For efficient speakers, how much difference does an amp really make?


I have ascend sierra RAAL tower speakers with 90-93db efficiency and 300W continuous power handling. I’m powering them with dual outlaw M2200 monoblock class AB/G amps rated at 200W into 8 ohms. It sounds good...but i can’t help but wondering if a different amp would provide greater clarity and low-end grunt.

I have been curious about an older adcom amp like the GFA-555 II or perhaps a parasound halo amp like the A23. 

To those who have had multiple amps in your setup, did you find significant sonic differences between amps, or is a subtle thing? I don’t want to start collecting amps, but I don’t want to deny myself the chance to improve my system further. Thoughts?

Try an integrated tube amplifier or preamp + power amp set. With those speakers, anything over 100 WPC RMS should work fine, and give you a lot better sound than your current Outlaw mono blocks. 
In your shoes, I’d audition the ACEYYK 160 watt Bluetooth integrated tube amp. Amazon has it priced at $1,010.99 delivered. If you don’t like it, just return within 30 days full refund. If it’s somehow defective return is free. If it’s a case of “well, I just don’t like”, then shipping back I’d in you. But you get the benefit of Amazon’s enormous discounts with UPS and FEDEX; or you can use a USPS flat-rate box if it fits. 
Mapman- I used to love those tech Hi-Fi catalogs and recently found a few scanned online - great memories of reading those as a teenager and lusting after the top systems with the multi track recording features.
