The Arro is a great speaker choice for under $1K.
Listen to your Arro first and be patient. It will take a while to break them in (common issue with Totem and Dynaudio speakers) before they could sound their best. See if you are content with the sound that your current amp, CDP, and the Arro produce. If you are, do not waste your money to upgrade your electronics until the PS integrated breaks down which I don't think that will not happen any time soon.
Totem has recommended Rega integrated and Rega Apollo with the Arro, a very popular combo in Europe. But of course, Naim 5I and Naim CDP will be significantly better than the Rega combo.
You would have to spend 2 or 3 times more if you want a better CDP than your current Music Hall. The local Totem and Dynaudio dealers in my area have recommended the Music Hall if your budget for a CDP is around $600.
Better interconnect say Monster or AudioQuest helps but do not spend more than $70 per pair. That was my Totem dealer's recommendation.
On the other hand, the speaker cable upgrade is worth the $$ but do not go over the $1K mark. Unless, you can print money faster than you can spend.
Enjoy.
