A lot of DIY'er's have performed the Hazen Grid mod on their non Decware amps and this usually skeptical crowd seems to appreciate it as a viable mod as many seem to claim that it does in fact make an improvement. If you do some Google searches on the subject, you'll see lots of discussions.
Now that said, even if it does improve the EL34 triode sound, I would still go after a well built 300B if it was in my budget.
