Hello,

here’s my simple HT set up;
Just replaced the crown XLS 2502 amp with ATI 1803 3-channel amplifier. I’m glad I did! Fronts & especially the center channel improved (center used to be ran by AVR)! ☺

VIDEO:
-Sony XBR-75X900E LED TV
-Sony UBP-X800M2 4K UHD player

5.2 SURROUND SOUND SYSTEM
-Marantz SR6012 AVR
-ATI 1803 three channel amplifier
-Atlantic Technology 642e SB subwoofers
-Martin Logan Theos
-Martin Logan Motif X
-Polk Audio S10 rear channel speakers

SAFETY COMPONENTS:
-Aircom T8 cooling fan system
-APC H15 power conditioner

SMART Components:
-Echo Dot
-Logitech Harmony Hub
 
Congrats on the new amp, and nice setup.

thank you!
The Crown is definitely way more powerful since it has 3x more wattage.
But the ATI is more musical. I wish the ATI just had more power since it’s only around 270wpc @ 4 ohms.

Amperage may ultimately have more impact on sound quality of M-Ls than wattage. IMHO this is why Pass amps even the lower "wattage" XA30.8s are so synergistic with e:stats. I WILL say that as I have gone up in wattage within a series SA, Aleph, XA the sound does relax more. That being said, the XA60.8s have been measured at peak power of approximately 300 watts vs their nominal 60wpc.
