^^Sounds about right, it takes about 50 hours to break in a new cartridge before it settles into it's groove.
On another subject I was perusing Canuck Audio Mart a few days ago and stumbled across a want ad for a 'stand alone Yamaha processor', the guy sold his old Yamaha receiver and missed the sound programs so much he wanted to fill the gap. I happen to own the flagship DSP they made and it's sitting in a box for the last few years, I answered his ad and we began a discussion. He asked for pictures so I took a few, then ran the DSP through it's paces and it looks and works as good as the day I bought it. Anyway I have the manual, remote, original box and the sales receipt, I keep everything when it comes to equipment makes moving it so much easier than if you throw out the boxes.
So he was interested, looked up the info on the DSP online and asked me to name a price, so I thought about it for a day and came up with a figure that was more than fair. And these are beyond rare, I've only seen one listed for sale in over ten years of surfing audio boards. In today's money it would be worth about $3000 brand new, it's also made in Japan not China. Anyway after I settled on a price he asked me to pay shipping/insurance/Paypal fees, which considering the money we're talking about was about 20% of the entire transaction. Being generous I told him I would split the cost down the middle that seemed more than fair to me, after all if it was $1000+ I would pay the shipping fees and everything else without complaint. He answered by telling me he changed his mind, that he would need another amp to drive the speakers.

He would have known that if he did read the online manual you need power for 2/4 front channels and for the rear channels. You can run the main/effect through one pair of speakers for the front end, I've done that for years and it sounded excellent.
One thing I hate about doing business on Kijiji, ebay, CAM and other online sites are lowballers. They are always looking for an angle and you end up wasting your time with them. I won't be answering anyone's ad like that anytime soon.
On the bright side now that I've unpacked my old DSP I'll hook it up and listen to my Classical again, the theater programs put you right in the middle of the orchestra.
