Plixir Elite BDC MK2 linear power supply – Single and Dual – 5 Volts

Intro

Power – or energy – is everything. We’ve been saying that for years. Clean, stable energy is the basis of any good system. If the power supply is not good, a system can never sound good. We are testing the new Plixir Elite BDC MK2. Both the single and dual versions.

Plixir is by now a stable presence when it comes to power supplies and power conditioners. The manufacturer – James Soh – is based in Singapore. Everything is also handmade there.

The Plixir Elite BDC MKII is the successor to the – quite surprisingly – MKI. According to Plixir, the MKII inherited some things from the Statement. Think a better pcb design, more capacity on the output, and the Star Ground plane design which we also discussed in the review of the Statement.

The basis is a balanced transformer. This balanced transformer already suppresses a lot of noise of its own. Of course, the 230 volts must be reduced to – in this case – 5 volts. This is done in two steps; an open loop (pre-regulation) with a filter and then a closed feedback loop.

In the end, this setup – with the improvements for the MK II – should make the noise on dc output even lower compared to the MKI. And that in itself was not bad! Plixir is now talking about less than 1mVrms, which is extremely low.

The casing has remained the same. In any case, pun intended, we see no real difference. But we don’t have to, because it’s a nice, sturdy, well-finished product. This is definitely built to last. And considering the price of 749 Euros (single, 3A) or 999 Euros (dual, 5A), we think it’s also a long-term investment.
