Hi there.

I am hearing great things about the new kef ls 50's.

What is the best integrated amp for the ls50's?

I like female vocals, jazz and alternative.

What is your recommendation under 1000 and over 2000?

So far I am interested in the Nad c390dd. But not sure its worth the price.

NAD C 375BEE is highly regarded for about $1500. The 390DD is also a fine (better?) piece but about $2500. Their new digital drive stuff looks very intriguing. I don't think you will go wrong with NAD. LS50s are some awesome speakers, what sub do you plan with them? i am asking because you may want bass management so check that part out.

Main Kef: Reference 205/2 & 202/2c, Surrounds: Kef XQ40, Velodyne Optimum 12, Integra DHC 80.3, Oppo BDP-103, Bryston 4Bsst2, Parasound Halo A31. Second B&W: 685 (3), CCM618, Def Tech Powerfield 1500, Onkyo TX-NR1008, DBP 2010, Samsung BD-C7900, Zone 2 Klipsch AW650. Sitting still CCM616, Kef...

I was not planning on using a sub. I will use them for 2 channel audio only. I was hoping I could get away without a sub. Am I mistaken?

Those speakers are small, you will want a subwoofer.

According to the specs those speakers only go down to 79hz so you'll probably want to add a subwoofer to your setup.

Design: Two-way bass reflex
• Drive units:
• HF: 25mm (1in.) vented aluminium dome
• MF: 130mm (5.25in.) magnesium/ aluminium alloy
• Crossover frequencies: 2.2kHz
Frequency response (±3dB): 79Hz - 28 kHz
• Frequency range (-6dB): 47Hz - 45kHz
• Maximum output (SPL): 106dB
• Sensitivity (2.83V/1m): 85dB
• Amp Requirements: 25-100w
• Nominal impedance: 8Ω (min. 3.2Ω)
• Dimensions (H x W x D): 11.9 x 7.9 x 10.9 in.
• Weight: 7.2kg (15.8lbs)

I just brought a pair of KEF LS50's home. Love'em on my main system. I will be powering them with a Prima Luna integrated amp, it's my opinion that the tubes will mellow the all metallic driver. This will be a secondary system and I am not planning to use a sub.

Hi mate.

Let me second your thought for the C390DD. I havent heard it, but from what I've read I wouldn't have any reservations sound quality wise.

The reason I'd opt for the NAD (or Peachtree Grand Integrated, the only other amp/dac to take this approach, albeit for more money) is that it has a high-pass function (40-200hz). Unless you only listen to girls with guitars in your bedroom, the very best thing you could do for the Kefs would be to relieve them of low and even mid bass. The Kef appears to be a world class speaker in everything but bass - expecting a 5" driver to do it all is silly. Build yourself a pair of Rhythmik servo subs on the cheap and cross them over to the LS50 at 150hz and you've probably got something approaching the quality of the Blades for a fraction of a price.

I will most likely be getting ls50's and rhythmik for mainly for rock listening in an 11x12 room. I want to spin vinyl via a vpi scout as well as cdp. Would that change your amp recommend? Any help/ suggestion appreciated.
