## Questions & Answers

**Q: I am looking to make the audo louder from my computer to amplifier will this do it? thanks**
A: Not really . . . : A preamp (and this is a preamp) only raises the volume of the signal slightly . . . an amp, or amplifier raises it to levels that can power passive speakers.  Active speakers have an amp built in.  So, you can go from computer to an amp, or from a computer to powered speakers and don't need a preamp.  Or, go from the computer to this preamp, then to an amp or powered speakers.  You don't NEED a preamp at all if you have an amp, but you can use one if you want to add a volume knob in between the source and speaker, or want to add a tube pre like this for 'color' to alter the qualities of the sound.  Sounds like you want an AMP not a preamp otherwise.

**Q: I'm using philips shp9500 headphones. at a maximum of 32 ohms, could i just combine my headphones with this pre-amplifier without an amp? (pc dac)**
A: This is a pre-amplifier, not a headphone amplifier. Headphones like the Sennheiser HD6xx could be used because of their high impedance (600 ohms) at a low volume. The 32 ohm Philips headphones may cause issues with this pre-amp.

**Q: Can i use this product from a 3.5 mm headphone jack on a tablet to a rca line input on a stereo receiver?**
A: Yes, you will need to use a cable that has RCA plugs in one end and a headphone plug (1/8") on the other. The headphone plug goes into the tablet and the RCA plugs go into the input of the SUCA-AUDIO. You will use another cable with RCA plugs on both ends. Plug in the RCA plugs on one end into the outputs of the SUCA-AUDIO. The RCA plugs on the other end go into your stereo receiver inputs.

**Q: What other tubes can I upgrade this with? Thanks**
A: Get the readily available Riverstone Matched pair 5654W from Amazon, or there are lots of varieties on eBay to try! 

Voshkod 6j1P's sound amazing in this.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great preamp with a few small caveats.
*by G***L on June 30, 2021*

I’ve bought several of these now. I’ll do my best to give an honest review.First of all, the craftsmanship is good. The PCB is very cheap, however, and the first one I bought (the FX Audio version) had an issue with the general area of the power supply section and it caused it to short out. Be very careful when plugging the adapter in.Speaking of the adapter, go ahead and toss the included one in the trash and buy a bigger laptop style power supply. The one that comes with it seems to be underpowered and gets very hot.As far as the tubes go, the 6k4 tubes that come with the unit are not bad. They do not sound terrible and I recommend keeping them in if you’re looking for better midrange response.But if you care enough to buy a tube preamp to listen to your music with, chances are that you’ll want to hear what the 5654s are like. I’ve used a lot of different NOS vintage brands, but the GE Jan is probably the best overall sounding tube, followed by the Westinghouse “Black Hole” style tubes.If you feel adventurous and you like tinkering with radio equipment, feel free to change out the op amps inside. If you’re feeling really adventurous, change the dual op amp to two single OPA627’s. Change the plastic tube fixture to a ceramic or bakelite one.With one of my other tube preamps, I’ve changed out the generic capacitors with vintage paper in oil capacitors and the sound keeps getting better.If you’re bored enough, you can really make these sound amazing. It’s a great little entry point to tube audio and electronic tinkering.

### ⭐⭐⭐⭐ Skeptical....
*by J***3 on July 8, 2019*

Like a lot of posters, I am skeptical of these cheap mini chi-fi components but decided to give a shot. My expectations were low, which is good in the audio enhancement world, we all know how placebo effect can set in when you fall in Gear Love before it even ships! Anyway, this thing is tiny and feels a bit on the fragile side when all the cables are plugged in. No issues plugging in the tubes, so that was good. My purpose for this was purely experimental, tweaking for the fun of it, like a lot of audio nerds. I’m using this as a buffer - running a Onkyo 7030 CD player into this pre-amp, then out to my fully restored Sansui 317 integrated amp via the AUX RCA input, not the pre-outs - Speakers are Ascend Acoustic 340se mains. This way, it get tone control functions on both the tube pre-amp and the integrated amp, allowing me to shape the sound a bit more. I had to adjust the volume on both pre-amp and amp but not an issue. It was dead quite, that was the first test for me, at least I knew it didn’t introduce any detectable noise or static. I did notice more of a tightness to the bass, highs seems smoother in this early stage using the stock tubes. It’s sounds surprisingly good, and gives me the ability to fine tune bass and treble. So, yeah, it made a difference in my system, and because of that, I just ordered a set of the Russian tubes to test out. In fact, I may build a office system based off these mini pre amp/ amps, as I have an extra set of nice bookshelves speakers laying around.

### ⭐⭐⭐⭐⭐ Best tube preamp for budget HiFi Setup
*by S***O on June 19, 2020*

The media could not be loaded. Let me tell you this tube preamp is a game changer and the Suca preamp lets you really tweak the audio they way you want it to sound you can even change the tubes out I recommend going the the GE JAN5654W tubes it’s really gives you that warm crisp sound and really brings out the notes in every song you play that maybe you missed or didn’t notice before if your looking to build a hifi setup this tube preamp is a must also this preamp works great with the audio technica lp60x turntable but you have to make sure the switch on the back of the turntable is switch to line that means the built in preamp is on it’s sorta weird cause they say it’s not a preamp for turntables but it’s a tube preamp beats me but if your turntable has a built in pre amp this tube preamp box is a must
