Can you Gurus please suggest me which of these makes better sense to buy.

I am ordering this in 2 days from now. Quick response will be greatly appreciated

Thanks in advance

I say Infinity and Kenwood would be a better pick.
Also, look at SoundStream Reference series amp.

[Slasher]

Go for Infinity Kappa 4 without a second doubt. 106dB Ref. SNR Class D Monster. If you want pure quality and power, go for Infinity. Kenwood Class D 4 channel is available for as low as some 8000 and Infinity Kappa 4 around 39000, and just think that everything comes for a price, and so is the quality... I hope you will make a wise decision..

Infinity Kaapa Four is the way to go man. Its the best between these 3

[procircuit_234]

which is better choice to power front compos and rear coax(SPL setup)
infinity kappa 4
DLS RA 40
moscono gladen one 120.4

DLS RA 40 !!!!

Mosconi is nice too , but RA 40 has won many awards world wide for its SQ so DLS is my pick

HI there

These are exactly the three amps that I have finalized out of which I need to choose one.
I am more inclined towards Kicker due to more power.
What do u say guys?

Mi10, What have you finalized?

Thanks
