Budget was blown apart when buying the us4 and susvara.
i believe the us4 and 4+ both have preamps (or work in the same way) don’t they? Correct me if I’m wrong

From the Power Holdings webpage:
The US5 Pro adds an additional balanced headphone connection. Since the 4.4mm Pentaconn connector has gained popularity as a new balanced headphone connection standard we have decided to add this feature and renamed the the product the US5 Pro. All other features and specs remain the same as the US4+.
The US5 also adds the 4.4mm Pentaconn connector along with every other feature from the + plus model except for the relay volume option. We have found the US4 was not very popular and most customers wanted to simply choose between a standard Alps potentiometer or the relay volume option without sacrificing any of the other features.

Okay, let the pre-owned US4 and US4+ models start showing up on the used market... the more generously discounted, the better... 
All hail the gods of planned obsolescence !!

I don't even get my US4+ and US5 is coming up? LOL
At least it's only difference is 4,4mm connection.

I doubt that will be the only differences.

seems to me those who bought the 4 and 4+ should be allowed to trade them in for the replacements

I was a fan of V200 and V100 and was tempted by the US4.... by looking at the prices of the US5.... ZERO chance I would buy one... and I guess not many US4 will be on the used market.... oh well. Might try a V550.
That will be great thing... But not in this world...
US4 is not a cheap AMP so...
Aside from getting rid of the US4, which I never quite understood as a product,
this seems like a frivolous upgrade to me. But what do I know! I’ve seen next to no demand for the pentaconn output on this forum but it must be coming from somewhere. Fried mentioned to me at CanJam last year that the V590 was built partially in response to demands from the Asian market for all-in-one amp/dacs, so that might be behind this change as well. I would’ve liked to see them add another balanced input à la the SPL Phonitor amps but oh well. Anyway I’m feeling zero audio nervosa about the US5, and I must say that was the whole point of getting the US4+—not worrying anymore about what else is out there that might be better!
