I think Heed are overpriced for what you get, the power supply is poor to upgrade you need to pay about £700, they do seem to have some build relibilty issues as well, I would steer well clear, if you want to upgrade I would look at some used amps, which seem to be going fairly cheap at the moment.
No, no - said many times it would take some amp to replace the Leema, but as the Pulse is a few years old just wondered how these new kids on the block compare to the slightly more mature amps.
Thanks to this forum that you sometimes have to ask these (non-essential) questions.
