I've been wanting to add the CL-1 to my setup for quite some time. So far, I'm super happy. I use this with my SM57, and the difference between with and without is night and day. There is no noise whatsoever, which is super ideal. I pair the CL-1 with the Xvive P1 Phantom Power to, not only give the CL-1 phantom power but also to record louder instruments at lower gain stages (switching to 12v rather than 48v). This pairing is a perfect match for anyone who records their own music. I highly recommend the CL-1 to every producer.Paired between a Maono AU-AM100 and a Heil PR35. Works great and really gets the level up to where it needs to be. Before I'd have to max out the XLR Mic1 gain and slide the mixer to the top. Now with "MAX" selected and the impedance set between 1.5-3kOhms and the HPF off. I have some fan noise from the computer, so using the nVidia Broadcast app to remove that, and everything sounds great.This makes an SM57 sound phenomenal! Tested it using the Cloudlifter against much more expensive microphones, and the SM57 + Cloudlifter sounds better. This one done using an audio interface that already has excellent preamps, the RME Fireface UCX. There is also significantly less noise when using this unit with the mic. Highly recommended, and far better than the Fethead. The Fethead added a significant amount of noise and didn't sound good.The CL-1 is worth the price, and elevates mics like the SM57 to a much higher level of quality. Better pickup, better sound quality, and less noise. And this is also the case when compared to using much more expensive condenser mics.The first time I bought a CloudLifter was probably a month after I bought my first audio interface. I had the M-Audio FastTrack Pro, and it had weak pre-amps that were very noisy on higher settings, so I had to choose between not hearing myself or hearing static, and the CL-1 gave me the boost I needed. Another nice aspect of it was that it had the right impedance matched to my mic, which not all modern equipment does, so the mic sounded much better. Fast forward to years of wanting to try the variable resistance / impedance of the CL-Z, and that desire increasing when I saw that it now has a 1/4 inch instrument cable input, for things like guitars and bass guitars. Having ground lift was an additional bonus I liked. I still would not commit, because it wasn't a real need. Then, I started hooking my PA system up to two mixing boards in a bar and found I needed more than one addon pre-amp, for a special purpose, so I made the purchase of two more CL-1s and a CL-Zi, to sample what I had been missing.CL-Zi has been a lot of fun to play with. It's resistance options allow you to control how stiff the diaphragm of the mic is in a way that is very similar to how your hearing quality changes when your ears are adjusting for an altitude change in a plane. Turn the knob far enough one way, and things are crisp but have no strength to their sound, and in the other direction you can go far enough that a voice is so deep and bassy as to be harsh, but the sweet spots in the middle offer lots of options. It also comes with a high pass filter that changes the sound of the low impedance side of the spectrum, making it much more pleasant to the ear.The last thing I love about this product is having two levels of mic pre-amp. My old audio interface needed the full gain a CL-1 provides, but my new interface has clipping issues with the full gail, unless I enable the pad, so being able to use half gain keeps this product useful across all of my gear. If I had bought a FetHead or stayed with a CL-1, I also wouldn't be able to get use out of it to season the sound of my instrument pickups.The cons are the price is a little high and the case isn't as radio-proof as I would like. My GSM phone can be heard if it gets too close on the desk to the CL-Zi, slightly less so with the CL-1, which may not be a problem I should complain about, but was something the abnormally strong metal case of these products had me hoping wasn't an issue.My comment about wishing I could give 4.5 stars is because it took a return to get one without a chip in the paint and rust on it, but the second shot was very satisfactory. Don't be afraid to send back a damaged product, as the customer service experience was great.Works great, sounds great, definitely boosts my shure mic does what it’s supposed to do without any hiccupsThey say my Clarett 2Pre will power my SM7B. If I crank the gain to max, like they say to do, I hear lots EM noise. This thing allows me to stay just before 8 (0-10) and it sounds great, no noise.Excelente productoI've used both a Blue spark mic and a Shure SM7B and both require post production edits to raise the volume. Turning up the gain on my pre-amp simply wouldn't cut it since it introduced the inevitable hiss. I noticed that many people recommended the Cloudlifter and a 'must-have' if you own an SM7B. Since I just bought an SM7B and was witnessing the same need to pump up the volume, I took the plunge.No power is necessary which is a bonus, since it draws the phantom power from the pre-amp and essentially powers itself (and obviously the mic). There's nothing to shout about other than the unit does EXACTLY what it reports to do. It raises the volume of the mic without any unwanted noise. The phantom power is not eradicated using a dynamic mic, it's EMPLOYED - as it should be!The result is that I'm managed to be able to reduce my gain by a quarter on the dial...and no post-production volume changes are necessary! Perfect! This takes away from my workload since I churn out instructional videos by the dozen and something forget that I need to pump up the volume.The unit is solid metal and built like a tank. I imagine this to be the ideal solution fr those people who might use this in the road. though mine is 'on display' lying on its side with the logo showing, the unit has large rubber feet which allows it to sit securely on a desk. The XLR's snap in nicely and firmly.There's shady copies of the cloudlifter on the market for a fraction of the price, but people have stripped them down to see that the 'meat' inside is far inferior in contrast. The copies produce a loud of unwanted noise too.I'm with those people who recommend the cloudlifter for the SM7B, since it works a charm. I see no reason why it wouldn't work great for other dynamic mics too. If you're looking for that boost in volume, just buy one.Ce produit est juste incroyable !Il est pour commencer d'une solidité exemplaire ! Ce qui rassure vu son prix !Il m'a permis de booster le volume sonore de mes enregistrements vocaux avec mon SM57B ! Un pur bonheur !Je le recommande à toutes personnes utilisant un micro du même style, ce qui vous permettra vraiment de gagner en gain sonore !AFIN DE PARTAGER MON EXPERIENCE AVEC VOUS, SI CE COMMENTAIRE VOUS A ÉTÉ UTILE,MERCI DE CLIQUER SUR "UTILE".I have a Shure SM7B which requires a lot of gain and my Focusrite just didn't have enough to drive it well enough without introducing too much noise. The Cloudlifter is fairly pricey for what it is, but once you hold it in your hand you realise what a quality peice of kit it is. It's larger than I imagined it would be and has a nice weight to it - I feel as though it would be quiite durable if you were to take it on the road with you. It has boosted my Shure SM7B perfectly, nice clean gain and really easy to set up - just plug in with XLR cables and turn on the phantom power from your audio interface and you're done. Money well spent.Make sure you have two XLR cables as you'll need one to go from your microphone to the cloud lifter and then another one from the cloud lifter to the audio device!Used this to boost the audio for my Rode Procaster when feeding it into the Focusrite Scarlet Solo 3rd Gen, works really well, absolutely recommend!Great built quality and no setup required beyond plugging it in.I bought the Cloudlifter 2 after watching a video on YouYube to get the most from my Focus Scarlett USB audio interface.It's undoubtedly a well-built bit of kit and looks good. I set everything up with a friend, and we made some recordings. Neither of us could notice any difference in the quality of the recordings; maybe it would make a difference if you were using very cheap mics, yet if that's the case, you'd be better off buying decent quality mics for less money.The Cloudlifter 2 didn't appear to improve the sound going through our Focusrite Scarlett 2i2 3rd Gen USB Audio Interface. It only made the setup more complicated with more leads to connect.I haven't used it since; I leave it lying around as it looks cool. I should have sent it back for a refund as it's not needed. I doubt anybody with the funds to afford the Cloudlifter 2 would be using cheap mics that are so bad you need to buy one of these if they were serious about recording.An expensive but not needed gimmick unless you are out to impress someone who doesn't know anything about sound engineering.
