Is it worth upgrading from a Topping DX3 Pro to a Topping DX3 Pro+?

[charlesd11]

Hello, this is my first post here and wanted to ask how much of an improvement is the DX3 Pro+ over the regular DX3 Pro. I've been having this DAC/Amp for about 4 years and it works fine, but I wouldn't mind upgrading to the Pro+. If the upgrade isn't really too much, is there any other DAC/Amp for about the same price that would be a good upgrade? I listen mostly to classical and opera with my DT 880 Pro (250 Ohms), so the neutrality of the Topping amps works very well with what I want.

EDIT: I also plan on buying the Edition XS and the K702. If that matters.

It wouldn't be a night and day difference since you have high ohm headphones. A practical way for better sound would be use yours as DAC and the Topping L30 II will sound better. The Topping E30 II is the matching DAC for a good look if you sell the DX3. Otherwise RCA cables will let you plug right into it as is.
The L30 II sounds as good as the much more expensive amplifier I've got, and the noise floor is so silent sensitive IEMs are amazing if you get into those.
