Product Details

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

The Topping TP20-Mark 2 mini amplifier is designed around the sought after Tripath TA2020 amplifier chip, making it extremely efficient while maintaining audiophile-grade, tube-like sound quality; additionally, the TP20-Mark 2 provides a wider soundstage and deeper bass.

This amplifier is ideal for driving small to large-sized loudspeakers, and its size makes it a perfect solution for desktop systems—the TP20-Mark 2 has enough output to rival many large stereo receivers. Machined aluminum construction adds a touch of class and the amp is manufactured using only the highest quality components, including Elna capacitors, Dale resistors, and ALPS volume controls.

Topping TP20-MK2 TA2020 Class T Digital Mini Amplifier 25WPC
Topping TP20-MK2 TA2020 Class T Digital Mini Amplifier 25WPC is rated 4.5 out of 5 by 12.
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.

Rated 4 out of 5 by from Great little ampThis is a great little amp. I have it hooked up to an Apple Airport Express and good-quality bookshelf speakers ($300/pair, 15-150W, 8 Ohms), and I exclusively use Airplay from my iPhone to play music and podcasts to it in my bedroom. It's small enough that I have it tucked in my nightstand, and with the Airport under the bed, I've got tunes in the bedroom without any noticeable stereo equipment - works great! One thing I really like is that, at least with my setup, there's no white noise hiss from neither the device or my speakers when it's on and music isn't playing... it's virtually silent. It appears to have only modest power, but it's crisp and clean, and perfect for conversational/casual listening, e.g. "typical" listening for most people in most situations. If you're looking to crank this thing up to a level where you'd have to really shout over the music to be heard, you might find it disappointing (this is all based on my setup as described - I've never tested it with other equipment).

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.

Can I run this amp directly off a 12v battery?

I am thinking of using this lovely little amp to power bookshelf speakers in an off grid cabin. I have a 12V battery system there; no issues with alternator power spikes/other devices making noise.So given that the power supply is 12V, I am thinking I can just plug this unit right into my 12V dc battery to power. (I am using 12V 9Ah UPS batteries there.)Anyone foresee any issues with this?
Asked by: Off Grid Cabin Guy
Yes this will work fine with any 12-14 VDC power source.

What's the power output at 1% THD?

I am surprised that power output at 1% THD is not listed. 1% THD is normally the standard for reporting power output of amlifiers. The 10% THD power is kind of useless (e.g. distortion is already so loud that your ears are hurting).
Asked by: Pepelats
THD refers to harmonic distortion not clipping. 10% clipping distortion would hurt the ears. Every manufacturer has different ways of listing specs. I know it's frustrating, but sometimes we have to read between the lines. In this case, the customer reviews are outstanding. First impressions are usually correct, but most people review in the afterglow of a new toy. I do. And when I don't like something I let em' know. This is a good amp. Besides, PE has a great return policy.
