Just wanted to share a little something that may or may not help some now and or in the future, it's concerning buzz and or hum. So I just got the Sonata3 a few days ago and I also replaced some cables, just shorter runs, not different brand, Blue Jean for the record. After the cable swap I noticed a hum, not crazy, but if you turned up the volume you could hear it, my rig is usually dead silent at any volume. My first thought, it must be the cables, this has happened to me before with Pangea cables in my rig, so it was the first thing I checked.
I spun the TT around so I could get to the connections, checked the ground while I was there, disconnected the cables, plugged them in and
before moving everything back around, fired everything up and gave a listen. No more hum, sweet, maybe something was loose, the ground?
Put everything back and called it a night. Today, when I fired it up and got ready to put some mileage on the Sonata, the damn hum was back, WTF! So I
turned everything around again, but this time I replaced the cables with another pair I had laying around, just to start eliminating things. New/different cables, fired it up, no hum..............
put everything back like it was and the hum came back.
So I spent some time researching, and I know about the Grado Hum issue, but it's never been an issue as best I remember, I found the same ole comments and complaints, "It's because Grado's aren't shielded", "change your cart or change your TT", that one made me laugh, but I get it. Then I came across 1 single post, nobody confirmed it, nobody commented back on it, but it simply said "
I had the same problem, but when I moved my amp about 6" away from the turntable the problem disappeared". I'm like, nah, can't be that simple, after all these years about the Grado hum, that's it? So first I found some pics of the M5's inside, sure enough, the large power supply sits on the left hand side of the case, my TT is to the left of the amp, so the cart and power supply are pretty close. Let's give it a shot.
I pulled the two apart as far as I could on my rack and fired it up, sure enough, no f**king hum. Just for the hell of it, I started to slide my amp closer to the TT, and I'll be damned, you could hear the hum come back and get louder as it got closer to the cart/TT.
So, another lesson learned, if you have a "Grado hum", maybe move your amp away from it and it will solve your problem, just something to store in your database just in case. I highlighted some parts of this in red so you can see the pattern due to the distance between cart and power supply, it made perfect sense
PS: I love this cart
