Aiyima T9

Can you use a slightly beefier PSU (36V @ 6A) to give it more welly like you can with the A07? Or will that make bad things happen?

Really loving the T9 Pro so far, but it can't quite touch the power of the A07.

Trying to decide whether I like T8 + A07 or T9 Pro the most.

Higher sensitivity speakers are another obvious option. What are you currently using? I would not go above 32v as is the supply Aiyima sells for the T9 Pro, it could raise risk of a circuit component failure.

Chip's max input is 36V, best case scenario you gain +35W (at 10%THD lol).
And since at the butt of the unit says upto 32V input, I think it would do more harm than good to opt for 36V

Imo, just wait til they launch "T9 Pro+ Special Edition XXX" and hope they just use better chip.

What better chip?

Any ideas why it says max 32V when the chip can handle 36V?

Wharfedale Evo 4.1. TBH it's plenty loud, but with my A07 it sounds nicer and goes louder with a 36V which is why I ask.

Board not designed for max voltage prob for cost/benefit reasons.. diminished return

yeah, makes sense!

Alternatively was thinking going from T8 into 2x Audiolab 8000Ms but not sure how to wire monoblock inputs tbh

A07 is a diff chip tpa3255 right? This chip is max 48v I think.

Enjoying the T9 using its internal DAC to stream music from a small tv/monitor. The perfect all-in-one amp for this purpose. Picked this one up cheap on Amazon as they were being closed out to make room for the more expensive T9 Pro which I understand sounds the same. With hours of play time I've not heard one click that folks seem preoccupied with.

Tubes can add warmth to class D amps which can often sound a bit dry.

 

[gnat_leader]

I doubt the T9 Pro sounds the same esp with good revealing speakers. All the chips and the tubes are different. How on earth could it sound the same witha a completely different circuit design?

No idea. Wild guesses; board design decisions, safety headroom, lower power lower heat/components standard etc etc.

the T9 Pro the mode selector cycles through usb/coax/bt/aux/opt. But how do I set it to RCA to use as a simple amp?

One of the modes will be it, possibly aux

But it's not working - in any of the modes.

If I set it to bluetooth and connect to my phone it works great, so I know it's connected to speakers right.

And when I switch it out to another amp - that one works too.

LOL never mind it works in aux. I had the amp's volume on like 30 and it was too low, needs to be on max. Thanks

 

[Megaken]

Is it ok to just keep it on forever? Or is it better to turn it off when not in use

The RCA is input and so the volume will be also subject to source output which may have been low. I’ve heard the aux is a variable output so what will that mean for an active sub? Will the T9 Pro control speakers and speakers output equally?

Mm I just set it's volume to max and it works like a regular amp without volume control. I control volume on the preamp.

My dac has a volume control too, so I have 3 volume controls, but that's another topic.

Ok, I have an T9 Pro on the way and would like to use a sub with it and never owning a sub before I was wondering if I would have to adjust the volume of the sub as well as the T9 to match them up or would the T9 do it all….?…I understand the initial set up would take some tuning but after that would the T9 be the master variable?
