Any need for Phono stage with Brio

The first question is how does your vinyl playback sound to you now? Are you finding flaws in the performance?

Second, will a stand alone phono preamp sound better than the built-in phonostage in the Brio? The answer is yes and no.
If you purchase an entry-level phono preamp or a mid level Rega, there would not be a significant increase in SQ. It’s a horizontal move.
For a significant upgrade, you would need to move up to the next level of sonic performance and build quality. Perhaps a tube phonostage would be in order.

With regard to your cartridge, you can do a lot better than the Elys. My advice is to upgrade to an external phono preamp when you're ready, but audition a couple at a retailer or purchase with a 30 day trial period.
Once you’re pleased with the phonostage, a cartridge upgrade should be next.

Many thanks for the replies, it has come about since reading some reviews etc and got me thinking about this when a Arcam rPhono was used with the Brio.

I am happy with the sound and enjoy what is played, vinyl sounds lovely and had listened to the Brio and Planar 3 with the Elys 2, I was a little skeptical with it after hearing what people had to say but for me (listening from Planar 1 upwards) this had a good sound as a whole.

The cart might be something that I upgrade but I have been looking at speakers recently also which will need to be in white as there appears to be more of a range these days compared to when I purchased mine.

Since you're pleased with your current system, your phonostage is fine. I agree with @viridian that a new  cartridge will be the most dramatic upgrade.

@viridian and @lowrider57 which one would you recommend I look at when the time comes?
