Tertullus 2Pack RCA Audio Cables, 6N OFC Braided RCA Male to Male Stereo Audio Interconnect Cable for Home Theater, HDTV, Subwoofer, Amplifiers, HiFi Systems (2M / 6.6FT)

Just hooked up two of the 2M RCA cables to my vintage 70’s stereo system between the preamp and tube preamp. There was a noticeable increase in the highs. I turned the preamp treble down to flat and now sounds excellent. I have 2 shorter cables coming to complete the chain from the equalizers to the amp. Looking forward to the increased dynamics. Easy install. Make sure to follow the arrows on the shells and the tighten them for a perfect connection.

Review is of: Tertullus RCA Cables, A10 Cable RCA to RCA Male 6N OFC Copper HiFi Audio Cable . . .TL/DR: Can't tell if it improves the audio- it's hard to test that. It works well as a sturdy/reliable audio cable, it's well-made.You may have some issues with bending the cable if your equipment is close up against anything, there needs to be about 3 inches for the cable to plug in and bend around the corner.

This set of RCA subwoofer cables is seriously impressive quality. I didn’t know that the quality of sub cables could make such a difference in ones sound system. Using these cables has instantly solved the humming subwoofer problem I've been dealing with since day one. As soon as I plugged it in the faint hum that had become omnipresent and ubiquitous in my room disappeared and I was surprised how quiet and nice my room suddenly felt. I believe that the problem was solved because these cables are shielded and the one I was using before was not shielded. The connecting jacks of these cable are super beefy, all metal, and are obviously made to last. While that is definitely a positive, it could also be a slight negative… because the jack is so beefy and large, it sticks out and requires a couple inches space between the subwoofer and the wall. Because of this I wasn't able to push my sub all the way against the wall how I like, but it is a minor inconvenience. These RCA cables are easy to recommend , they may be priced a little higher than basic RCA cables, but its easy to see they will have a much longer lifespan. In addition to all those positives, they also just look really good and professional. This 2 set of RCA subwoofer cables are an easy 5 stars.

The Tertullus Hifi Phono cables (2M length) are well-made with locking RCA connectors, and are nice looking. Cables are directional, so beware to install the cables with the arrow facing the proper direction.First compared these cables to the inexpensive cables that typically come with a CD player. Cables were connected to the RCA inputs of a home theater receiver (Yamaha) and a Bluray player (Sony). The Tertullus cables provided better soundstage, bass, and depth as compared to the inexpensive cable. The bass if present in the music was not overbearing nor boomy. Would say the cable has a neutral sound. Connected a single Tertullius cable to the digital input of a CD transport with a separate DAC converter connected to a separate tube preamplifier and solid-state amplifier and compared the sound quality to a $100. After a few hours of listening, the $100 cable which has a solid silver center, sounded a tad better than the silver plated Tertullus, with slightly better soundstage and clarity of instruments/detail. It was not immediately obvious and did require a lot of switching of cables back and forth to make that determination. Since the Tertullus is labeled as a phono cable, tested the cable (pair) on a turntable (Project) with a phono preamplifier (Cambridge Audio) and the same preamp/amp setup as the CD transport test. It was surprising, the sound was a little shrill (highs felt a little too high) and bass was missing a little, as compared to sound quality on CD playback. Not sure why that was the case, can only rate as 3-stars

The Tertullus HiFi Phono Cable A10 Audiophiles RCA Cable Male to Male HiFi Interconnect Cable looks very well made and has heavy duty connections. I decided to try these cables when the cables that came with my wireless speakers started going out. At first, I wasn't able to connect to the speakers because the connection point was too narrow. I removed the outer shield and they connected fine. The speakers now sound really nice.
