A quick update on my experiences with Renolabs. Overall, very positive.
1. I ended up purchasing an upgraded rev of the reclocker provided on the Renolobs website. The new version includes an OCXO clock and LT3024 regulators. Cost is $400 + shipping.
2. The reclocker arrived from Vietnam in about 1 week.
3. Sound quality is very good. I heard a clear improvement in clarity, smoothness, and dimensionality.
4. Communication was good. It's not perfect due to English not being a first language, but more than adequate.
5. Overal, a positive experience. How does it compare to other reclockers, I can not say. I have no practical experience with others.
