It’s a choke and it’s done that way primarily for efficiency. In that version, with a pretty high current operating point, you need a lot of those expensive 2W resistors at £50 a pop vs doing it with the choke, plus the voltages are easier to arrange. Could be used a transformer as you suggest, but I don’t see any real advantage, and possibly a disadvantage in terms of bandwidth. You could also use a CCS.
With Kevin’s, (a) the resistors are cheaper and (b) I chose a different operating point, which gives a more characterful sound and, happily, allows the resistor dissipation to be reduced.
The built in phono is remarkably good in the pre. You get an mc4 sut , nearly an 88pb phono stage minus one input, a pre scaled down from the 912 - £2800?
One more stand for the HD600
RME and G109-S on the tops shelf
2nd shelf currently has the Topping D10 doing SPDIF conversion from a HP Chromebook and SPDIF output, coax to Chord Mojo, Optical to RME (which also has USB input direct). Makes it easy to direcy and quick comparisons in my more geeky moments.
Chord mojo to the XDUOO MT-602 which has had Mullard tubes put in place of the stock tubes and using the Ifi Ipower PSU
Topping D50S not being used at the moment, same as the SABAJ PH3
Saving up for something else, just to have something to save up for but not sure where else I can/want to go with now - The Orbe, on the bottom shelf, really needs a service and an oil/belt change if I ever get the proper time to do it.
The Topping DX3 PRO + P50 now being used downstairs for when The wife is watching her stuff on TV.
