Well, I’ve emailed Richard to send the Melco S100 back.
I’m quite frankly astonished than anyone could find it to equal a “naked” EtherRegen never mind one with an external reference clock like the SoTM or Mutec.
There’s no doubting the Melco has a very unfatiguing, rich sound with a low noise floor, wide soundstage and “pop-out” separation. The latter is quite impressive on some music but however entirely unnatural and can have strange effects on acoustic instruments, spraying pianos, guitars and drum kit across the sound stage.
The biggest and most unpalatable defect of the Melco for me, however, is that it smears and dulls the tones and textures of classical instruments.
Some people may find piano treble or violin a little harsher without a switch or with the Cisco or EtherRegen, but that is what they sound like, and losing this loses a considerable degree of expressiveness. Everyone who was tortured with blind testing agreed with this, though using their own terms, which included, dull, flat and closed off amongst other adjectives. There was also a full consensus that the S100 was less involving than the EtherRegen.
If you mainly listen to rock and electronica you may find this less of a problem, depending on whether or not you are also a PRaT fanatic. Everything is softened and mellowed on the Melco. It definitely wasn’t for me, and after near on 150 hours burn-in from new I was very happy to get it out of the system.
Adding an external power supply does lift things in most areas, but not massively and certainly not anywhere near enough where fidelity of classical instrument replay was concerned.
There is no doubt in my mind that this switch was designed with a particular sort of sound in mind rather than to get rid of ground plane interference/jitter/phase noice etc., and it’s definitely not a sound I’m looking for. It has put me even more off Melco, overall, and confirmed my impression that certain types of high-end gear pursue very different priorities to my own.
This was all in a system consisting of Roon Nucleus+ with internal Samsung pro SSD drive and Sean Jacobs DC3+ LPS, ND555 with 2x555DS PS, Naim NAC 552, Naim NAP 500 and Shahinian Diapason speakers. I use two Sean Jacobs Powerblack mains distribution blocks, which outperformed my old Powerigel.
Your mileage may of course vary with other equipment.
Where the new English Electric fits in with all this I have no idea, never having heard one.
Instrumental tone and texture are superior in my system with no switch than with the Melco. I think it loses some of this as a trade-off for a very low noise floor. The S100 sounds like it works as a filter.
I certainly wouldn’t recommend that anyone get a Melco S100 without an audition or sale or return home trial. I’d also recommend that you do the same if you are thinking of a linear power supply for one. I did not find it made nearly as big a difference as adding one to the EtherRegen for example (or Roon Nucleus for that matter). Possibly the stock SMPS has been improved since the early models or something else has happened. The SMPS certainly doesn’t look that impressive. But then, the S100 has a low current draw (12V 1A).
I’m a little sad to be so negative, but although having a quite nice sensuous lower midrange/upper bass hump, I found this a very disappointing product for the aspects that most matter to me: acoustic instrument fidelity and PRaT.
I would certainly recommend a PD Cisco with bundled external power supply over the Melco at a tenth of the price and very definitely the EtherRegen at less than half the price. I find the EtherRegen immeasurably more satisfying musically and so did everyone who heard both it and Melco in my system.
