I guess this is the place for this. I'm sort of in a search for a budget (as in cheap) stereo amp/tuner to use with an older pair of Sony bookcase speakers that I've got sitting around. Should be able to accept input from cd player/phone/tablet/Bluetooth. Don't need anything elaborate - just would like to occasionally sit in my recliner and listen to the gazillion Mp3 and wav files I've collected over the years. Would rather hear speakers than headphones or ear buds. I found a little Pyle unit on Amazon that looks like it would do the job but the reviews were not encouraging. Any suggestions? Budget probably <$100.

I reviewed class D amplifiers for audiophilestyle.com a while back (link). While doing my research, I bought a Pyle PDA29-BU6. It's $50 now (it was $33 when I wrote the article!) and does everything you want it to do and a lot more. I loved it so much I kept it (I usually sell my test stuff as soon as the aritcle is written). It's an amazing little device that sounds fantastic and has ample power. I took it apart, and it's also amazingly well made - especially for the price. I've even used it as a stereo guitar amp through my two Toob Metros with my Zoom MB60 stereo effects pedal - and it was amazing! I'd ignore those reviews and give it a shot.
[For reference, my main listening system is a Thorens TD125 / SME t'table, Parasound preamp, a variety of DACs (SMSL, iFi, Emotiva), a Prima Luna tube power amp, and a pair of Focal tower speakers.]

The amplifier seems quite robust. I've even gigged with it through a pair of Toob Metros running in stereo (driven by the stereo outputs from my Roland GR20 synth), just to see how it handled the task - and it was stellar! It feels pretty solid, and as I said in my first post about it, the insides are very well organized and assembled. It's hard to believe it cost me $33 new and is still only $50.
It's not McIntosh, but it does the job!

I decided to buy a pyle. I going to use it until I replace the SD powerstage. Now I have to figure out how to get the cables. Typical I just grab speaker cable.
I think I have it all figured out. Flex pin are just screw in… so I think I can take a couple of my speaker cable and get some flex pin thing and just unhook one end from the ts and hook up the flex pin.Last edited by st.bede; 05-02-2023 at 02:00 PM.

I have it …. EDITED as not to confuse people. I was doing things wrong.
(See below for more information from someone who knows how to do things.)Last edited by st.bede; 05-08-2023 at 03:01 PM.

The Flex Locks are a tight fit into the push-lock terminals on the Pyle - I had to crush and fold them axially with a flat pliers to make them small enough. You can also simply tin the tips on the amplifier end of the wires with solder.

It sounds remarkably good … guitar, into jhs clover, clover into pyle. It is even taking a ts9-clover-pyle really well. It is completely usable.
-
I just found and bought a used voodoo lab giggity, (at a good price) so I can have a second small pedal pre-amp, for stereo.
-
I know I am crazy… and sometimes I write before I have thought things out…
I have the pyle running mono. It is not that loud. Can I bridge it?
(I am assuming if I run it in stereo (it should be louder… but I am waiting on a second preamp pedal).

A quick test: try other speakers. Speaker efficiency can make a huge difference.
-
Thank you both.
-
Fyi… I am presently running out of the JHS Clover into the L aux. When I have the giggity I will run out of that into the R aux. (Assuming that the giggity is a real pre-amp, not a pedal that says pre-amp but is really just an od).

So I make sure there’s a speaker plugged in before I plug my Microblock in to a power outlet.
I once fried an amp because one conductor in a speaker wire broke at the plug. It was pretty dramatic!

Thanks I did not know that.

I did blow up a computer once. I was so used taking stuff out and putting stuff in, that I was not paying attention, and while putting in a new drive, I did not line up the connector correctly. Puff and gone.
I just thought home stereo would be different… why … not really sure… lack of thinking.
As always: Thank you.

I have a stereo amp, a Dayton Audio product, specs say it's Class D, that can be bridged, and can also drive two sets of speakers. Bridging is possible, just not often done, probably because there isn't much of a market for it.

Full bridged is a differential amp whose output voltage is generated between two hot leads and is independent of ground, similar to a balanced output in other amp classes. A half bridged circuit has a single output lead and the voltage is generated relative to ground (like an unbalanced output in other classes). I have to do some more reading to find out if / how this relates to the ability to bridge a stereo output to mono. Full bridged class D amps have twice the components of half bridged units, but they make more power from the same supply.
I also checked the entire ICE line (the gold standard for class D modules) and found that only 3 of their 30 or so models are bridgeable (125ASX2, 250ASX2, 80AM2).

For affordable class D amps I recommend you check Audiosciencereview.com for serious, professional, reliable reviews.
I have two class D amps they reviewed that are fantastic, if you don't need a ton of power - not just for the price, but you get true uncompromised high fidelity. They surpassed two brand-name amps that I had (Marantz and Teac). They are the Topping PA3s and the Loxjie A30. I run the Topping with a separate DAC and the A30 with a streamer. There are a few even cheaper alternatives with good measurements on ASR.
anyone selling an ibanez pm120?
