RCA Switch Stereo 4 in 1 Out Audio Signal Source Switcher HiFi Input Selector Splitter Box S1

Let's face it, when in the market for RCA cable switchers, one usually finds a variety of cheaper made models and it's not unusual to see the same model being marketed under different brands. This is often par for the course with these inexpensive Chinese branded models.In my case, I have 6 different DAC's that I use with my desktop PC, attached to a variety of speakers. Yes, I do online reviews and provide comments regarding performance characteristics of different pieces of equipment.So last week I began to look for a good 4-unit RCA Audio cable switcher. And mannnn, there were tons of them on Amazon - most were very cheap in price, while a few ranged between $100 and $200 USD. I was eventually eyeing one that cost close to $200, when I happened upon this GOHIFIAUDIO S1 switcher.I thought, "Hmnnnn, they want $70 USD for this thing (at the time of this writing - they've gone up since then)?" I was hesitant at first, mainly because it had no reviews, and also the thought (assumption) that any type of cable switcher will result in signal loss - especially with passive models (of which this model S1 is one). But being the guinea pig that I tend to be, I pulled the trigger and purchased it.When it arrived, I noticed that the box seemed heavy (a bit more than I expected). When I opened the box, I was dumbfounded (in a very, very good way) to see a solid brick of a switcher. Beautifully machined and exceptionally solid (thus the weight of the unit), you could see that this was not going to be no ordinary every-day switcher. The RCA inputs on the back were meticulously designed and constructed and durable and you knew right away that you were dealing with a higher end device.But how would it sound? I immediately connected several DAC's to this unit. By the way, for those not familiar with the term "DAC," it's short for Digital to Analog Converter which can make a world of difference with sound quality on the likes of a PC or a video system. When I selected switch #1 - which happened to have the iFI Zen DAC unit, I could not believe my ears. No signal loss or alteration at all - what you listened to is what you got. And the switching back and forth (between 4 units) is so smooth and high-end, that it will put a smile on your face. And no worrying about using the right power supply as this is a very basic passive unit, that was exceptionally crafted/machined. The moment you handle (pick up) and use this Model S1, you'll be hooked and then wonder why you haven't seen this thing before.So right now I have the following DAC's attached to this GOHIFIAUDIO S1 - those being the iFI Zen DAC, the Schliit Modi 3, the Micca OriGen2, the FX Audio DAC X6, and the Sabaj D3. Switching between them to do a budget DAC audio evaluation was effortless.Another question that folks often have with regards to the possibility of using an RCA audio switcher, is will thick cables (and bending them to connect to other units) result in the switcher being lifted up, or turned in a particular direction. This happens big time with thicker, less pliable cables. I can tell you that in my case, I have each DAC connected to the S1 switcher with a shorter 1 foot RCA cable and the only result was that the smaller DAC's had to be turned somewhat - but the S1 switcher was solid and stayed put!So folks, I'm just one reviewer, but my listening standards are high. I'm gratified to have found this particular Switcher on Amazon. This comes highly recommended! Caveat here - remember, reviews are subjective and all I can do being an audiophile is to call 'em as I see 'em. YMMV.....EDIT - Add-on comments as of 6-29-2020:I just wanted to add on here that I purchased a 2nd switcher due to the fact that the first one was so awesome. I have additional components (i.e. DAC's) that I needed to bring into my system, so I got another one. I'm telling you, this passive model is built quite well and just plain works - without any signal loss or alterations!!!!Since I purchased the first GOHIFIAUDIO S1, I also tried another switcher that was not passive - it had to use a power supply. It was a Chinese made product also, but it failed after two weeks (the right channel stopped working on the 2nd set of RCA inputs). So I had to return that one. That made me realize that you stick with what works best, and that's why I purchased another GOHIFIAUDO S1. The GOHIFIAUDIO S1 sets the standard in my book.And yes, I know it went up in price - like some $20 more - but hey, it is most certainly worth it as you get what you pay for.

Nothing much to report other than it works perfect and seems to be build very well. Great product with zero noise!

Well made. Good terminals. Solid box.

It does what is intended, but it leaks signal onto adjacent channels. Most of these switches do, but this one is quite noticeable. If you are using it in a studio or setting where this switches an input signal between multiple amplifiers/outputs that stay hot all the time, you may have detectable audio output on more than just the selected system. While it is very quiet, it is there and can be heard. I use it in a setup where only the selected amplifier is powered up so it's not an issue for me. It is, however, all metal and fairly well made, but the selection knob does have a little up-down/side-to-side play in it. The knob is connected to a shaft/rod that turns a switch on a PCB that is mounted to the back plate of the switch housing. It was done that way to eliminate the need for wire, but would have been much better quality if the switch was mounted on the front plate and wires ran to each input/output instead of using a PCB. This would have eliminated pretty much all signal leak, but wire is expensive, of course.

Listening wise its like its not even there (in a good way). Totally passive. The knob felt a little janky but its because the screw needed to be tightened and thats not a big deal. This is not an industrial design masterpiece. Its just the exact switching mechanism you are looking for built into a generic project box. That said it does look good next to my stereo components. I recommend using Monoprice RCA cables with it. They are inexpensive and quality made. A little stiff to bend around in back of a stereo but thats okay too. Good sound is worth it. :). There are a lot of junk RCA switchers out there...and RCA switchers are little empty boxes for the most part... but it was either buy this perfectly adequate switcher or build one myself. If you did go that route by the time you ordered the stuff from a direct electronic components warehouse in China, had it sent, waited the 4 weeks and then soldered it all together I bet you would, in the end just end up with something exactly like this product anyway. They just went and did it all for you here. SO spend the extra money, buy this ready made box and go enjoy your music! RECOMMENDED.I bought the 4 channel Solupeak S1 version with gold RCA in/outs. Dunno if I really needed to upgrade but I did and don't regret it :)

You could certainly build a simple RCA switch-box yourself, but after opening this thing up I don't think you could build one yourself as good for the same money. Nice quality switch and nice tight fitting RCA connectors well soldered to a PC board stuffed in to a well made metal project box.I have one preamp and one pair of speakers. I switch between two power amps. I've been using the SOLUPEAK speaker switcher for close to a year and it's been faultless. For the inputs, I was just using a pair of RCA "Y" connectors. Decided it was time to ditch the "Y" connectors and add a switch for the signal inputs as well. SOLUPEAK again had what I was looking for. Silent switching and zero detectable signal degradation.I make my own shielded interconnects out of Mogami 2549. With the shield connected only on the source side, I have no issues with ground loops. I only mention this because in the description for this item it mentions possibly needing a ground loop isolator. With a properly thought out cabling and grounding scheme, you'll never need one of those items.Anyway, this little box is well worth the price and works perfectly.
