I just don’t know what to think. These class D mini amps are always reviewed in near field and in isolation to entry level A/B amps. 1970s electronics are shooting up in price thanks to internet hype. But 2000s electronics can still be found for cheap. I’m thinking that my Creek 4240 amp is a better deal than this Topping. It’s built like a tank and sounds powerful despite its diminutive size and specs. My point is, Creek made a good small amp 2 decades ago and few people cared. I’d like to compare with this Topping amp but I don’t feel like buying more stuff.

Same question...

Hi Vlado, I didn't use EverSolo's analog outs because I don't expect that to be a good combination - it's clean and lean sound signature times two. PA7 would work best with something that has fuller tone timbre like Chord Mojo 2. Even Topping's own E70/velvet would be a better match than EverSolo.

Probably your speaker. I get a lot of base with Kef LS50.

Brio has more faty bassline, more loose sound overall with more slam but less grip. PA7 plus is more neutral, with more precision and better pinpointing. So it depends on the rest of the system and matching.... And finally your taste.

Lack of slam, punch, authority and low-end is almost certainly the power supply, and the incredibly thin lead connecting it to the amplifier. Basically, lots of volts, not much current. 200 watts @ 4 ohms is 7 amps. Put money on it, that's all the current it can deliver. My 20+ year old, 50 watt (8 ohm) integrated can kick out 20 amp peaks. Hence, it's got punch, and can fill a room with sound.

@@RacingAnt 52 volts at 6.5 amps is pretty darn good. Not sure on the impedance curve of his speakers but he doesn’t appear to be in a huge space so I’m not convinced he was running out of current

@@seanb3303 6.5 amps is only 3.25 per channel. At 3 ohms (a typical minimum impedance for an 8 ohm rated speaker), that's only 30 watts. Yes, it's a 300 watt supply, but we're not struggling with volts at this point - it's current to drive those speakers. A 30 volt, 10 amp supply would be driving 75 watts into each of the same speakers. Ok, peak power would be lower, but it would generate a more room filling sound. My old Arcam Alpha 2 was only 30 watts, but would drive speakers better than many 80 watt amplifiers, as it could deliver the current needed. Trouble is, this doesn't sell amplifiers (apart from to those that know), but huge theoretical outputs do.

@@RacingAnt it looks like he is running jeff bagby spirit wind speakers…likely lower impedance as DIY. Living room in background looks smaller…i think he’s in Yugoslavia..so maybe a 12X16ish room…I guess it would depend how loud he cranks it.

It's 4.4x7.2m (15x23ft) room with some open spaces in the back, but I'm sitting in the midfield listening arangment and I really don't crank the volume much most of the times. Spirit Winds are not particularly difficult load, not more than KEF LS50 that I also used with this amp. Not particularly easy either to be honest. That said, I recently had a 50W tube amp driving them both without much problem. It couldn't hold as firm grip on the bassline as some more powerful amps, but the sheer slam wasn't lacking. Topping PA5, SMSL A300, and AO200 MKII exhibit this same type of restrained sound character when it comes to slam and big swings, and I tried those with several more sensitive speakers that don't dip much with impedance. To cut it short, it's a character of the amp. Hegel H90 had that same character too. BTW, just a bit of trivia - Yugoslavia fell apart in 1992 when I was like 7 years old.

Fosi V3 is coming soon so I will compare them at some point.

Many class D amps have enough power for its voltage and no more headroom. ASR has measurements on this amp, it does about 200 watts at 4 ohms. I had this amp and it sounds good. I sent it back because it doesn't offer anything over my $3k amp, 😅 and I didn't need it. No issue with it or how it sounded.

​@@DearSXyeah, likely limited to around 8 amps, which means no grunt to really move a speaker cone at low frequencies, hence the lack of punch. 8 amps is 8 watts at 1 ohm. Many speakers have an effective resistance (EPDR) that's in the 1 to 2 ohm range at certain frequencies.

If it's a fully balanced design, then there's no bridging the outputs - it's effectively already bridged. Issue for slam and room filling sound isn't a lack of volts (which bridging into mono would add), it's likely a lack of current delivery. I'd bet it outputs a max of 7 or 8 amps, so will only kick out 50 to 60 watts into 1 ohm, or 7 to 8 volts, when it's kicking out around 32 volts at 8 ohms. So, no grunt to really move a real world speaker. TLdr - this 250 watt amplifier behaves like an 8 watt amplifier when driving real world speakers, unless those speakers are a really easy load.

​@@RacingAnt1 ohm loads are not "real world" speakers. Most speakers now a days are 8ohm nominal and dip to 4 ohm at certain frequency only. Why would this amp not put out enough current for the most common speakers?

@@ckamireddy you've obviously been reading different technical reviews to me. Many speakers that are labelled 8 ohms, still have an EPDR (that's the effective resistance, that takes the phase angle of the current vs voltage into account) under 2 ohms.

@@RacingAnt PA7 produces 125 watts into 8 ohms and nearly twice the power into 4 Ohms for my bookshelf speakers which need anywhere from 20-100 watts. I sleep fine at night.

@@ckamireddy I'm sure you do. My comment was a technical observation, around the reported lack of punch and room filling sound. If the amp works perfectly for you, then surely that's all that matters? Nothing is perfect in this world, and if that amplifier's advantages and compromises works for you, then that's awesome. It doesn't stop my comment from being correct.

