While not the Tube Box S, I have a Pro-ject Phono Box S and can't say enough good things about it. It is mated with a Pro-ject RM5.1 SE and Dynavector 10x5 MC cartridge. This phono stage embarrassed my previous Parasound phone stage that I had. It is ultra quiet, provides a deep, detailed soundstage and great top to bottom dynamics. I would think the Tube Box S would meet or exceed mine. Plus the big feature on this phono stage are the dip switches for full cartridge loading, found on the Tube Box S too. You can precisely dial in any cartridge you may end up using down the road for optimum performance.
The tone arm found on the Debut Carbon will accommodate a wide variety of cartridges and like most of us, you will probably start upgrading the stock Ortofon Red. The Tube Box S will be ready to handle anything you throw at it, even low output MC cartridges.
Hope this helps.
