Any way you slice it, $400 for this soundbar with Android TV built-in is a terrible deal.

My biggest problem with this soundbar is that you will be relying on JBL for software updates. This is a company with zero track record for software development and support. Until they can prove they are competent at this, it is a nonstarter for me.

The second thing is that the price simply does not justify the convenience of having an Android TV box built into the soundbar. If it was $100-200, I would understand. But at $400, the competition and alternatives are way too fierce.

If I am being generous, I would say this soundbar is on par with the Yamaha YAS-108. I seriously doubt it though. I'll give them the benefit though. This is a $200 soundbar.
A Mi Box S is $60. This bring the total value of having two separate items to $260. Is it really worth the $140 price difference to have them built into a single item?

Another alternative for $400 would be to start a proper home stereo audio setup. Once again, $60 for a Mi Box and $340 for audio equipment. You can buy a cheap amp, a couple of bookshelf speakers, and a subwoofer for that price. That would be the beginning of your very own home theater setup:

• $34 Class D Stereo Mini Amp (You can actually get a much better amp and still be well within budget)
  
  
• $110 Stereo Bookshelf Speakers and Speaker Wire
  
  
• $120 12-inch Powered Subwoofer
  
  Ultimately, for less than $400 you can either get a much better soundbar or a beginner audiophile setup and still get an Android TV box.

Micca MB42X, Dayton B652 Air, Pioneer BS22 (just over budget), or Dayton MK402 paired with one of these is about the best youll do ~$100 new. I would look at used speakers before making any purchase though.

I recently upgraded from an LP60 to a LP1240 (secondhand) and I've been seriously underwhelmed and am having problems.

The LP60 sounded crisper with cleaner sound which shouldn't be the case for a much more expensive table with a cartridge costing more than the previous table all together.

The 1240 wasn't nearly loud enough so I had to add a preamp, I know there is a built in one but after trying every possible Line/phono config it still was't giving me the volume the LP60 had.

Also I am getting a loud hum which I can't seam to figure out. I attracted a ground wire from the turntable to the preamp which reduced hum but is still prevalent. I'm almost positive this hum is stemming from the turntable itself as when I used the LP60 with the amp there was no hum whatsoever and the hum is still there when the preamp isn't connected.

Would this t-amp work for this setup.


So I get speaker wires to connect it to the t-amp and then connect that to the TV?


Which and how many of the red and black outputs do I use and or which ones?


I'm sorry for all the questions as I am new to setting up speakers.

Haven't owned one personally but hear from many it is the original Tripath 2020 board.. i do want to order one to confirm and keep around.. Wish I knew how to mod them like some, I remember companies selling modded Lepais for $100-200 when they were $20-25 on Amazonlol

In my garage, I run a chromecast hooked up to this guy running a pair of 8" speakers from the 80s. :https://www.amazon.com/gp/product/B077Z7DBRT It's 20w and powers them just fine for the whole 2-car garage. I'm not recommending that for high volume, but it does the job. A used receiver would work really well too, they're just much larger.

​

You can get a pretty simple RCA pot volume control knob on amazon that you could use for the sub. https://www.amazon.com/PAC-LC-1-Remote-Amplifier-Controller/dp/B0002J226O/

Exactly. A proper stereo is the solution here. Use a decent amp and speakers for the audio and pair it with an Echo Dot to control it, using the line out jack on the Dot to connect it to the amp.

If /u/Treas0n is looking for a good budget option, I'd highly recommend the Lepai amp + Dayton speaker setup. This setup is the go-to budget kit on /r/audiophile and would be plenty loud with really good sound quality. It's about $90 for the whole kit (+$30-$50 for an Echo Dot):

If the OP wants even bigger sound then add a powered sub for $100 more (you may want to double up on your 16ga speaker wire for connecting the subwoofer between the stereo speakers and the amp)

The Micca speakers has been around for a few years and there hasnt really been any competitors in that price range and size. The Dayton Audio subwoofers, no matter wich you pick, is good for its price. You can get better speakers if you go up in size or price.


The only tricky bit is to pick an amplifier. You mentioned in a different post that you saw a Kinter amplifier similar of the Lepai LP2020TI.


That amplifier actually uses the Tripath TA2020 amplifier chip, wich is a good chip. Wich is also why it costs a bit more. The Lepai uses the Texas Instruments TPA3118, while a good chip, is not quite as good as the TA2020


https://www.amazon.com/Kinter-K2020A-ORIGINAL-TA2020-020-Amplifier/dp/B077Z7DBRT

If you just want an amp, without AM/FM - The Kinter 2020A+ is a clone of the original Tripath chip Lepai 2020 that became legendary a few years ago (and is not in production anymore) It also has a much better power supply. The newer Lepai units use a Texas Instruments chip.

Check youtube for some of the budget audiophile setup vids. You can hear rich, crisp tunes for $100.

Personally, I'd check out letgo, marketplace, craigslist for the best brand you can find in your budget - regardless of age. I'm satisfied with an old Denon/JBL setup that was about $60 total. Bluetooth to Phono or RCA adapters are cheap, and there are really decent phono pre-amps out there for under $35, if that's part of your agenda.

