Question: Got a 15 x 11 living room in Condo. Speakers are Polk towers T11s. Will this sound better than my old Sony STR DE 185?
Document: The NAD 7200pe has better head room. But then, it takes up too much space on my computer counter, and who needs old-school big electronics anymore?Finally, the Lepai has a slight turn-on "pop" but none from the Topping. Also with no input, I can turn the Topping all the way loud with no sound from the volume control, indicating fairly good quality.
I needed a small amp to hook to my Mac Mini, and the Lepai 2020+ filled the bill. For its size and the price, I was very happy with sound I got from the Lepai when I hooked them up to a pair Polk 5JR speakers. Those speakers and the Lepai are all you need for a 12x15 bedroom. For $20 it's an amazing little amp. However, when I hooked the Lepai up to a pair of Polk Monitor 30's the sound lost nearly all its depth.
Driving 20-year-old KEF C75s, this amp sounds great at medium volume. The KEF's are quite sensitive, and go quite deep, but don't play especially loud; I think the Topping is a great match. No noise or hum at all, plays without coloration, and can easily fill my large living room at moderate volume. I like it!
The unit is quite deep considering its otherwise diminutive profile, and considering all the wires and cables that will be connected, keep in mind that it needs a nice deep installation area. It measures 5" deep, but do yourself a favor and budget 8" - 10" of depth on the shelf for this.Sound QualityMy main zone has all Polk: 2 x RTI A3, 1 x CSI A4 and 1 x PSW111.
I am using this to drive a pair of Paradigm Atom V3's that I got off of Ebay. The sound has been nothing short of spectacular compared to my old computer speakers, and in fact either beats my HD280Pro Sennheisers, or gives them a run for their money. I'm really amazed at how well this thing drives these speakers, and would easily suggest this to anyone that wanted to do the same. Just make sure to pick up a 3.5mm Male to RCA cable. I got the Mediabridge myself.
I love the fact that neither my DAC nor this amp have circuitry to modify the sound (other than to adjust the gain in the amp); many times, less is more. I almost passed on purchasing this amp because Polk specifies a minimum power requirement of 20W for most of their speakers. Perhaps they're being cautious so as not to disappoint a user with a large listening room, speakers positioned at a much greater distance, and who likes to listen at far higher volume than I do.
I bought this TP22 to replace a Lepai TA2020c used as a computer desktop amp. The TP22 gave me a step up in sound quality, especially the bass, where the same old speakers now sound noticeably tighter and deeper. This could be due to the extra power the TP22 has over the Lepai, or the inherent great sound of the Tripath TK2050 chips, or the better quality components Topping uses.Visually it's good-looking, with a thick aluminum face plate and extruded aluminum case.
Don't let that number deter your purchase because 2 x 12 watts RMS, 20-20k at .01% THD + noise at 8 ohms might be the rating I'd give it as a guess, but all manufacturers deceive so you don't know what any other amp is to compare it with or how many watts you usually use and clean power is deceptively quiet sounding (2 x 200 watts can sound qui...not loud) until you leave the room and hear it.
I realize most don't work with frequency adjustable x-overs in multi amp systems like I have for decades, so I'm just trying to help.The room it's in is 16 x 16 x 10 and cool with a concrete floor and little furniture to soak up highs so I use Breakaway to warm it up but on axis sound is a little harsh when trying to fill the room with music (your room is critical, read on the subject and make any possible improvements).
I would not use it as a "main" amplifier for the living room, but if you want a relatively inexpensive, uncomplicated, and compact way to power some bookshelves without haggling too much over optimum sound, this is just the ticket.
Answer: Probably not.  The Tp22 will likely not have enough power for those speakers in that size room.  The amp's 30 W ratting is misleading.  Relative to true Hi-fi specs it only has about 15 real usable Watts.  Youy speakers have a minimum power recommendation of 30Watts.  Unless you listen at low levels it would be too stressed to sound it's best.  I use mine to power desktop speakers at low levels at close distances and it works great in that role.
