L15D + A1000SMPS, Enything better at the price?

[tobiazz]

Hey guys.

I wanna build my own amp, but as im bad at sodering, i wanner buy moduels.

I found these:

Assemlbed Stero L15D Audio amplifier board IRS2092 IRFI4019H | eBay

Along wiht

Connexelectronic

Now the questien is, should i finde something else? Im looking for SQ here?

If lets say my budget is 300-500 dollars tops??

And sorry for my english.

I think you would be better off with buying an amp from connexelectronic, I think they do PS and amp combinations, two of those ljm amps fully built for just £15 each you really have to think where they saved the money.

Christi, the designer of connexelectronic kit, is a member on these forums and seems very keen on producing good quality electronics.

FYI ljm is also a member of this forum and has very good reviews from forum members. Just like to set the record straight. The L15D and L20D are on my shopping list.

Isn't that psu overkill?
Is the speaker protection also required?

Well ....... perhaps! The 500W supply would be sufficient into an 8 Ohm load. Truth is the price difference is so marginal that the 1000W looks like a bargain.
The idle power for both is insignificant.

I see your point.
Is speaker protection always recomended, or is it only necessary with linear psu?

IRS2092 amplifier modules are available from 150W to 600W on 4R load here Connexelectronic they have on-board speaker protection circuit, and the power supply which can be used with them can be as follows: SMPS300R for two 150W modules or a single 250W module, SMPS500R for two 250W modules or a single 400W module, SMPS800R for two 400W modules or a single 600W module, A1000SMPS for two 600W modules. Connexelectronic
During testing, i measured around 750W on 4R at 0.6% THD on a 600W module supplied with +-92V. so the 600W delclared power is real, with max. 0.1% THD with module supplied at +-82V.

Okay, yah the 1000w smps is a bargin i would say, but, im looking for the best sounding amp for the price, wiht a minimum of 100w continuesly in to 8ohms, so i dont know if the ta3020 souns better than the IRS2092, i have not realy found a god deskription of the sound ?

Thx for the awnsers

Cheers Toby

Connex, LJM, Hifimediy, all participants in this forum with great modules available. I have a pair of L20D boards I'm itching to check out, haven't heard them yet.

By no means was I doughting ljm's designs merely the quality of the kit being sold here.
