It's pretty apparent that you didn't even try it in bridged mono mode before making the statement that it won't work speakers with lower than 8 ohm load. ASR tested the amp in that mode with 4 ohms load (!) with it putting out 200W of power and the internal shutdown circuitry didn't even get triggered.
Pinpoint imaging accuracy is probably helped by those luscious KEF. LA90 a new reference amp. But no headroom for power crests of well recorded high dynamic range music when using the low sensitive speakers that are becoming standard today when listening in large rooms. I expect absolutely superb results "mid field" in smaller places with the right speakers.
Shame about that external power supply. I really prefer an internal unit. I'd love to move my LS50 into the bedroom (after upgrading my living room). Super happy with the performance of my AHB2, wouldn't mind having something similarly clean. If they did a slightly more powerful unit with an internal supply, I'd be sold.
I see an external power supply as a potential big plus actually. In this case, the default is it's weakest link imo but one that can be replaced with a beefier high current SMPS. The result would be something I'd be very curious to hear and expect to address some if not most of the reviewer's observed cons.
@@sonusancti I could see me changing my opinion if they had a really high quality external power supply that was stackable with the LA90 (similar to some of the holo audio stacks). Definitely not a power brick, though.
@@nmnate The brick is clearly intended to meet their business objectives but it's easily upgradeable via DIY. This is what makes this hobby so much fun, for me at least. I get to discover ways to elevate performance on my own. Cheers!
Probably the Benchmark was the inspiration. Looks nice and clean, but not surprised about the lack of base. Some companies ar good for speakers, others for headphones, Topping is clearly second category.
Thanks for your reviews, I think I'll stick with my Pa5, I don't think there is much difference in sound quality versus the difference in cost, also the Pa5 has better bass control, the Pa5 is like a sleeper car.
Is it possible that is an amplifier for a desktop set, with the other 90-series electronics ? So DAC, headphone amp and speaker amp for a pair of monitor or near field speakers ? In that view the power output shuld be adeguate for the work. What do you think ?
For near field listening, LA90 is absolutely fantastic and would never run out of breath. You can form a beautiful stack too (D90 + A90D + LA90). I stay 3 meters from my speakers and I need more power for a similar SPL vs near field
I have this amp, plenty of bass. Super wide soundstage, but that's all to do with speakers ! If power is not of concern, this amp is fantastic. It's flat and has superb dynamics. Noise floor is non existent. They are going to make a more powerful one next year. State of the art.
I have a switching mode power supply in the AHB2 as well (it's inside the unit), but it never lacked grunt or bass extension. I believe power output is the limiting factor here
How is the reliability? I ask because a few years ago I bought a Topping TP60 class-D amp. Had great reviews. Loved the sound but after a couple months, it would blow its fuse every time I turned it on. Would dim the lights in my room when I turned it on, drawing way too much current. Tried all sorts of fuses. To no avail. And just out of warranty. Ended up with a useless heavy brick. Unbelievable that Topping would use a fuse these days. So I went with and old used Teac AH500. Small, reliable, heavy beast.
Dude id advise against getting any Chinese audio company components. Ive had a drawer full of them that just broke down with in a few weeks/months. They start out really good and one day just wont work. Save up for decent gear, my sony walkman still working to this day and ifi idac2 still works well after years of use. Cant say that to any of my topping, smsl, fiio, etc china crap.
Is there any dac that you could recommend that could possibly overcome/ make up for la90's weakest points? According to your reviews I was thinking about Gustard X26 Pro...
Not enough minerals! Oh wait, it's the wrong chat. Not enough power with Suzy, lightweight, too polite and up-front sounding with them, I wouldn't get it for Suzy
@@Soundnews nothing to do with power... it just lacks coloration. Open back headphones lack weight behind bass and vocals and need coloration. Not enough power is just bullshit.
@@Nuevo_El_Nagual I bought if for my HE6se and returned it shortly thereafter. It's got a nice black background but the bass had no slam and the treble was too smooth. Switching to high gain actually made the treble a little hot.
Thank you for this review. I am trying to find the optimal solution for my upgraded setups #1 and #2. From an economical and value-for-money standpoint, I was looking either towards room correcting Genelec Ones, wireless KEFs -beautiful looking speakers and the most economical option, or possibly some passive speakers with something like Lingdorf amp with room correction, which probably would be the least economical setup. What are your thoughts?
My experience would be not spending $900 for some stupid 65 watt per channel amp. Fools with to much money go for it. I guess the Chinese think Americans just have tons of money to through away. I'll stick with what I have. Companies have lost their reality for pricing in today's market.
Great review!
Can also you review the new Topping B200 mono and compare it to LA90?

Internal units traps more heat inside which I think is good to avoid
Thanks!,

I feels that way, at least for now

Agree on all fronts
I am interested in what a Pa5 is. Never heard of them before. Can you tell me more? Thanks.

hard to tell, as I've used it only for a few weeks and this is a new model

hi. you will test Topping A90 Discrete?
It will happen at some point, probably next month
@@Soundnews I'm looking forward. you are doing a great job
Hmm, should I replace my PA5 with this one? I'm driving LS50 meta's.
I don’t think there will be much of a difference between those. If you want more headroom and power I‘d go with the Purifi class D amp
I wouldn't do that. PA5 is (still) more powerful, but not as technical as LA90 is.
Get 2 LA90S ;]
I have this and PA5, you won't hear a difference. Both are flat and have a no noise.
how’s it sound with Susvara?
Same query here

That power supply is a no-go, what a shame!
I have a separate power supply on my Naim amp and Cyrus amp. Definitely an improvement.
Did you tested it as monoblock?

What KEF towers are they in the background?
I mentioned them at least 10 times in the video, those are KEF Reference 3
