Agree with @josephting opinion. The weakest point of your headfi system now, is the dac and amp.
e09k and e17 is very good in that price range, but they still not good enough to release the potential of your PS1000.
I think your set up now will sound a little bit thin, the outline of the sound is not warm and solid enough.
If your budget is up to RM1000, can keep your e17 as a dac, and upgrade for a better amp.

Digital cable definitely makes different, especially in hi-end set up.
But for entry level equipment less than 1k, I won't suggest the user to buy an usb cable more than RM300.
For me, Belkin gold usb (this one won 2013 TAS EDITORS' CHOICE AWARDS http://www.theabsolutesound.com/articles/2...interconnects/) or Amazon Basic usb which only around RM50 is already good enough. haha.

Do you have any rca cable? If not, I'll suggest you to get a good rca cable first after upgrade your dac and amp.

I see. It's better to get a dac first. Burn in the new set up for around 200 hours.
When the sound become stable, try to find out the weak point and buy a usb cable that can improve your system.

ps. Sound signature of PS1000 and Solo Diamond both are slightly bright and active. I think you should get a thicker and warmer dac and balance the sound signature.

Sure, it's difficult to choose. Reviews won't sing for you~ haha
It's easier to make a decision if you have a chance to try them before.
Anyway, what's your budget for DAC and RCA cables?

I'll suggest you use all budget to buy a dac first. haha. You can get a very top dac around 4k~5k.
There are many many many many......good dac within this price range.
Cambridge is good below RM2000, but it's not competitive around 2k~4k.

cables are important, but it should be the last part to upgrade in the whole system.

As a seller, I'll be very happy if customer buy whole set of equipment. hehe

But as a headfier, I'll suggest you to upgrade step by step. Get your amp first, burn in for 200 hours, find out the weak point that need to be improved, and find a dac which can solve this problem.

I've seen too many headfiers buy headphone + amp + dac + cable in the same time, and sold out all of them after few weeks or few months because they dun like the sound signature of that combination.
Mix and match are very important in the world of hifi/headfi. Best or most expensive + best or most expensive equipment might not equal to BEST SOUND. That's why I always suggest people buying things step by step, especially hi-end products.
