You probably cannot do better than a 12V SBooster. That being said there are many less expensive 12V LPS units available through eBay and elsewhere. A search on the forums will get you a list of those that have been used with success. As for "consistent with the cost of the 2qute" a good power supply might elevate it, or any comparable unit, considerably. See what LPSs people are using with the Brooklyn DAC, for ex.
Given what Chord says though about using anything other than its own wall wart, might you have to clear a choice with Chord in advance to avoid ruining the warranty? That seems pretty odd.
