Hi @Jaybar
Read this post by @Homeworks
I have a 333 and in NYC area. I could help you with a comparison if youāre interested.

Thanks Have you ever compared? More importantly, have you ever used the default Naim cables to connect the 332 with a NC amp?
I have. I used to own an NDX2 with XPSDR. The 333 is more technically capable, it does extract more detail than the NDX2. I have however found that the PSes add a fluidity and organic nature to the sound that I personally miss with any of the 2 streamers naked. I would not choose the 333 naked over an NDX2 with a (serviced and well performing) PS. It really depends on what youāre looking for, the 333 will give you more detail and potentially more soundstage width but without the PS I find it less engaging.
Cables are a different story, the stock ones are perfectly adequate and you can get improvements with more investment there but I would not consider those a day 1 purchase.

PS really make a difference with streaming. 222/555PSDR outperforms all the OC streaming for me sans the ND555.
Iām not clear about what you mean. Can you restate?
That may be true.. Personally, Iād prefer the ndx2/555dr over the 222/555dr as my sourceā¦ Which only goes to show each to their ownā¦

Iāve stated this many times here. The 222 utilizes both outputs of the 555 unlike the 272, NDX2, etc, which allows the combo to punch way above itās weight. I spent a lot of time with the NDX2 in various systems and wanted to buy it but for me at the time it didnāt warrant the higher price even with the XPS. Itās just okay. Itās a fairly resolving player but just not as musical as the NC which is much more full and realistic sounding. The 555 made it better but the 222/555 is still better to my ears. And with the 250NC the 222/555 are tough to beat. Maybe the NDX2 will sound more musical with the NC amplification. I havenāt tried that combo.

The 555psu is still a stupidly expensive PSU at Ā£8k in the UK. But secondhand, serviced (at Class A), for a smidge over Ā£3k secondhand, itās a no-brainer over the XPSDR, no matter where it is usedāNDX2 or NC. And it is one of the few items that can move from classic to NC setups. I always like to look inside the box (as well as listen with my ears). Look inside a 555DR and compare it with the NC PSU.

The P9 powers supply is full width. The Rega phono is about 8.5 inches. Wonāt fit.

Does the Naim series 300 phono stage include a cable in the box?
It includes a power supply cable. As mentioned above the NAC332 has a DIN connection that handles signal + power for the NVC TT.
8-pin DIN has +/-18V (for compatible external phono stages e.g. NVC TT)
So if I wanted to connect it without using a power supply, what do I need? Thinking of purchasing the phono stage.
The 8 pin din cable is supplied in the box. Itās all in the manual ā¦. That will power it from a 332 for example.
Note Bene you cannot use it with your current system without also buying the compatible power supply.
Can it run without an external power supply by using the PS cable?
No, not with what you have now.
It can be powered by;
preamplifiers NAC 332 or NSC 222
NPX TT
Thatās a lot of Ā£$ for a source that youāve stated doesnāt get that much use.
If you want a separate phono stage, get the rega aria.
Honestly, this jump to Naim new classic; youāre contemplating replacing everything that youāve only bought in the last, what, 18 months?
Thereās absolutely nothing wrong with what you have right now, youāre chasing the elusive 5% gain thatās going to cost multi thousand dollars.

I will be purchasing the 332 and nap250. The jury is still out about the 333. The dealer says I should keep my NDX2/SPXDr. In that context does the Naim phono make sense? Also how are the supplied Naim cables to connect the 332 to the 250? My dealer is recommending Chord Sarum T or the Signature. .

Dealers make a much bigger mark up on cables so always recommend them. I wouldnāt change them initially. Save it for later when you get a feeling to add a little bit more and spend some more cash.

Looking at the OPās original post, Iām puzzled by all the responses suggesting the 300 Series, etc., etc. would be a better choice - of course it (possibly) would be, itās a lot more expensive!
But to answer the original questions;
Can I control it with the Naim app on my phone ? - YES
Do I need the system automation cable? - Not necessarily, but it is supplied with the NAP 250.
Can I control the volume? - YES, either with the Naim App, or the large knob on the front of the NSC 222.
Can I start without the power supply? - OF COURSE.
I am assuming the amp can drive my Spendor D7.2. - YES
āI am aware that streaming may not be as good as my NDX2 although the responses are mixed on the forum.ā - You are quite correct, responses are very mixed, depends on whether you like OC or NC. Not having owned the NDX2 I canāt really comment, but I have been delighted with my NSC 222/NPX 300/NAP 250 - YMMV 
.
As well as the System Automation cable, the necessary XLR interconnect and mains cables are also supplied, so Iād start there before moving to more exotic options.
And, of course, if you can up your budget to a 333, 332, 2x300, 2x350, Iām pretty sure youād be delighted too.
