Upgrading a Croft 7 Power Amp to a 7R - How does this help?
I am currently enjoying listening to a pair of Magnepan MG-1 loudspeakers - within their limitations in my sitting room. I say within their limitations because I understand that 'Maggies' really need a lot of power and control (similar to Electrostatics) to really make Maggie sing. So I am intrigued at the potential left in this design.
I really like my current Croft 7 pre/power combo - so my dilemma is that I like the panel sound I am getting from these Magneplanars - but I don't want to ditch the Croft in favour of a more powerful amp with greater drive.
However, it would seem that by upgrading Croft's power amp to an R - which adds a (valve?) Regulated power supply - this will greatly improve the Croft's ability to deal with the varying impedance fluctuations of panel speakers like these (and Electrostatics if I choose to try those later too).
If 'R' only adds Regulation and not more power (so 45 Watts now and 45 Watts after upgrading to the 7R) how is this so? And how does that work electrically speaking where Regulation help control difficult loads despite not altering the Wattage of the amp?
Thanks.
