Idagio and Primephonic

First of all, I have only used Primephonic. 
In terms of audio quality, while most of Primephonic’s 3.5 million recordings are 16 bit/48 kHz, there are many that are 24/96 and some that are 24/192. Of course a new 21st century recording is more likely to be 24/192 than a remaster of a recording from the 1960s. 
Probably the best part of Primephonic is that they are constantly improving their service. They are expanding their catalogue on a daily basis, and they regularly update their apps. 

Thanks for your input.  I may try both for a while--Idagio has some nice exclusives (with the VPO, for example) that may make it worthwhile.  Both seem like excellent sites, from the limited time I have had with them.

@rcprince No problem! I would be interested to hear your thoughts between the two.

Basically they both are classical streaming services with CD quality and certain unique “upgrades”. I.e., Primephonic has a large selection of Hi-Rez and claims to have the largest classical catalogue, but I’m sure that Idagio has benefits that I don’t know about.             
My (first) 12-month subscription to Primephonic is ending in ~2 months, so I’m trying to decide if I will renew it or not. I have been impressed with their service, but I may also check out some free trials before I renew.

I will let you know.  Right now in the trial period I like them both, Primephonic for the large catalog and hi-rez capability and Idagio for their exclusive recordings from the VPO and other orchestras.  Both are easy to use and very helpful when you contact them.
