OSD AudioPre-1 High Definition Preamplifier – Multi Source Select Phono Ready

This preamp sounds great! It boosts the lows, mids and highs pretty well. I barely push the levels on it and it sounds fantastic! For the price it’s worth buying.

I was building a component audio system and needed a way to manage my inputs. I wanted a clean design as well as low distortion. Essentially I wanted a system that would manage my inputs with out introducing any hum or noise. I just needed it to be there. I read some reviews that indicated the introduction of hum, indicating a lack of grounding. I do not experience this. The pre-amp is quiet and simply does what I need it to do.I have a Sangean HDT-20 HD Radio/FM Stereo/AM Component Tuner, Refurbished Technics SL-Q5 Linear Tracking Turntable, Douk Audio T4 PRO Vacuum Tube Phono Preamp and Audio Source AMP310VS Amp attached. I connected the Turn Table to the Aux. 1 input instead of the included Phono input, as I wanted a tube based Turn Table Pre-Amp for that "Warm Sound". Overall, I am very pleased with the system I built.

Just set this up. First off, it shipped timely, came well packed and arrived in perfect condition. Seller deserves 5 stars.Now for performance. (This is being used with a solid state Kenwood M1 -100 watt per channel power amp running through Klipsch Icon KB-15 bookshelf speakers hooked to a Klipsch sub-woofer, just for reference)All inputs function properly. All controls function properly. Sound is fine, nothing exceptional, but fully satisfactory for a preamp of this price. Separation is fine, depth is fine, tone is fine, again nothing exceptional, but very satisfactory. So for basic performance everything is doing what it should and how it should.The fine details:As mentioned in othe reviews, the volume knob is extremely touchy. With my 100 watt amplifier I don’t turn it up past 1/3 of total volume, and it is detented so getting the volume where you want it is difficult. ( solved this by buying a small in line volume knob to run between this pre-amp and the power amp. Cost about $12.00 on Amazon. Easy fix. Thanks to other reviewers for that heads up so I was prepared with my fix when I received this pre-amp). There is some low level cross talk from other inputs. ( just make sure that you turn off the other devices you have connected to this pre-amp and this is eliminated. In other words, even if you have the input for your CD player not selected, if you then select the input for your tuner, there will be a very slight sound from the CD player still coming through. Solution is don’t play you CD player while listening to your tuner, and don’t leave the tuner on when listening to the CD player, etc. A bit inconvenient, but not a deal breaker. Again thanks to previous reviews for that heads up.So, all in all, this item is exactly what I expected. It is a basic fully functional pre-amplifier that functions as it should and as I expected. For the money, it can’t be beat ( not to mention that there is no other pre-amplifier even made or sold in this price range). So if you are only looking for exactly what this is, and you don’t want to pay a minimum of $1000.00 for the next least expensive pre-amp out there, this is your next pre-amp. The only one made, the only one sold and the only one available to function as an acceptable pre-amp for your stereo setup. Hope this helps others in the same quandary that I was in when considering this purchase.

This is a quality built product. I have to air my grievances about having the rack ends on the product. I will not remove a star for that aesthetic because I'm sure people use it in the rack. Anyways I was having trouble with my mixer to my avr . Now no issues. Great loud signal for all my sources. Strong metal casing and knows that I now use before any other knows. These are now my main knobs. OSD is a company I trust now . This is a superior product in its class for the price point . And anyone needing a signal boost that's clean and powerful for under 200. Can't be beat .

It was working before I knew it, I connected it and heard subtones in the music that I never heard before, not a lot of volume increase but a fullness increase; an unexpectedly presence in cds and especially photographs. And enough power for two more speakers.

Good quality sound

Very good preamp at a great price.

I really just picked this up because my receiver has no preouts, so I bring my signal straight from my pc to this preamp via the 3.5mm aux to rca adapter cable....but as it turns out, I find the bass, mid, treble, and loudness adjustment dials on this unit to be so effective and handy that I'm really not making tuning adjustment anywhere else.....the best part, though, is that I can set all of my volume/gain levels on my amps (running 3 right now) and on the pc where the signal comes from when i turn everything on, and from then on I only use the single volume dial on this preamp to adjust the volume up or down for everything....sounds like a small thing to some, but I listen to a lot of music and it gets to be a big pain if you don't have an easy way to make volume/gain adjustments on 3 frequency ranges with 2 channels per range...everything I need for the most part is right there on this preamp...I love it and it was more than affordable compared to pretty much anything else you'll ever buy for your audio system....any time you can spend $100 or less and it makes such a substantial change to how you can operate your many electronic wares, it is a huge win as far as I'm concerned...this unit had great reviews...and that is why i read the reviews religiously on Amazon...get one of these units....totally worth it!
