The real revolution is the Texas Instruments IC chips that these low cost high performance amplifiers are built around. Kudos to Fosi & Ayima in applying those chips, pioneering low cost & high performance amplifier products. Established companies (like Yamaha, etc.) need to do the same with their receivers, lowering cost & raising performance at the same time. Credit companies like Texas Instruments (❤ to Texas), who is continuing to design better class D amplifiers while keeping the cost low, charging just $6 per chip from Mauser electronics. We live in a new golden age of amplifiers.

I’ve been playing with the V3 for a while using the 48V 5A power supply and let me tell you, this thing really benefits from active cooling. When it gets warm the sound quality falls apart quite a bit. What I discovered is that a computer fan set at a low speed brings the case down to near ambient temps so it doesn’t take much but it’s really worth doing.
@gamerman644 9 ай бұрын
if your v3 is getting very hot i would recommend trying new thermal paste and adding some to the metal that touches the case in between the heatsink and case has none. i did this to mine when i swapped opamps to OPA1656. but my main point is im running the v3 with 48v 7.3a and was using it with a 48v 10a and never had a problem with heat at all, my dac gets more warm in the stack than the v3

Yay, I'm sooo glad you and Fosi got in touch for this as I tried to tell ya about it in email, lol. They had like 20 of their customers provide input on something next level. The swappable op amps are even better with Sparkos. The heatsink is now away from capacitors underneath the board and better airflow means less deterioration of the caps long term. Have you seen the guts inside? Top shelf... so happy my favorite reviewer got his hands on a product I feel a part of and thanks to Fosi for their listening and production of something so valuable for the price point. They even are now an authorized resales for Sparkos op amps since so many swap for them, so the future looks pretty interesting

I would not stretch too much and say the V3 components are Top Shelf, there is still room for improvement. Its Elna capacitors are the bottom of Elna audio grade capacitors. The Elna Silmic II, Those are top shelf, or Nichicon Muse UKZ or Fine Gold UFG. But I get your point, the V3 uses better components than the competition and other Fosi amplifiers. If you are handy at Soldering, you could replace those components yourself.

I'd like to test if the variable power supply is changing anything itself. In other words test it with the bricks Fosi sells. And for speakers use Klipsch (high sensitivity) vs Micca RB42. I can tell you because I tried the speakers, the Miccas walk all over the Klipsch but you have to crank the volume knob to do it. With Miccas you really need the 48v brick, with Klipsch you don't. They both sound good depending on if you like the speakers sound signature. edit: wrote this before I saw the entire video

I have both but prefer the V3. Z repeatedly said the V3 and BT20A Pro have the same internals, they do not. Looks up photos, the V3 has two massive caps the size of your thumbs, the BT20A Pro does not. Also see ASR measurements, both are better than the TB10D but the V3 is king and you can hear it. I’m a little surprised Z didn’t hear it. When listening to both the V3 has better, flatter bass extension with a slightly cleaner, more delicate sound. The tone controls are pretty nice on the BT20A Pro but I’d still recommend the V3 over it if you can work on your room to minimize you need for EQ. The BT has a really inconvenient Bluetooth implementation, it is very annoying to switch between inputs because as soon as the device is on it connects. Reset to unpair. Works fine in either mode, just not both regularly.

Yes. The V3 is the first to offer a decent quality components: coupling capacitors and output filters inductors and capacitors. All these amplifiers have a very similar design. The difference lies on the components. Having said so, you can always upgrade your amplifier components to whatever you prefer. The problem with the BT20a pro is Fosi failed on the coupling capacitors and on the output filter capacitors. But they did correct them on the V3. Unfortunately, there is no room for inductors upgrade like Wurth or Coilcraft (expensive ones) like the ones Topping used on the PA5. Those inductors make all the difference in the world. The A07 does have room for that upgrade.

The posi v3 and posi bt20a have different heat sink designs. Thus the v3 can pull a higher amp draw without heating up as much . I think, the v3 can sustain a higher output for a longer time. The v3 uses the aluminum body to dissipate heat. And the bt20a uses a conventional finned internal heat sink. I think v3 has a much better heat dissipation .

@josephshim2744 Жыл бұрын
@@SpirallingOut powered the 1.6s beautifully. But sold 1.6s for a pair of 3.5s. the V3 powers them great at normal listening levels, tried to see what their limit was and tripped the built in protection in them. Waited 5 minutes and it was running just fine again. But at the time I didn't test with a sub & xOver so it might just be drawing too much to fully handle the bass at that volume level. I was also driving at uncomfortably loud listening volumes. Bought another one to try to bi-amp and see if that will handle things. Because if this tiny little amp can power giant Magnepans properly then I can't think of a reason to keep my crown power amps which are massive in comparison; not to mention more expensive. So long story short they should absolutely be able to handle the LRS+, .7, or the 1.7i. just need to see if they have enough headroom to push the 3 series if bi-amped.

@@josephshim2744 That's amazing! I bought one to pair with the Modhouse Tungsten after they finally release, but now I'm thinking I just might also put aside some pennies for a couple more V3s with the 48V/5A power supply and power a couple of LRS+ and 2 servo subs. The LRS+ have been my endgame speaker ever since they released and I started seeing people compare how good they were to other, insanely expensive speakers. Problem was they often were paired with really expensive amplification to wake them up. I'm absolutely chuffed I can power them for a couple of hundred dollars now that LRS+ has gone up in price over here. I'll have to try rolling V3 op-amps for the Maggies too. I hear Burson, Orange, Sparkos and a few others do some really good sounding ones, with a little case modification with a Dremel for clearance. I plan to try them all for the Tungsten too. Thanks for the info.
