The AVM-20 is not going to be 9 years old most likely. It will also crush most other pre-amps sonically, especially an old Onkyo. Check out a B&K or Sunfire also. The budget solution is Outlaw.
Help to upgrade my surround processor
Here's the short version. I have a TV with composite and S-video inputs only. I also have an old (at least 15 years) Onkyo ED-301 Dolby Digital SP. I only watch a movie a week. My sources are DVD and Laser. I can't change my TV as yet, so the S-Video is OK. But I imagine the chip in my unit (motorola 24 bit dsp 56009) is basically a dinosaur. How can I get some better sound and upgrade? I imagine I just can't upgrade my chip. Sound is my primary consideration. My problem is that I hate to buy an Anthem AVM 20 which is a 8-9 year old unit and the newer Anthems are too pricey. Does the v2 2.21 upgrade sound good enough compared to today's chips? Otherwise Rotel, Sherwood, Outlaw or maybe a Cary 6? Thanks in advance for any help.
