*(special order) Naim Amplifier compatible Bassline Blue 10 meters

The special and unique characteristics of our filter board are known only to our engineers and within this circuit lies the key to designing cables optimized for REL Sub Bass Systems. Available in 3M, 6M, and 10M lengths. Naim amplifier compatible Bassline Blue cables available in 3M and 6M lengths.

Sound illuminated

The ultimate upgrade

Bassline Blue™ is a sensibly-dimensioned cable, well-constructed so that it will improve the overall sound of every aspect of the host system’s performance. As with any REL product—the improvement extends well beyond the obvious bass region. The greatest area of improvement lies in the manner in which the entire soundstage is illuminated. This is a quality quite different from brightness. Illumination acts to bring light into the stage and renders contrast and clarity as well as dynamic shadings much more evident.

What’s In a NAIM? These same benefits are available to most NAIM owners—especially the older, classic models. These units feature an unusual output impedance that is quite complex. REL worked closely with NAIM engineers to model this behavior and arrived at a special circuit built into each NAIM cable that replicates this impedance so that it is safe to run Bassline Blue on early NAIMs. We even sourced a wonderful stackable banana plug that makes it so easy to use the cables, just plug them in to NAIM’s flush-mounted chassis banana sockets and then plug your speaker cables directly into the rear of our stackable banana plug.

Natural Drawn Copper

Quality born from system thinking

Beyond optimizing the geometry of the internal lay of the cable, we also employ copper that exceeds industry practices and is of a quality and type generally specified for military use and high speed telecommunications. Bassline Blue is constructed of slow-drawn, high purity copper, drawn in a nitrogen bath to minimize impurities on the surface of the wire. Each individual conductor is coated in a Teflon film immediately upon leaving the extrusion die to ensure that impurities cannot impinge on the cable while awaiting further processing. This technique produces a sound that is exceptionally pure and natural which we term Natural DrawnTM wire. Bassline Blue is hand constructed at our California facility using cable produced exclusively to REL’s specification by a North American OEM wire and cable house. Construction is quite labor intensive and can require up to one hour per cable. We use pure silver solder for all connections which ensures not just high quality sound, but also as the cable ages and oxidation sets in sonic degradation should be nil due to the conductive properties of pure silver.

Connect Like Never Before

High Level = High Performance

REL employ Swiss-made Neutrik SpeakOn connectors at the input to the REL sub bass system. In over 100,000 RELs in use the world over, this connector has proven itself reliable, neutral and a mechanically ideal connector for REL’s renowned High Level Input circuitry. BLUETM also features high quality spade lugs coated in gold to minimize oxidation. Should your amplifier require a bare wire connection, this is easily accommodated by manually re-terminating the individual red, black and yellow leads. The standard high-level hookup procedure is: attach the red wire to the amplifier’s right positive speaker output terminal; attach the yellow wire to the amplifier’s left positive speaker output terminal; attach the black wire to whichever of the amplifier’s ground output terminals is convenient; plug the Speakon connector into the Sub-Bass system’s high-level input.

Huge Upgrade to my trusty V1 Robot
We've had one of the first model robot vacuums from the og manufacturer which has been a workhorse for us for years! It's the drunk uncle of robots though, no bells and whistles, just your basic robot that runs into everything but gets the job done in some random chaotic pattern. Seeing this on sale and finally just going for it to see how good newer models have gotten (no more separate virtual wall lazers, a nice easy to use app, no more bumping around clumsily!, and more). Well, long story short, they have gotten soooo much better and I'm incredibly glad I gave this one a try. It's is running flawlessly, cleans very well, i love the ease of the app and setting up no-go zones, and pretty much everything else has been an upgrade. Looking forward to many years of our new bot and a cleaner, less noisy, less drunk uncle of a bot around the house. (Don't worry, drunk uncle is still getting his time in down in the basement. He's old reliable at this point and will go as long as he wants to.) This is a great vac that performs wonderfully with all the functions and conveniences I need (i haven't tried the mopping function yet but didn't really buy it for that) at an incredible price point, esp when on sale. If you're looking to upgrade like I did, it's well worth it. If you're looking at your first robot and are unsure if it's something you really need.... trust me, get it. It will save you time, knock one thing off your million item to-do list, and will soon become something you are unsure why it took so long to try.

Updated Review: error code and quit working after only 3 weeks.
Update! I absolutely loved this vacuum.....for about 3 weeks. I ran it every day. I loved loved loved the mapping feature that allowed me to select which rooms of my house I wanted it to clean. It did a pretty good job and I was so happy with it. I took good care of it and cleaned the filter and emptied it often. It was great ...until it didn't work anymore. Fan error: error 155 called for me to factory reset the vacuum which I did 3 times but it still wouldn't go more than about 30 seconds before stopping and giving me the internal error code again. After researching the code (because the website and help book on the app don't list this code in their troubleshooting guide) apparently this is a common thing for this particular model (the Q5 pro) to do. And most of the time it isn't fixable. We were still within the time frame to return it through Amazon so we decided to do that rather than contact customer service in hopes that they might fix it but not and then not be able to return it anymore. Sadly I won't be buying this brand again for a while. My previous vacuum (roomba) lasted me 5 years and still works, just has old technology. I was really hoping for another vacuum with newer technology like house mapping to last me a long time as well. I most likely will be returning to the Roomba brand. Which is sad because this seemed like a great vacuum with great features for a good price. I hope roborock improves their models and fixes these error issues and maybe one day I'll give them a try again. Maybe. Original review: I love this vacuum. I had another brand that was 5 year old technology and just caused more headache than help. This one is a huge improvement. I love how it initially mapped out my house and I was able to divide and name the rooms in the app. Now I can tell it to clean only certain rooms or the whole house and it does great and doing only the rooms I want it to do. I connected it to my Google speaker as well and now I can tell google to make my roborock clean my kitchen. I can also control it and monitor it from the app even when I'm not home. The mop feature isn't great. It really doesn't clean, more just puts water on the floor and leaves dirty streaks. But I didn't buy it for the mop function. If it does a great job vacuuming, which it does, I'm happy with it.

Amazing!!!
Color: White
I purchased the OKP Life robot vacuum in 2024, and as of 2026, it continues to perform exceptionally well. It has proven to be a highly reliable product, exceeding my expectations in terms of durability and long-term performance. This device has significantly simplified my cleaning routine and saved me a considerable amount of time. Its suction power is sufficient to effectively remove dust, crumbs, and pet hair without difficulty. Additionally, it navigates around furniture efficiently and rarely becomes obstructed. Another notable advantage is its relatively quiet operation compared to traditional vacuum cleaners, allowing it to be used at any time without causing disruption. It is also very user-friendly and maintains a consistently clean environment with minimal effort. Overall, I highly recommend this vacuum. It is dependable, well-constructed, and represents excellent value for its performance.