Subwoofers are amazing, even at low volume.

It's an amplifier.

I had to swap the faceplate upside down which was difficult but worked okay. I had to shave a few mm off the PCB with a coping saw but it fits and it works. Not all the screws line up but it's held together well.

Not looking for anything elaborate, just for my PC uses(Music,games mainly).

I don't know much about anything, but multiple places online said this one is better. I got it and have no complaints... but again, don't take my word for it.

I agree, you'll likely have better luck in a more home audio forum, however I do have some advice.

Your best bet would probably be to shop around at yard sales/flea markets and look for a used home theater stereo receiver. For the most part (if they support 5.1 surround), you'll get the two amplified speaker outs that you need, plus a subwoofer pre-amp out (and the 3 additional speaker outs if you decide to expand later). I've picked up many of these over the years and they usually run from free to $40.

​

If you want this faster, you can take a look at the Mini Class D "tripath" amplifiers for sale on Amazon, like this one. Run the speaker outs from the amplifier into the "speaker level in" ports on the sub. Then run the "speaker level out" ports to the speakers.

I've got an Audio Technica LP120 and a pair of Acoustic Research AR-8 bxi (6.5" cone, 1" tweeter), all of which I received as a gift. As far as I can tell, to get up and running I need an amp and a powered sub. Application is a roughly 20'x20' living room.

2 Questions:
What size sub should I be looking at? Is there a rule of thumb for sub diameter in relation to my 6.5" speakers?

How many watts should I look for in an amp for my application? Kinter K2020A+? Or is there something similar I should look at that can produce more watts?

I see what you mean about the cost. For that much money I could buy two used AVR-1610s and power the surround backs with one for each channel. LOL

Any thoughts on something like this? (Other than what you've already said about class T amps.)

If you are looking for budget alternatives... This tripath amp has cult following:

2. $33 for one with a true Tripath chip - what made this amp type famous, and what the lepai’s once had. Hard to find. I have two of these, one pushing large towers and it does well. Very loud at 50% volume on the amp knob. They frequently go out of stock and will probably eventually run out. Also has a true 12V 5A power supply so you’re getting the wattage indicated.

   All include a power supply. It’s possible to pick one that has Bluetooth, if desired. Probably $35 for one with Bluetooth. Let me know if you want me to find one of those.
   
   Edit; you’ll find these for $9 but they won’t have a power supply. However, if you keep a box of old cables and power supplies do check it - you would likely have a 12V supply from something else. Check polarity to be sure, and make sure it’s 12V and >3A if not 5amp.

The real Lepai doesn't use the tripath chip anymore. The Kinter 2020A+ does (and has a more robust 5A power supply). Lepai uses TI chips now.

Fantastic guide. A very good read. I was very curious about your recommendations for budget speaker/amp combo and I ended up going down an Amazon review rabbit hole. There are loads of comments on how the Lepy/Lepai amp you mentioned has been changed and is now being sold with inferior parts to what it had originally. No sure if you're aware of this. Something about a tripath amplifier? In any case I found a similar device which still reportedly has this "Tripath amplifier" which is now missing from the Lepy/Lepai Kinter K2020A+

Kinter K2020A+ Amp

Get this actual Tripath one instead. The power supply is already upgraded to 12V 5A as well.

​

I enjoyed the class "T" Kinter amps the most. Its amazing how nice it sounds for under 40 bucks. The SMSLs definitely look cleaner, but honestly I doubt they sound better.

@ sharkamino I'm probably going with https://www.amazon.com/Kinter-K2020A-Limited-Edition-Original-Tripath-TA2020-020-Class-T-Hi-Fi-Audio-Mini-Amplifier-with-12V-5A-Power-Supply-Black/dp/B077Z7DBRT/ref=cm_cr_dp_d_rvw_txt?ie=UTF8#customerReviews since it has Bass and Treble Control, with Dayton 1000.

@ SmittyJonz I can push a little more if I can get better speaker than MK402X, I saw another replay from you to another user on this sub, you suggested Micca MB42X, Dayton B652 Air and Pioneer SpBS22 , if you think B652 or BS22 does better than MB42X then I will go for those instead. btw the guy who didnt like MB42X didnt have a subwoofer so probably thats why he was dispointed.

Btw I found above DAC which I linked, it has control over Bass and Treble, do you think its a better choice than SMSL SA50 50Wx2?

It'll work but the Kinter tripath 2020will probably work much better

Edit: those speakers punch above their price. I've a pair outside through all seasons that are still going strong.

Didn't change the monitor, used this LCD board, wired built in speaker to kinter amp flipped power switch on control panel and wired to PI header to turn on. Waiting on skin from Arcade Graphix. Went with sanwa joysticks and Happ buttons fromDIY RetroArcade. Plays nice. I'll post pics when I get home

How big an amp(and how many) are you looking for?

What's your budget?

What sort of speakers are you trying to drive?

Where will they be located?

And again, what's your budget?

Small

Medium

Large

Any of those three will fit the bill depending mostly on your answers to the above questions.
