My Very Low Budget Nearfield Desktop Rig (Lepai amp and Dayton Audio speakers)
Aug 5, 2014 at 8:19 PM Post #152 of 193
Hi Guys, just a quick question. I'm plan on setting up a pair of good passive speakers paired with Lepai AMP and my budget is around $150. Would this be a better (SQ) route or should i go straight to active monitoring speakers for $150? Hoping for your inputs. Thanks.

I think so.

The Pioneer SP-BS22 are very good sounding speakers for the money. They would fit your budget. And sometimes they go on sale.

Hey guys.
Can I use a power supply with 12v and more ampere for the lepa amp?

A laptop power supply could do the job?

I can't reach what difference could exist if I use 12v or 13.5v as it's suggested on the box of lepa amp...

Thanks

^^^ It will work as long the plug fit and have correct polarity with the middle pin/tip is + or indictated.
More ampere is no problem as the Amp can perform better with more power.
12V is good as the Amp has built-in voltage converters/stabilizers to accept variable voltages from 12V-13.5V.
12V can be better as generated heat will be abit lower than using 13.5V.

oh OK. But how many ampere could I give to amp?I don't know what power supply I'll find at market. So I don't know what's the maximum I have to ask. :wink:

What is indicated on the amp? its usually minimum 2A.
Your amp will limit how much minimum Ampere it can use by itself not by how much more it can get.
The factor is the Powersupply's price is higher the more Amperes the Powersupply can deliver.

Yes, a standard 12V/2A powersupply will work.

Yes, its good the same standard bigger sized output plug, it will work.
Probably buy one in Italy then, faster and no missing post but expensiver, your choice.
I think I need of a stabilised power supply. To have always the same voltage of 12a... What do you think?
