Hey All,

I have recently discovered that changing the discreet op amps inside amplifiers can have a huge effect on the sound coming out, I have an XDUOO XD05 BAL and have changed the op-amps to a pair of SPARKOS LABS SS2590.

I am looking for a full-sized balanced headphone amplifier, that has XLR input and of course, has interchangeable op-amps. Something like the Burson Soloist 3X would be perfect if it was a little cheaper.

Thanks for any and all suggestions in advance!

The cheapest fully-balanced amp with swappable op-amps that is currently in production is this Gustard H20:

However, the Matrix Audio HP-3B, which was discontinued as the 2020 global pandemic took over, is still apparently available around your location:

Wow the Matrix Audio HP-3B seems to be exactly what I'm looking for, thank you soooo much!!!

The Gustard H20 looks good but is similarly priced to the burson

If the Matrix Audio HPA-3B (missed the "A" because this model has been discontinued for a while) is indeed in stock, then I highly suggest that you tell friends and family to buy one for their own, as these are apparently amongst the last brand new inventory in stock anywhere on at least Google's search engine.

Oww I bought the Matrix Audio HP-3B, but they had sold the last one on Tuesday, I think I may just buy another XDUOO XD05 BAL sa for the price it is fantastic with the SS2590
Actually working on a 3d pritned enclosure to keep it all neatly contained, which will be alot better than this mushroom
