Does anyone have experience with the Kef LS50? - Page 14

post #196 of 203

Do I need a new power amp for these, or is my AVR sufficient?

 

Longtime headphone user who is doing my first speaker setup.

 

Just ordered the LS50s.  Wondering whether my AV Receiver has enough juice to run these properly as 2.0 or if I need to get a new power amp to put in the chain.  They will be used in a room that's 11x14' at moderate volume. 

 

Can you guys give me some input?  

 

Here are the AVR details:

 

Yamaha RXV775WA

Published materials provide the following, but as you know, not all watts are equal, which is my issue here.

90W per channel (8 ohms, 20Hz-20KHZ, .09 THD, 2 channels) 

Dynamic = 250w (2 ohms), 210 (4 ohms) 180 (six ohms) 140 (eight ohms)

 

Thanks,

 

Ryan

The AVR should have sufficient power though Yamaha's specs are usually very optimistically rated. Whether it going to sound anything decent is another? I have found Yamaha AVRs to be a bit thin sounding when it comes down to stereo which definitely comes down to the internal amplifiers, but as a processor and pre-amp they usually do a good job. An external power amp might give you a bit of a warmer and full bodied sound. If it was my money I would try out the NAD T748 first. I bought my LS50s based on a demo running on NAD amplification and it is a great combination.

Thanks for the info guys. 

 

In terms of optimizing the sound in the NAD power amp context, would this work well?

 

 

Source material ---> Yamaha AVR, using pure direct feature + pre-out ---->  older NAD 2200 Power Amp  -----> LS50s

 

Also, what would you say is a reasonable price for a used NAD 2200 that is a little older?

 

Really appreciate your feedback.

 

Thanks.

This really seems like a redundant setup. The LS50s are small speakers with realistic dynamic limitations, you're not going to get more out of them with a NAD than the Yamy. At louder volumes they'll begin to distort regardless of amp, as will all 5" woofers playing fullrange signals. Your AVR will take the LS50 up to KEF's stated 105db limit without a problem. As for Yamaha AVRs being cold - I would take that as one person's opinion of one experience with one model, not necessarily fact.

I heard this amp with the Dali Ikon 5 Mk2 and it is a brilliant little valve amp. Sure it must sound great with the LS50!

it complements the ls50s well, gives them more "body" than the roksan kandy k2
