Ok back to the matters at hand - or the the things that matter.
Finally finished my LT3042/R-Core DIY LPS project last night and gave it a listen:
This runs at 5VDC only - not adjustable.
So I took out the TeraDak DC30W (modded HW caps)/DC iPur/Recovery and ran the DIYLT3042LPS straight into the iPur2>F-1. This is easy with the 2G split cable. Just needed a 2.1mmDC Female to USB A Female adapter which I have. Plug in the power leg of the 2G.
So how did it sound - without burn in time - excellent! Very, very smooth and musical. I did notice a lower level of dynamics, or vibrancy. This uber vibrancy is one of the great traits of the
'Ultra' USB chain. So I tried adding the DC iPur - that sounded worse. I will burn in this unit for 100 hrs and give it another listen.
On returning the DC30W/DC iPur/Recovery - and the vibrancy and jump returned - but with no noticeable loss in warmth or musicality. Tried the DC30W without the DC iPur and it was barely noticeable. Just a hair better with it in.
Now the second experiment last night was using this DIY LT3042 LPS to power the PC PNY CS2211 SSD running the OS. This cable finally arrived SATA power to USB:
$10 https://www.moddiy.com/products/USB-to-2.5-SSD-5%252dPin-SATA-Power-Adapter-Cable-%2820cm%29.html
So now running the SSD with the OS from the LT3042 LPS - I noticed a bit better SQ. Just a bit more air and depth to the sound stage. Well worth the money.
So I tried then using the second free DC power port on the TeraDak X1/X2 (moded with HW caps)I was using to feed the LEX. The sound remained the same - with that slight improvement. Note the DC power port is adjustable - so I set it to 5VDC which the SSD needs.
So I don't think an extra LPS is needed for this duty - the X1 can fill both needs.
Cheers
