I prefer the sound of TB10D compared to ZA3 monoblocks. I use the TB10D to drive a pair of 6ft tall Genesis APM-1 speakers and it sounds like a dream. I have owned expensive, heavy amps like Krells, Threshold, Parasound, Lumley and Grant valve amps and the sound of this mini TB10D just blew me away. I don't use any preamp at all...I plug it directly to my CD player and it sounds very detailed and transparent. The only reason I bought the ZA3 is because of their XLR input but quite disappointed because the TB10D sounds better.
Olá amigo! Esse Fosi tem baixa latência no bluetooth? Quero usar para tocar um piano virtual a partir do iPad. Você acredita que a conexão iPad - Fosi funcionaria com pouco delay? Muito obrigado
By measurement, the 32 volt adaptor gives you ... 50w/ch on 8 ohms 90w/ch on 4 ohms Note that the supplied 5a brick will shut down at high volumes on 4 ohm loads. If you want an experience ... hook it up to a pair of Klipsh Heresys.
@@gasolin75 Yes you will get more power at 48 volts ... about 100w on 8 ohms and 200w on 4 ... BUT, the amplifier's gain does not change with voltage. IF you have the volume set to 50db in your room and you swap in the 48 volt supply... guess what... still 50db. What you gain with the 48 volt supply is more headroom before clipping sets in. Don't expect some magical transformation.
Heck ya on the hereseys. This amplifier will blow your windows out using vintage high efficiency 100db+ speakers. A few watts on high efficiency is nuts, and the amplifier barely works and is always in the lowest distortion capability of the amp.
Apparently Fosi Audio are soon to release a new version of the FOSI AUDIO TB10d that will be compatible with a 48v power supply - unlike the one I recently bought and returned the BT30D Pro that wasnt and didnt take full advantage of the 3255 TI chip
@@MakeLifeClick I think you may be correct and I probably didnt state my post correctly, while it was compatible, it wasnt ( 48v power supply) wasnt included and had to be purchased separately. to take advantage of the chip and get the stated watts per channel, plus there were other problems hence edition 2, then there was the BT20 Pro and BT30 Pro which isnt compatible yet claims the same power output, going back and forth with the 48v compatibility. Now they are soon to release yet another new edition of the TB10D which i was told is compatible...Now you can be as confused as I am.
@@vinylmonster4907 The TPA3255 chip has always been 48 volt capable ... the safe max is actually 51 volts. The limiting factors in the various designs have been 36 volt capacitors and poor thermal solutions. The TB10D has always been able to do 48 volts. The caps are 50 volters and the heat sink is adequate for short periods of very high power. It is unlikely you would overheat it with decent music, but on some highly compressed stuff from the loudness wars you might get an occasional shutdown.
I just purchased one of these and received it today. The tone controls have no detent for flat. Is flat EQ in the middle of the pot's travel? Are these cut and boost? This is not addressed in the included manual and the Fosi website can't be reached.
I've had the Improved version of the Fosi TB10D for a couple of months now and I am also impressed. I use it to power a pair of the Andrew Jones designed Pioneer tower speakers and content coming from my TV through an optical to RCA converter. I've also had output from my PC through a Dragonfly Black ver 1.5. Both sound great but I tend towards the optical out source. Having the Treble and Bass Controls is an added plus. I've also used an iPhone 11 with adapter to RCA as a source for streaming with Amazon, Spotify, Pandora and Internet radio stations like KUSC out of LA at 128kb and been happy with the results. I do find that using an equalizer and bumping up the mids gave a much warmer and pleasant sound. It took awhile to adjust the tone controls to sound the best with multiple sources and types of sound/music. I've coupled it to a Topping Dx3 Pro + and it's a good match. I tried it with the S.M.S.L. C200, which I think was defective as it gave a gritty sound I couldn't listen to for more than a few minutes. That went back to Amazon the day after it arrived. I've tried it using different RCA cables I have, some going back to the '90s and made by Monster (one copper color model was unlistenable the other, blue and directional, better). The best results came from a modest set of RCA cables I bought from Amazon that made the list of 'Best RCA Cables' when I did a search but I think any pair around $10 will be more than good enough.
I agree that you need to spend some time with the tuning of this to really find the sweet spot. It’s now powering floor-standing energy speakers and sounds great.
Oh my god! It sounds awful! You saved me $100. BTW, you're not getting 300 watts out of that with the included adapter (or any other adapter). 50 at best at 4ohms. Half that at 8.

Mine has never shut down at loud volumes
@@harrykain285
When I say high volume I mean right at the edge of clipping.

Interesting - I thought the TB10d with the 3255 chip could take a 48v supply? Maybe I missed something.

Hi. Im from india can we connect this with polk audio t50 tower speakers or yamaha NSF71 towers. Please suggest me
Of course you can
Can this unit power a stand alone in ceiling stereo speaker like the Polk audio v6s?
oh yeah, no problem. Doubt there's much it can't power.
I just purchased one of these and received it today.
The tone controls have no detent for flat. Is flat EQ in the middle of the pot's travel? Are these cut and boost?
This is not addressed in the included manual and the Fosi website can't be reached.
I’m pretty confident mine has a ‘click’ feel for flat. I might be confused with my Fosi headphone amp. I’ll check.
@@MakeLifeClick Thanks. There's no hint of a detent on the tone pots on this amp.
I'll just have to assume that "flat" is straight up.
The "flat" position is with the white lines straight up.
Boost and cut 10db on bass below 350hz, 8db on treble above 1500hz
can you limit the power
You could use a lower power supply. Fosi can advise specifically what.
Sure ... just turn down the volume.
Do you think this amp with the Q Acoustics 3010i would be a great match for a desktop?
Thanks a lot
Yes, I liked them on my q acoustics. Are you putting the q acoustics on your desktop also? Bit too close maybe?
@@MakeLifeClick thinking of it. I have an old JPW mini monitor but want to upgrade
Thank you for the video. If I want to run the Fosi as a power amp for a vintage reciever (with pre outs) then how shoud I connect it?
@@Douglas_Blake Thank you
Just to add here - the Fosi BT20a Pro has a pre out. It’s a newer model but I do like the sound on this model.
Sorry! Just read this again - you want it as a power amp. Ignore that comment format but it would still work as it has RCA in up to 300w @ 4ohms.
