This is both self-serving and sincere. I began my vinyl era about 10 years ago with the NAD PP2. I had nothing to compare and was happy for years. I upgraded about 1.5 years ago to the Project Tube Box DS and loved the improvement. I have been building an ARC system and picked up a PH5 a few weeks ago and again loved the improvement. My Project is for sale here. It retailed for $700 when I got it for $600 and now it retails for $400 after discounts. I have it listed at $299. If you don't want to mess with mine, pick up a new one for $400. I think you will be pleased. Good luck!
