Matrix Audio SS-1

The SS-1 makes the same argument as the SS-1 Pro, at a lower price and with a simpler clock system. A network switch running well above its operating speed ceiling is more stable than one working at its limit. The SS-1 has two 10Gbps SFP/SFP+ ports and four RJ45 ports at up to 2.5Gbps. Your audio equipment connects at 1Gbps or 100Mbps. The headroom is substantial, and that headroom translates to lower timing errors than a conventional 1Gbps switch would produce at the same actual data rate.

What separates the SS-1 from the SS-1 Pro is the clock system and the power supply. The SS-1 uses a femtosecond oscillator as a direct reference for the main controller — serious, but without the RF synthesizer and external clock input of the Pro. The power supply is a switching design rather than the SS-1 Pro's o-core toroidal linear supply, with a DC input that accepts an external linear power supply for those who want to go further. For a well-sorted streaming system where the switch is the last piece rather than the first, the SS-1 is a credible destination.

The Clock

An ultra-low phase noise femtosecond oscillator serves as the timing reference for the SS-1's main controller. This is the same class of oscillator used across the Matrix N Series and M Series products — the choice reflects Matrix's consistent position that clock quality matters in every digital component in the chain, not just the transport and DAC. The SS-1 Pro adds an RF synthesizer between the oscillator and the controller, and an external 10MHz input for SC-1 pairing. The SS-1 has neither. If you are running an SC-1 and want to discipline the switch from the same reference, the SS-1 Pro is the right product. If you are not, the SS-1's femtosecond oscillator is a meaningful improvement over what a standard switch provides.

The Ports

Two dedicated 100Mbps/10Mbps RJ45 ports are provided for audio equipment — the same dedicated low-speed audio ports as the SS-1 Pro. Lower connection speed for audio devices reduces potential bit errors during data transmission, and the independent socket design with wider spacing accommodates high-end Ethernet cables without crowding. All Ethernet transformers are 10Gbps-grade, individually metal-shielded per port — radio frequency interference resistance built into the port hardware rather than relying on enclosure shielding alone.

The two SFP/SFP+ ports accept optical fibre or copper modules at up to 10Gbps. Running the upstream network connection through an SFP optical module creates electrical isolation between the upstream network infrastructure and the SS-1 — ground-borne noise from routers, modems, and upstream switches has no copper path into the audio network. The four 2.5Gbps RJ45 ports handle the remaining wired connections. The SS-1 Pro has six 2.5Gbps ports; the SS-1 has four.

Power Supply & DC Input

The SS-1 ships with a wide-voltage switching power supply. It also has a DC input — 12V ±10%, minimum 18W, 5.5mm/2.1mm barrel connector, centre positive — that accepts an external linear power supply. When DC is connected, the internal AC supply disconnects automatically. The external supply feeds the femtosecond clock and the main controller through an internal power filter and four ultra-low-noise LDO regulators. A linear power supply on the clock section of a network switch is audible in a system that is otherwise well resolved. Matrix has made the upgrade straightforward.

The SS-1 Pro's internal linear supply — o-core toroidal transformer, Schottky diodes, ~10,000µF audio-grade filtration, six LDOs, passive heatsink — represents the ceiling of what the DC upgrade path on the SS-1 is trying to reach. If you are certain you want the full linear supply from day one, the SS-1 Pro is the direct answer. If you want to start at a lower price point and upgrade later, the SS-1's DC input keeps that option open.

Practical Details

Port LEDs are switchable off via a button on the rear panel — necessary in a darkened listening room where activity lights in peripheral vision disturb the experience. The 16K MAC address table is shared across both SS-1 and SS-1 Pro. The CNC-machined aluminium chassis sits on a reinforced steel base. Four isolation feet are included; three-foot placement is supported for surface compliance and tuning.

Where It Fits

The SS-1 belongs at the last network node before the audio equipment — between your existing router or upstream switch and the Matrix streamers or other network audio devices. With an optical SFP module on the upstream port, the electrical isolation between the network infrastructure and the audio equipment is complete. With a quality external linear power supply on the DC input, the power supply is elevated to a level that approaches the SS-1 Pro's internal supply.

Against the SI-1 network isolator: the SI-1 is a two-port pass-through that adds isolation for one downstream device without replacing the upstream switch. The SS-1 replaces the final switch in the chain and handles multiple devices simultaneously, with isolation built into the SFP port architecture. If you need to serve several audio components from a single switch — a streamer, a Roon core, a second room — the SS-1 is the right solution. If you have a single audio device and an existing switch you are happy with, the SI-1 is simpler.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D

Weird smell
Color: White-cooling Basic, Size: Queen(Pack of 2)
The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.

helped treat my sore neck
Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.

Love them!
Color: White-cooling Basic, Size: Queen(Pack of 2)
Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!

Soft and smooth cover
Color: Grey, Size: Body(20"X 54")
This is a nice pillow cover overall. The fabric feels good and it's comfortable to sleep on, especially compared to a more basic cotton cover. It is maybe a little thinner than I expected, so if you want something thick and heavy this probably isn't that. But for a soft smooth cover that fits and feels decent, I think it's worth it. No major complaints from me after using it.
