Part 1
Hi, and glad to hear from you again!

But less glad to hear that you still have that same issue!
OK, lesse, at high volume levels you hear distortion or bad noises of some sort right?
But at low volume levels it's fine right?
You have to be very clear and refresh my memory on what's going on, and with your newest gear, as I am a member at several Audio sites and I am very active in the discussions that I take part in.
I believe you now have a Yamaha receiver, the HTR6063. And your speakers are three Boston Acoustics CS26s, two Energy C200s, and two Precision Acoustic Subs.
And what is your source now, a Sony Blu-ray player?
*** What is it exactly that it does a high volume levels? And like how loud is it?
The better you can describe it and from which speaker(s) and how loud exactly you are listening at, the better I can pinpoint your issue.
...And stop spending anymore money until we know what needs to be done, OK?
Cheers,
Bob
