Currently have a Yammy and am about to replace it with a AVR3802. Due to the "Enhanced Pro-Log" on my current amp I have plenty of speakers for the Denon, but was after a few opinions as to whether I would get anything like the improvement in sound I could expect from the upgrade. Intended layout; Front- Wharfedale 505.2 centre- Jamo Centre 100 Surround- Mordaunt Short MS 310 Rear Centre- 2 x B & W Solid TEAM Sub- Yamaha YST-S60 Its a real mixture mixture I know, but its been aquired over a long period of time. If it is a real pile of cr@p am I better just upgrading one element or putting up with it until I can afford a complete package? The KEF Eggs really appeal !!
