This is a high value item. It feels solid and sounds great. It is quiet and versatile. There are 4 line level inputs, if you include the tape monitor loop, which is also handy for including a processor of some sort. The controls/features are generally of the "old school" types, offering flexibility, and are all analog in operation. One curious feature is the "low filter" which is not a turntable rumble filter; it is down about 3dB at 50hz, and 7dB at 20hz---maybe it is intended for reducing bumps and thumps when using the mic input as a PA for voice? There are separate line level outputs that are filtered to allow one to make a basic 2.1, satellites+subwoofer setup---with appropriate external power amps, of course. I took it, along with high quality power amps and nice, very revealing, speakers to our DIY audio meeting and there was much appreciation for the overall sound of the system. We were able to input a few line-level sources, and switch between them with ease. The simple analog volume control was very handy also. The "loudness" control which provides variable boost to the low end was nice to compensate for the meeting room, which tends to be a little lean with many speakers. The slim profile of the unit made it easy to integrate into my DIY portable system "rack". My PX-1 came with rack mount brackets, which were in the box, but not attached. The mono/stereo button is good for various purposes, and is seemingly rare these days. The bass/mid/treble controls are useful. I think that if I could change one thing, without making the unit more expensive to manufacture, it would be to have a bypass button for the tone controls, maybe in place of the "low filter"???----though this would make it more of a HIFI piece, and maybe a little less versatile for PA work. Customer service answered my emails within 24hours, and even consulted with engineering about technical questions. Customer service answered my emails within 24hours, and even consulted with engineering about technical questions. I was a bit astonished and quite pleased! PS: My unit came with an outdated spec sheet that lists higher distortion figures than those shown on the Amazon website. Customer service assured me to trust the figures that are posted on Amazon. My DIY-audio friends seemed to be quite happy listening to music through the PX-1 past the time the meeting was scheduled to end. This unit makes good sound.

finally got to hook this up and use it. This is one really good preamp for my system I use while working on my speaker projects. Paired up with my phone very easily and am also using it with an old multidisk CD player. Sound quality is very good and I cannot hear any noise or distortion. This is a very good product, even at the low price, it is still high quality where it counts, the sound.

I own the OSD pre 1 as well for a bedroom setup. That is also a great budget preamp. The Dynasty however has two outputs and a sub out . Which my OSD pre 1 does not. Same size same design nearly , besides the aux select , on the osd it's a knob on here its a button. I have this preamp hooked to my sansui 221 and a pair of sp30s. And the sound is fuller and deeper then when I had all my inputs attached to a small moukey mixer which had ground loop issues . And now all my inputs are clean. No hiss no pops on start up . I would recommend either one as the sound quality is superb for the price if your looking, but this dynasty one wins the battle with the multiple outputs and sub out . OSD better design a pre 2 with the same function .

I have an audiophile preamp. I am setting up another stereo system so needed to buy another preamp. I bought another used audiophile preamp online that was described as working good. It had distortion and display issues. The dishonest seller reluctantly took it back. So I started looking for a new preamp and bought the Dynasty ProAudio PX1 based on the good reviews. It sounds great with clean sound and was cheaper than the used carver. I can not tell any difference in the sound between my audiophile preamp and the Dynasty. I highly recommend it.

The media could not be loaded. I have had this preamp for over a month now. I held off on writing a review because I wanted to be sure what my ears were hearing. I have a Yamaha R-N1000a Network receiver. Great amp, but it tends to skew a little bright for my tastes and using the tone controls on it are a pain. Anyway, I couldn't get my Onkyo 6 disc CD player to the warm sound that I prefer and it sounded underwhelming. You could say that it sounded too clean if that's such a thing. So, I take a chance on this preamp because this was one of the few I could find with a optical in and tone controls (bass, mid, treble, loudness). I plugged my CD into the optical in on the Dynasty Pro Audio and used its DAC and wow... I am so impressed! I run the preamp into a dbx 15 band EQ so I am really able to shape the sound to my liking. I have also plugged my AT-LP120 XBT turntable into the Dynasty Pro preamp phono stage...and again, wow!!! Finally for flips and giggles, I plugged in my Wiim Ultra into the Dynasty Sound aux jack to see if I could tame some mids that I couldn't get under control when I had it running straight into my Yamaha. Three for three! I absolutely love this thing. The value is insane for what I paid for it. Update: 8/10/25 - Just bought a second one, this time the PX2 because I wanted to run my Onkyo CD player through the optical and still use the additional USB DAC with my Wiim Ultra. So happy with this. Wiim sounds amazing through the USB DAC and the Optical sounds makes my Onkyo crystal clear. This thing is amazing for the price. I would love if they added a remote and a larger volume knob in it’s next iteration, but aside from that I give it 10/10.
