Pros: source selection, swappable opamps, upgradeable tube
I'll make this a short review and just make several points.
- Excellent unit for beginners. You can use it so many ways, it's really an all-in-one.
- Build quality is great, I haven't heard of any dead units. Some minor problems here and there but they are quickly resolved.
- Superb support from the company. Fast and helpful emails.
- Upgrade and resale potential. You can use this as a DAC and amp and down the road get a nice tube amp hooked up to the tube pre-amp outputs on this device. Swapping the tube and opamps also upgrades the unit. I think resale value should be good due to the flexibility of the unit.
- I'm not disappointed with the sound quality of the unit but I only have a $60 portable cmoy amp and a computer sound card to compare it to.
Bottom line is it's an excellent product for the money backed by some of the best customer support I've seen from a company.
