Switching back from an LPS to a decent SMPS for my switch.
1 Like
This is an argument that intrigues me recently.
Iâm using a PSU from Sean Jacobs to feed a (non-audiophile) router, I was thinking about it as the best solution possible.
I suppose you watched on YT what Yaap from Alpha Audio discovered about the beneficial effects of SMPS vs LPS (speed etc etc). Also Hans B confirmed the Yaapâs theory, if Iâm not wrong.
Recently Network Acoustics (Muon Pro designers) launched a switch called Tempus, that comes with its own âhybridâ supply, a new SMPS based on filtered stages. I was told that they will soon launch a similar power supplier for general routers.
I want to give it a try.

The trend seems to indicate the newer SMPS is as good as LPS, or even better.
I use a simple iFi PS for the mesh satellite, and connect it to P15. I was pleasantly surprised to hear the improvement. My main router is upstairs with a regular PS, and I wonder if an audiophile PS will do anything since itâs WiFi to my satellite.

I put those $100 iFi Power-X bricks on my incoming modem, main router, and mesh routers. Although it is impossible to A-B this I feel positive that there is an improvement.
I dont remember if I put one on my main Netgear switch or if it was 120 VAC only.

Yes I was referring to that video.
As for Tempus you can find something here (no tech details, though):

I thought I could see some pictures of your speakers. Hope you already have it and you like what you hear.

Here are pictures of new vs. old. The reason that I did not post the picture sooner is because I am waiting for a replacement of the left baffle mid-cover. The one came with it was a bit too long to fit. I should get it soon, so I plan to post it later. But since you asked, here you go.
I will post my initial review tomorrow too to give them more time to break in.
So far, I am super happy about the SQ

Donald looks great and it certainly sounds good in the room. A beautiful high ceiling with cozy slants. Nice and airy. The speakers donât seem that big. The new speakers appear very delicate, like an iPhone. Do you already have other feet? These look like finite elements in the picture. Now that you have the speakers in place and can hear them, you can also think better about whether you need other feet and if so, which ones. Have fun with your new sound experience.

I am lucky the high ceiling totally eliminated any top reflection. I do not need many sound absorbing panels either to have good sound. The room is over 33â long (14â high at the highest point) so the big speakers can really sing.
The aftermarket footers make a significant difference especially on bass and soundstage. I will talk more tomorrow on how good FR30 is.

Looks great Donald!! Love the white contemporary looks. I wouldnât bother with the baffle covers though, grilles always compromise the sound of speakers. It is not as bad as putting a blanket over the speakers, but it similarly does always muffle the sound a bit.

Well, I have been busy listening to music all day so I have not written anything yet.
It is safe to say they are not going back!

Take your time, Donald. You have grown use to the sound over the years of tweaking and settling in of your old speakers and now you have get use to a new sound from your FR30âs. Donât forget, new speakers take a while to break in, maybe even longer than electronics and cables. There are drivers, crossovers, and internal wires you have to loosen up and burn in. Then thereâs the matching of right cables, electronics, and parts to the new speakers. I wish you good luck.

You are so right! FR30 sound is changing by hours. I will probably let Stier2704 wait a bit longer.

You are welcome to share with us your impressions from the first note about the valley and mountains of burnin. Maybe interesting how it changes. When I changed the duelund capacitor, it took about 2 weeks until the syllables were traced cleanly without any slight sharpness or hissing. Some singers I thought had a gap in their teeth. The Milflex had an up and down in tone in the first week. The film capacitors require up to 500 hours to reach their full potential. With MKP capacitors it goes a little faster, usually after a day or two they lose the initially somewhat rough tone and become more smoother organic in sound. Solder joints have a harsher sound in the first few hours. Youâve experienced how long it takes with cables with the PSR 11. The coils and resistors also need some time. The basses will also need a few hours/days. There shouldnât be a long break-in period for the tweeter and midrange foils. At the beginning it often sounds dry and a bit more aggressive. Over time it should sound smoother and more open First, what kind of feet are those under the FR 30?
