there’s just something about tweaking my stereo once every two years or so , just for an excuse to not vacuum floor, or help with supper, or do dishes,

why you think it takes me 2 1/2 hrs to change my oil in my truck?

go slow at first, , definitely try a 200W rms amp with your speakers, no such thing as too much power' that’s so,e thing these whiny snobs belt out, because they  know they dumped thousands on a 6 watt hamster fart, which can’t even drive a bookshelf speaker without clipping at every crescendo and drum fill. 
 

my speakers are only rated for I think 250 peaks, so you just have to not get too loose wit the Bushmills, or the volume will go up and u will wake up to a fried tweeter or resistor in your crossover. I have 650W rms monoblocks going to my 250 iW  max rated towers. So effortless at every note , kick drum, acoustic guitar,, Gary Moore’s guitar , even vio-lence, abattoir, Angel witch, bitches sin, no strain what so ever, smooth sailing from now on.  
having that much headroom istkeeps everything stress free and sounding full and lush while you just sit back with a dram and enjoy your fav bands. 
 

btw, nice system you have, love the speakers. 
enjjoy the hunt. I always do
