How does this 1.5 m cable compare with no cable at all - ie when the streamer is built into the DAC? Or for that matter how does the DAC to preamp cable connection compare with no cable ie in an amp with built-in DAC? Let's finish the chain by again comparing the link between preamp and power amp - cables vs integrated?
For my money (saved money), I avoid as many cables as possible. The cable that improves sound hasn't been invented - and never will be, however much it costs.
I wholeheartedly agree "The cable that improves sound hasn't been invented" however I have heard several that have spoilt it. including digital,optical & analogue. a good cable does nothing more than transmit an unadulterated signal, some don't, sometimes they act as a filter improving the sound in a very limited application usually the converse is true.
Is Bluetooth as good as WiFi both require conversion from and to, then to and from, are the converters of a consistent standard as far as I can see it never stops whether cable or through the ether. The SPDIF article I posted probably explains the pros & cons of built in DAC's I believe careful attention to detail is the answer.
I use 75 Ohm F type fittings for coax connections in my system the CD4se player I use for a transport is BNC crimped then soldered, where RCA/phono type sockets are fitted F type fittings have screw in RCA/phono barrel's like the aerial fitting but with a longer center pin. I also use an F type switch box between CD & DVD player to DAC. all with WF100 75 Ohm coax full copper foil/mesh shield. Pus a load of clip on ferrites.
All to make the best of what I have with no additions like jitter/internal reflections or losses due to any cause ie impedance mismatch. On another forum I was described as having dealt with the minutia in my system.
I also made my fine silver phono leads & cross-connected coaxial speaker cables, I use the TNT UBYTE 2 Cable. the effect that occurs is an inductance reduction to almost nothing. perfect for my OTA Quad 57's that require very low inductance ref. Sanders white paper & a plethora of others.
My working life taught me the devil is often in the detail. Now I have the time to attend to the minutia, research on forums talking to friends who design professionally/build not only HiFi, off the internet, I have not thrown much money just attended to all the details I could conceive, the result is I am pleased with what I have.
