Definately.... I still use my TP60 when I fancy a change from my HP-8 with my HE-6. For the price it is an astounding amp. It can't compete with the HP-8 in true terms but it does make me smile when listening via the TP60 because it's not a million miles away but costs five times less. There's something nice about knowing you have a quality piece of kit punching above it's price point.
I've used the HE-6 balanced with the PB2 to good effect but the TP60 just makes them sing. Expect a bigger, fuller sound with improved dynamics and extension. It needs a decent input, rubbish in = rubbish out.