For me it was worth it, I have SMSL AO200 MK2 and it was worth it, it is more powerful and I don't hear any noise.

​@@AdamMrozek84 how Is the sound stage ?

@@andrearossi5491 Honestly, I can't hear the difference. You can hear better instrument separation and stereo imaging. It has better dynamics. Zero pop when turning on and off and plenty of power. I have Pa7 without plus. There is no point in paying more for a slightly more power supply. In my opinion, thanks to this, it will not heat up as much as in the plus version, which will increase its reliability

I can't hear anything. it was delivered today. This amplifier sounds very good. I have an SMS ao200 mk2 and there was a lot of noise there.

@@AdamMrozek84 Thank you for your respond :))) I can hear a lot of noise out of the AO200 mkii and AO300, and I have been searching for a class d power amp to connect to my class A/B integrated amp for my main listening room. I will order the PA7 Plus and try it out.

@@dukeandappricot No problem. I have pa7 without plus. The difference between pa7 and plus is only a slightly more powerful power supply. Btw, my speakers have 92 db sensitivity

The only difference is power. I haven't tried non-plus version but Plus probably sounds a bit more dynamic and alive. Tonality and other qualities should be the same.

Tks for yr information so for PA7 plus the speaker at less how many watts tks

Memory can be a tricky thing but Atoll IN100 is doing dynamic swings better than Hegel H90. I loved it for its many qualities but even my old Cyrus 8vs2 had better kick then it. Now, H190 was a different thing but that's in another price league so I was limiting this comparison to H90 only.

I never tried SA400 so can't say.

Matching makes the magic happen. Match higher ends speakers with higher end amps. While Bata makes great shoes, u wouldn't see me wearing a Louis Vuitton with a pair of Bata shoes.

I own Topping and SMSL products for years ,No problems yet. Use them on a daliy basis ,for the money you won't find better .

bought the PA5 from HifiGO and had issues, just like so many others. It was such an awful Warranty experience, worst ever! Topping PTSD sufferer now 😢

Don’t expect too much quality or reliability, Topping still needs a few years to prove themselves. So far, not a great track record, mainly talking about their amps. But I had an issue with a DAC they messed up too. If you are in North America, buy from Apos.

I second Apos. @@tallpaull9367

I've had topping HP and SMSL DAC, 3 months no issues, let's see in a year

PA7+ but still I would not describe it as rich in timbre.

@@iiWiReviewsthanks for the quick reply! I am digging deep in your reviews because I want to upgrade my electronics after getting a new pair of R3 Meta. Currently they are running with Modi+ and Aiyima A07 + sparkos opamps. I liked your comments regarding Smsl d300 and Brio/A300. I enjoy a rich and natural midrange as I am spoiled for using Senns Hd650 for over a decade and would like to get similar sound from speakers. Any suggestions? I will continue to watch your reviews PS: Brio could be great but i’m concerned it doesn’t have the power to drive the R3 meta with authority and full woofer control

@@iiWiReviewsI forgot to mention that i’m considering iFi Zen One Signature as well. I have the Zen DAC V1 and tried in my main system, and really liked its tone, which is more organic and natural than Modi+, but it lacks separation, don’t have a wide soundstage, it’s more congested and lacks the deep bass and punch from the Modi+. I wonder if the better zen one sig would maintain the natural sound but solve these issues. could pair well with the neutral pa7+…

You pairede pa7 with kef? How it sounds?​@@mxjoaoo

I wanted to say power output or power delivery but got tangled with words... Speaking English while filming and trying to be concise is not easy for me because I consume a lot of it but rarely get a chance to practice speaking. Proper grammar is usually the first to go but I mix phrases sometimes too.

@@iiWiReviews As a natural English speaker, I find your articulation and pronunciation exemplary. Over the years, a lot of years, I’ve spent way too much money on HiFi gear. You and other reviewers how much more bang for the buck you can get these days, and then some when you figure in inflation.

Assuming current limiting on the output stages doesn't cripple it... Big current requires big output transistors equals big $$$$. I'd guess the power supply can only handle 8 amps, and the output stage maybe 10.

@@RacingAnt The power supply is 52v 6.5 amps. The PA7 plus reportedly has dual tpa3255 amp chips. A single one can be powered with 48v 10 amps.

@@D1N02 yeah, beefier PSU will definitely help if it's only 6.5amps. If that's shared between the 2 channels, then it's really going to struggle in real world situations. No surprise there's no punch or slam 😞 Decent stereo class D, 250 watt amplifiers pack 1,200 watt+ PSUs, not 300 watts. Yes, the one I'm thinking of is $1200, but it's likely worth the price. I don't really get the specs of this product. Who needs 250 watts in a desktop amp? 30 (with the current delivery to truly back that up) would be more than enough. But it can't drive speakers in a large space either. 🤷

In this video I presented only the power rating at 1% THD. It's higher at 10% and you can find it in the spec sheet... but I didn't include that one.

I think so too, it also has a remote control, display and tone controls.

Yes, no other way to cram 100+ Watts in such compact device.

U knew D class...power efficientcy. If u liked D..then AGD is world best..yup audience. Peace3
