Turntable

would this cable be okay as well?

Yes, that will be fine.

There are some other budget TTs that aren't digital but have a built in phono stage, but another one similar to the Project digital that you may want to research is the one by Flexson UK, made by Rega. Flexson markets it as made for Sonos, but that isn't a unique thing, the digital Project would work with Sonos just as well. I think that Flexson includes RCA cables in the box though. See:

You need to see if the RCA cables are terminated at the Sonos end based on what Sonos product you will connect it to - the play 5 will need a multijack for its single line in socket, Connect/Connect Amp have a jack each for left and right. Other than ensuring this, any RCA connector cable will do.

No phono stage? Are you sure?

Built-in phono pre-amplifier with analogue & digital out Gold-plated RCA interconnect cable included

EDIT: Apparently the Amazon listing is incorrect. The user's manual states there is no pre-amp, only a phono output. So you will need to purchase a phono pre-amp with the Essential II Digital.

That seems unlikely:

Henley are the UK distributor for Project and they know their stuff, the digital DOES include a phono stage. It would be nonsensical to have an optical output at phono level and it would be equally as absurd to include a phono stage for the digital output but not the analogue output.

I'm just quoting the users manual:

If your amplifier does not have an input suitable for phono cartridges you will require a separate phono amplifier stage for MM or MC cartridges which is then connected between the record player and a free line level input of the amplifier.

Well, the what hi-fi review suggests it does have the phono stage as well and you'd hope they'd actually tested it. I can imagine most of the digital's manual was copied from the basic essential 2, perhaps it wasn't sufficiently well proofread?

Looking at it, I'm not even sure that is the Digital manual in the link, though it was right there on the Digital's info page. I'm thoroughly confused.

I don't know which manual you guys are looking at; the link takes me to links to product specs and a manual for the digital TT that does say that a phone preamp is built in, and line level outputs provided that are NOT suitable for phono sockets. In other words, these ARE suitable for standard line in sockets such as those on the Sonos kit. There are links within the provided link to get to those pages.

As seems logical too.

I think the OP could be equally ok with it as with the Flexson. The latter includes both kinds of RCA cables in the box. I had a Rega P5, the Flexson is a P1 but I think it is just as easy to set up for the balancing and anti skate. Reviews say that the Project is a little fiddly on this count. A nice comment was from someone that says he took 30 minutes to set up the Project - 5 to set it up and 25 wondering/worrying whether he had done it right!

Hi all, will this connect to my play 5 ?http://www.pioneerdj.com/en/news/2016/plx-500-direct-drive-turntable-for-djs/

Already answered this.

Answer yes can feed into Play5 - there will be a 70ms delay of the input to Play:5 and the output on your Sonos speakers throughout house.
