I think my trouble may be because I am trying to use one or more of the adaptors/leads the wrong way round, because it became apparent when wiring it up that I had misplanned 2 male/female connection points. I agree with others, the Gram Amp is a piece of junk, I tried it and immediately knew it was junk so I sent it back. Or you might just want to upgrade its sound beyond what's possible with the built-in phono stage found in amplifiers or some record players. I might just live with one source via optical and foregoe HD audio on there for the time being - until I can afford an HDMI amp. Then you'll likely need a phono preamp (aka phono stage), which raises your turntable's audio output to make it compatible with line-level modern amplifiers.

The ugreen phono splitter box provides superior stereo audio transmission and protection against radio frequency interference (rfi) and electromagnetic interference (emi). It's a wonderfully clean and crisp sound, with more low-end weight and substance sitting alongside Cyrus’s traditional values of precision and speed.The smooth, full-bodied performance, coupled with the inclusion of a headphone amp, makes this stylish box certainly worthy of consideration. I am already splitting that output to create 2 stereo versions of it to then route to 2 different places. And, this is made of tpe and bulletproof wire, and has anti-sway up to 5000+, which protect the cable from being broken. We love the scale of performance and the way the Vertere delivers the seismic dynamic shifts of the recording with so much enthusiasm.

Multi-purpose phono preamplifier with A/D conversion and 2 output options: Line level and digital optic!Musical Fidelity takes a different approach: this phono preamp is beautifully made, with a smartly machined front panel and nice-to-use controls. I guess as long as the materials match the quality of the plugs in the interconnects then there won't be any degradation of sound quality from the extra connection. jack audio cable also allows you to connect a dvd player, tv, wii box, video camera, vcr, or other equipment with legacy rca connectors to speakers or av receivers with a 3. I'm planning on using Van Damme cable for the interconnects so i thought perhaps the soft splitters as shown in the picture above would completely remove the advantage of using quality cable.
