Congrats on the RP1 and taking the plunge into vinyl. Its a lot of fun. Your also trying to build your system backwards.
Here are my thoughts.
1. I have found that external phono stages are often much better than the built-in ones found on integrated amps in the price range that the Brio is in. However, since every component should be carefully selected to compliment one another to achieve a balanced system, a great phono stage like the Jolida may be held back if the rest of the components are not up to its level.
2 & 3. Forget about matching the Jolida to an integrated amp. An amp should be chosen on its ability to drive the speakers that you have. This is its primary purpose. The rest, such as what components you plug into it, is secondary.
So, its important to always choose the speakers first and build the system around them. They will have the biggest impact on how your system sounds.
The above being said, here is what I suggest. You already have the table and I assume you plan on using it with the stock Rega Carbon cartridge that it comes with. If so, forget about the Jolida - it is way too much preamp for this class of cartridge. You can use the MM built-in phono stage on the Brio or any other integrated you happen to buy providing...
That you go out and audition the speakers first! Once you find speakers that sound best to you, then check to see if the Brio is a good match for those speakers and will properly drive them. If it can, no problem as you already know its phono stage is a good match for your TT/Cartridge combo. If you have to select another integrated that may do a better job driving the speakers you fell in love with, thats OK too. There are many more out there around the price of a Brio with good MM phono sections.
Good luck Corin!
