As others have said a little battery conditioner and a small SLA battery in a box work very well. I ran a Sonic Impact on similar a few years back, it was great. These things don't have to be bulky or ugly.
Very well I'm sure, 45-50 amps is HUGE. The SMPS I've seen are 5A max.
I can understand how you think that but there are cases where a well designed smps can improve on a fairly decent linear ps. Only today have I come across an smps which rivals an SLA and knocks a Muse/Ordo linear ps into the weeds.However, the cheapest linear bench/CB radio supply will be much cleaner than the best switch-mode: Tripath love them. Voltcraft are the best of the bunch, I think: we've published one or two articles about how to mod them.
It's from Temple Audio, 18V 2.7A. The Ordo is 5A and can reach 16.4V or my example can anyway. I've been auditioning several alternatives and have been surprised by what I've found, which I have to say is not entirely predicable.Tell us some more then, Clive. What model and output voltage is it?
Agreed, the technology will go to those currents, but what I'm getting at is the size of the circuitry required to deliver 50A. A sustained 50A, too. IIRC 2.5mm T&E is safe to 30A, so you'd need double that. To run a T amp too. I agree a linear PSU will be huge also, though.Have a look at any PC power supply. They are not huge. They are all SMPSs, and power outputs of 800 W and more are not unusual. The outputs are a mix of 12V, 5V and 3.3v, so currents are well in excess of 50 A. Try to imagine that as a linear power supply - *that* would be huge. There is a reason high-current supplies tend to be SMPSs, not linear.

Is this suitable for the Bantam Gold or is it for the monoblocks . Do you have a link for this PSU Clive.
Thanks Clive . I think I read somewhere that the Gold will accept 18V . One of my mates has the monoblocks with the latest PSUs . I'll see if I can borrow one and test it ( using my Bantam Gold ) against the 12V SLA battery which I currently use . I'll post back here if I manage to do the comparison.
