Hello all. I was thinking about Making some upgrades to one of my two mono block (Emotiva UPA-1) just to see if it is posible to get something more out of it. And then put it up to a scoop and see if i can see and hear a diffrence 🙂 I am doing this as fun thing to do for a weekend project. What do you all think will it make a diffrence ? 🙂
First thing is changing The speaker connections...... they must be one of the cheapest there is. RCA connection maby ?. And then there is the caps, i have no Idea if the are any good at all, they are Seacon 10000uF 50v. I cant find any info at all on them so dont know if they are good or bad. If i was going to upgrade it, what whold be some good caps to change to, it dont have to be any high end caps just some that are known to be a good price/performance. If it Will cost 200€ to upgrade each then it might not be worth it ? All the small caps whold be cheap to change out so that i can do just to see if it makes a difference.
Tell me what you se that you whold change 🙂

It worked now 🙂 i also found something strange om 3 places it says 4u7 but two of them are Rubycon 47uF and one is 4.7. Did someone make a misstake ? 😛
What about the utput resistors of 5w 0.25 Ohm. Some say that that type make alot of noice, is it worth changing ? If so, what whold be the best thing ? Like i Said before this is just an experiment 🙂 also the internat wires, maby getting shelded cabeles ?

Also the chassi isent grounded, it is metal so why is it not ? Sounds a bit dangerous. Is there any chance of degraded sound quality ? If not i cant understand why it isent

Any possible silly thing, SOME one will say it.
Many hi-fi systems run un-grounded perfectly well.
The speaker connectors look fine to me?
If you are displeased with the amp, sell it on.

Yes i have seen after a bit of looking around that alot of amps arent grounded and that people how had grounded some have Burt up 🙂 just think it looked a bit strange at first,
That speaker connection feels super cheap and when you twist it it always makes a iretating noice, there are amps for under 70$ that have better connectors Then this. The big Brother XPA-1 got the ”normal” connectors.
I am not displeased with the mono blocks i like them (exept the connectors) i just want to see if they can be better with higher end components inside that is all. If it dosent make a change i will just have one amp where the parts will probobly live a litle but longer then the othere. If it sounds bad after the cap change i will just put them back, and i Will be out 50$ but i will know a litle but more
