Product Details

Topping TP20-MK2 TA2020 Class T Digital Mini Amplifier 25WPC

Topping TP20-MK2 TA2020 Class T Digital Mini Amplifier 25WPC
Topping TP20-MK2 TA2020 Class T Digital Mini Amplifier 25WPC is rated 4.5385 out of 5 by 13.
Rated 5 out of 5 by from You won't find better soundI have been using a s.e.t tube amp for the last year. I think it's sound is much better than most amps. I had a lepai amp I played around with and the sound from it was amazing. But I could not live with looks. The tripath 2020 is a special chip. It is not lacking in any details from the lowest lows to the highest highs, It is as good as my set amp amp uses a fraction of the power.Then I got this Topping , it has the highest quality parts you are likely to find in any consumer product. This is more like something a diy guy would have after building it his way. The only caveat is the same with my set amp. Low watts. Do NOT equate better sound with more watts. Speakers are getting less efficient than they used to be. You might want 90db @1 watt or better if you want to fill a room with sound.The blue light is dimmed down(thank you) and the whole amp looks and is first class. A solid aluminum knob. Dale resisters and a Alps pot. I would call this a real bargain and an amp that will sound as good as any amp in a blind test. I use mine with a phono preamp. Many modern devices like a ipod do not have enough output to let this amp sound it's best, and that is true with most amps.

Rated 4 out of 5 by from good valuePurchased this on sale from PE for an exercise area as I needed an amp that was fairly small and could drive 4 ohm speakers. As noted by others the power supply included is good and parts used surrounding the Tripath chip are very good . The slim banana plugs from PE that retain speaker wire with a small screw work well with this amp as the speaker posts are very close together. Overall the sound is definitely improved by using the Bravo V2 headphone/pre unit also on sale at PE. You'll have to upgrade the Bravo's tube to at least a JJ 12AU7 but it is worth it. IMHO ,without the Bravo tube preamp as front, the Topping is good but not great. Still a good value though. If your amp slides around on a surface you can use poster putty or blue tack to hold it down. I use that stuff to hold the Lepai 2020 that powers our TV speakers in place since it is so light

Rated 4 out of 5 by from Amazing sound quality for the price.I purchased the TP20 for use in a bedroom system, It's powering an old pair of Infinity Interlude IL-10 speakers from a harman/kardon dvd47 source. While the 2 x 13 watt @ 8 ohm rating may seem low, I'm able to achieve normal listening volume in a 12' x 16' room with the volume control at the 9 o'clock position. This amp pairs very well with my speakers so the lack of tone controls on the unit is not an issue for me.Out of the box DC offset measured -2 mV on the left and 11 mV on the right. After approximately 12 hours use it had shifted to 8 mV left and 32 mV right. After opening the unit and adjusting back to zero the amp has held fairly steady, now measuring 1 mV left and 5 mV right after an additional 40 hours of use.One more quick note. Although this amp is built very well, it is very light and moving the power switch up into the off position requires holding the unit down.

Rated 5 out of 5 by from Mini Size yet Huge PerformanceI was originally intrigued with this newer technology- and so took the plunge-and glad I did. The audio reproduction is terrific, and find I no longer need a tone (treble, bass) control to fuss with. The PARTS EXPRESS Tech felt that my desire to use a pair of 4 ohm British made book shelf speakers would be OK with the Topping Model- discouraging me from considering another similar Class T amp also available from PE- and glad to report he was correct in his assessment. I had already added a 100watt sub-woofer featuring a built-in Class D amp to enhance the low-end- and my resulting sound output is crystal clear with virtually no signs of distortion what-so-ever. When the wife forgets to turn off the Topping even if for days, I am not at all concerned unlike the old days of tube technology trying to heat my living room on a cold winter's day.

Rated 5 out of 5 by from Excellent Hi Fi ampI'm using a pair of this small amps as a mid and high amps on a 3 way multi-amp system. The sound is open and articulate. I discover details on old recordings I was unaware. The sound is clean, distortion free and very warm. Highly recommended.

Rated 5 out of 5 by from No better souding amp of its size/cost PERIOD!This amp has a transparency and sound stage that is awesome. I'm using it with a WDTV live $100(with WDLXTV software) optical out into a poppulse DAC 707 that was $130 and a pair of 17 year old N.E.A.R. 10M 4" two ways I paid $250 back in the day. Talk about low budget "high end" audio. : ) The amp is super quiet and the silence in recordings sounds "black" if that makes any sense. Won't rock the house but for normal listening levels does the job nicely. I haven't heard the TP21 but may consider one for the headphone output. Overall, very, very happy with this product. Everyone should own one of these.

Topping TP20-MK2 TA2020 Class T Digital Mini Amplifier 25WPC

I'd like to run this off a 12V marine electrical system. The rear-plate says 12-14v. If i'm delivering say 11.6V to the amp after voltage drop, etc, will the amplifier work OK? 

Asked by: aa123
I am sorry, using this amplifier with any other supply than the one from the manufacturer would void the warranty. We would not recommend it for that application.

I am thinking about purchasing and hardwiring this into a 12v power supply. I really do not want to cut apart the cord that comes with the ac adapter. What are the specs on the power plug in the back of the amp (size, polarity, etc)? Thanks in advance.

Asked by: superchris15
This amp uses a 2.1mm x 5.5mm DC jack that is center positive.

Could this amp be paired with the BOSS AVA1202 7-Band Preamp Equalizer in order to allow for some ability to adjust sound parameters?  I'm looking for a nice little amp for my son to use for iphone mp3 play back etc.    

Asked by: roger153
Yes this will work with any line level type equalizer.

If I was to buy this and play it here back in Norway, I would have to get a new power supply for 220v?

Asked by: andores
The included power supply handles 100-220VAC input so you would not need a different power supply.

Work on 12 volt car and marine battery safely? no alternator or car just a battery be itself used at the camping just affraid if it will not work with 11volt at low volume?

Asked by: mrbonami2
The amplifier will work just fine from a 12V automotive or marine battery. I ran a different Class T amplifier for 7 hours straight on a 12V/5aH motorcycle battery. Pretty good.
