CHANDOS label...

I think the Chandos' catalog is the best reason for their existence. They have recorded a lot of music that is overlooked by other major labels and is worth exploring. SQ and performances are good to excellent (like other most other labels).  

A lot of good recordings, agreed, and excellent repertoire.  But overall are they better than, say, Hyperion?

Certainly not better, but at least complimentary in their catalog. On average, SQ wise, Hyperion might be a tad better. In comparison between the two, I would say that Hyperion might be a bit more neutral and Chandos a bit more rich. Unfortunately that richness might just make some of their CD's less transparent and or reverberent. 

I like Chandos records.  I only have a couple of them, but no complaints.  Fine fidelity.  Fine performances.

good label
