My final destination was 2 psu's for the 282. Better drive and clarity over the 1.
I basically use an old HC and a TC.
I can understand though, why non Naimees think we're mad.
Including the napsc there are now 3 power supplies just for the preamp. And they're best left on all the time.
It's a bit bonkers!
So you are on a combined Naim and Teddycap PSUs on the 282, just like what I did previously. That's just great.
Your used to a more controlled sound by running a teddy cap anyway, so getting a dual one will be more of the same, you'll know what to expect. And as others have stated, moving it on wouldn't be a problem.
I had a 282 for 9 years and always ran a dual teddy cap on it. Loved it's bottom end, it was so much tighter than a Naim psu but you do lose that "Naim drive".
I like Witch hats idea, that would be very interesting to hear what that combination could do.
A general pattern on the characteristics of both Naim Hicap and Teddycap can be understood with all the terms that are used to describe the sound. It is useful that you find the Dual Teddycap to have a more controlled sound and tighter bass than a Naim PSU, presumably the Hicap 2 or DR. That was my experience as well. Sometimes it is difficult to translate all these words into the things that we hear in real life experience, vice versa.
The Dual Teddycap has a more controlled and tighter sound than the Naim Hicap as all the decay(looseness) is cut short. As a result, the sound is cleaner, more controlled and tighter not only in the bass but the midrange. On the other hand, the Naim Hicap sounds looser and less clean, but due to this looseness it has a livelier feel, a more live sound. Coupled by the mid-bass bump, this gives music the drive.
A "better" sound (or better PSU) will be dependent on what sort of presentation one is after, a clean and controlled sound of the Teddycap or a looser, less controlled and livelier sound of the Hicap. This goes the same with one or two outputs connected to the 282. The closest analogy I can think of that relates to the comparison between the Teddycap and Hicap is the comparison between the Harbeth Monitor and Domestic series of loudspeakers. Specifically the Harbeth M30 / M30.1 / M30.2 vs Compact 7ES3 and Super HL5 Plus or non-Plus. The Teddycap is the M30 / M30.1 whilst the Naim Hicap is the Compact 7ES3 / SHL5.
OF course, cost can be an issue and I surely support the notion of the great VFM of the Teddycap units which appear to render the Naim PSU (especially the Supercap DR) to be of poor value. Having said that, I also understand that the perception of "value" is quite subjective and there are some who view the 282/Supercap DR to be of great value sound for pound.
