I haven't heard either one but I will compare them at CJ against the T2DIY. I do know the circuits well and for my money there isn't a bad choice to be made here. The BHSE will be more linear since that was the whole point of the T2/BH design plus it is DC coupled so there are no caps in the signal path. The WES is a traditional tube amplifier so it has input/output capacitors plus the stages are all AC-coupled which will give it a warmer tone. Since it is an old school tube amp it will also not have the total immunity to the load present which the BH has going by my experience with the ESX it shouldn't be a big deal.
Bottom line is, what sound are you looking for?

on this forum, an amp very much in the same category.
The only thing I could find was a thread about the original Coriolan which was twice the price.
The Coriolan 2 is for us Europeans the same price as the BHSE or WES if you count import duties, probably even cheaper.
This amp has nothing in common with either the BHSE or WES in terms of performance, just because it costs about the same doesn't mean it isn't an overprice piece of crap (which it is). The Coriolan is just the same old Egmont circuit with parallel output tubes and an abysmal PSU design. This circuit is ancient (1950 or even older) and about as simple as you can make a dual differential amplifier. It also doesn't have anywhere near the power needed to push the modern phones or low enough distortion. On top of that you have the typical Rudistor build quality which simply horrible and couple that with a bias supply which will destroy your phones and you are on to a real winner.
I've now built three versions of this circuit and the only one which was passable used far better output tubes and much higher operating voltages. I also incorporated feedback and other changes to make it anywhere near linear. I also have a PCB design ready where literally anybody can build one of these amps for a lot less then an Exstata.
