    Building a system around ROON for local/ripped/downloaded files and making it better than CD playback...

    There's definitely that. For example you like and recommend Supra CAT8 and Melco C100. I find they both sound overly bright and musically uninvolving. Lots of people on WBF love the Sablon 2020, whereas I find it sounds too dark and lacking in microdetail. I agree that ethernet cable...

    Building a system around ROON for local/ripped/downloaded files and making it better than CD playback...

    I don't use Roon, but as I understand it, the Roon system consists of a server and a client. I believe the variable sound quality is due to the client software. You can use Roon server with another controller, like Squeezelite, BubbleUPnP, Linn Kazoo and others. I have heard Roon server with...

    Building a system around ROON for local/ripped/downloaded files and making it better than CD playback...

    I have a couple of friends who use a K50 with Roon server. They were surprised to find that adding a switch improved the sound, even when playing from the K50 hard drive, where the LAN connection is only needed for control. I believe this is due to ground-plane noise.

    Building a system around ROON for local/ripped/downloaded files and making it better than CD playback...

    This needs clarification. The best CAT8 cables I've tried (Furutech, Audio Sensibility, Synergistic Research) sound significantly better than the CAT6 and CAT7 cables I've tried (BJC, Melco, Sablon). You just have to use them appropriately. My thoughts on this from another post...

    Can a Linear Power Supply Inject Noise Into its AC Circuit?

    I forgot to mention one of my tests. I use a miniDSP digital crossover for my subwoofers only. Powering it with an iPower2 SMPS generated tighter bass than a Topping P50 LPS, which reinforces my belief that "it depends".

    Can a Linear Power Supply Inject Noise Into its AC Circuit?

    I know Hans Beekhuyzen holds the same opinion, that pure digital gear like routers and switches are best used with a switch mode supply, but IMO it's not that simple. I own iPower 5v and 12V and an iPower X 9V. I have tried these with various renderers, DAC's and switches in my four network...

    Bryston Cubed Amps in Bridge Mode

    They become 3-ohm Harbeths to a bridged amp, and even lower at some frequencies, and an extreme current demand. Also distortion increases when bridged. If you prefer to use two smaller amps, I suggest vertical biamping instead of bridging. It will sound significantly better.

    Fiber vs. Ethernet sonic differences

    But unlike an SFP module, there is no optical fiber conversion. "DAC cables (Direct Attach Cable) are nothing more than two twin-axial copper cables (one for each direction) terminated to a near-empty circuit board that has SFP edge contacts. Since the signals connected to an SFP cage are just...

    Network Acoustics - Tempus network switch

    Was that the original oMD? V-2 is supposedly a much improved version. I agree the power supply makes all the difference in the world. I use a Teddy Pardo MiniTeddy into an ER with Pardo 12/2 LPS, via single mode fiber. No doubt there are better, and the price delta between the Tempus and ER...

    Network Acoustics - Tempus network switch

    John's explanation ignores that the great majority of SFP ports are embedded in a switch, which reclocks and reduces noise. The opticalModule is a great FMC, but also a switch

    Network Acoustics - Tempus network switch

    I agree, except for the EtherRegen, which was purposely designed for audio, and has features not available elsewhere. Add your favourite power supply, it competes with anything on the market. I have compared the ER with Teddy Pardo PSU to a Silent Angel N16 and LHY SW-10, in my system and a...

    Legendary Supex 900 Super: Koetsu before Koetsu

    The trouble with swapping the Supex in and out is that the pins are smaller diameter than any other body I've used. Squeezing the clips on an arm with integral headshell is no big deal but expanding them again is scary. I am emotionally attached to that cartridge Leif. I'll be interested to...
