Default Aleph30 bridged... does it bring any advantage?

Hello,
recently I sold (due to the way too low WAF) my DIY Aleph30.
The buyer is very satisfied (as the price was a sort of giveaway) and now asked me to make another one.

When I asked him the purpose of this secon amplifier he told me that he wanted to bridge them.
I told him that, being the Alephs class A amps (and therefore current limited) he would gain almost nothing but he insisted that a friend of him actually uses 2 bridged stock Aleph3 and likes them more than a single one.

In the end, what is your opinion about that?

Mine is that a Aleph5 or a Aleph2 or a Aleph-X can be a better solution.

Cheers

Andrea

As the output current is limited, bridging doesn't bring a lot
to the table unless the load is significantly above 8 ohms.

If the load is 8 ohms or less, then paralleling channels has
a lot of advantages, and is recommended.

Hello Nelson,
Thanks for the confirmation (about the bridging) and for the suggestion (about the paralleling)... I think that now I'm doomed to build the second amp...

Another question: since I used regular 5% resistors, the possible mismatch between voltage gains can give me troubles?

Cheers

Andrea

Mr Pass

i dont understand how parallelling amplifiers can be an advantage.

Dont you get the same with one heavier amplifier as the A5?


Regards
Edwin
