There is a 2-channel version, the CS3308 IIRC. It may have a lot of pins, but performance wise it does run rings around anything else.
And it has SPI 😉
Edit: Its the CS3310. 16 pin SOIC.

The CS3318 only comes in 48-LQFP. The CS3310 is basically the same thing as the PGA2311.
You can buy 2x PGA2310 DIP on fleabay for $10.
The PGA2320 I have would cost you nothing more than shipping. Surface mount is not hard if you can make your own boards. If you do everything p2p then that makes it a bit more difficult.

I would love to get into making my own boards. However where would I get the designs from? I looked at Altium Designer, but not sure when ill have the time to learn as it looks pritty complicated! atm I use veroboards.
I looked at ebay, but all that I could find was a PGA2320 (surface mount) or PGA2310 (DIP) which I am interested in, however not sure if I will be able to get more than the two he is offering, but eventually I will build a few volume controls (around 4 pairs) and would like to use the same chip.
Any suggestions?
Thanks

I think I am running out of options, so shall go for the PGA2310 from ebay. Thanks for everyones help and advice.
Can someone please explain what the 5v digital is? I can build a power supply for the +/- 15v, but not sure where I get 5v digital from!?
Thanks heaps!

Ive come up with one last idea, and after some suggestions as to how logical it is!
I was looking at the LM1036 which is a volume controller with bass, treble and balance controllers. Data sheet
I am wondering if it is possible to use a Digital Potentiometer to replace the 47K variable resistor used for the volume control? (the variable resistors for the bass and treble can just be normal pots as i wont need to control them digitally.)
If this is possible, I am wondering if I should use a 45K or 50K digital pot?
An example of the pot is here
Any suggestions would be much appreciated!
Thanks guys

5V digital simply means a 5V supply that is *only* used to power digital circuitry. The reason for the seperation is to avoid digital noise getting into the analogue part of the circuit.
So it's as simple as building a 5V supply that you will only use on digital circuitry 🙂
Or just put a 5V regulator on the +15V supply. This is how the 5V supply is aquired on the mini volume control board I have and there isn't any noise problems.
