BMXTRIX,
I've just picked up on this thread. I have a Meridian G68, with Meridan DSP5200 L, R & C, DSP3100 surrounds and the Meridian SW5500 sub. I have never had any issues with them. I have had occasion to contact Meridian in Australia and HQs in the UK, and I have nothing but praise for the guys in support. Always speedy with replies to emails and always willing to help with questions. A shame to hear you have had issues, but I might have missed something... did you say you had actually owned any Meridian?
Yes the Meridian equipment is pricey and no, I don't have money to throw out the window. I have a wife, two young girls and a mortgage. But life is short and you need to embrace your passions and live it along the way.
Is the difference in audio quality night and day? Purely subjective, but to me, I can clearly hear the difference. For both movies and music alike, the sound is embracing and full. Is it worth 'x' times the $$$ of a Yamaha, Denon or McIntosh system? Again, purely subjective and in this case, all relative to what YOU value quality at.
For me, they are perfect, for you, I am glad you are happy with your Yamaha (or whatever system you may own).
