Help with Classical Music Record Labels.


Hello,

I have had some good and some bad experience with classical music records so I would like to know what are your favorite recoding labels for Classical?
Which label will always guarantee a great listening experience?
So Far for me Deutsche Grammophon, Decca and RCA Victor are  the best but I am sure there are many others I am not familiar with. 
All input will be greatly appreciated.

Be Safe,
Emil

@edcyn, good descriptions and recommendations.
Something I've noticed, DG somehow managed to make Abbado's recordings sound good...thankfully.

What, no EMI and HMV? These were the favorite labels of HP (Harry Pearson), founder of TAS!
Naxos is v good and often overlooked. I’ll buy almost anything on the label and haven’t been disappointed. 
Fwiw I think DG is overrated. Great musicians but sound to me is disappointing.
