Hi, i'm not actually after more watts, and as we know the Tubelab SSP is a suitable 25W amp.If you can get the SOVTEK EL84M, go for it, it seems to be a modern build of the 6P14P-EV, which is famous for durability and quality.
Is the EL84M a direct equivalent? It does say on this link, that the EL84M's - 'Sovtek EL84M lifetime is estimated to be 5000 hours versus 3000 hours for a standard Sovtek EL84.'

I don't plan to alter any bias on any of the valves. I just want a 'straight forward build' switch on and enjoy 'valve' sound.
I would imagine that the Tubelab design runs the valves within their comfort zone and are not pushed hard.
