NAD 375 or NAIM 5i or NAIM Unite Qute


I inherited the following system:

Arcam alpha 7se CD player

harmon kardon AVR 120

b&w 303 bookshelves

monster power conditioner

It was an HUGE upgrade to what I was using before. Its been a joy listening to music again and exploring the new details and such. It's been 7 months and I've been thinking about where else I can take the sound. It's been fun to learn more about the hobby.

After researching and visiting local audio shops it's become clear that the HK is the weak link. I really only want a 2 channel system. No radio. I'm looking for advice and thoughts on amps. I'm thinking an integrated amp. Although I've never heard tube. These are the two amps I'm looking at now:

NAD 375 (new, $1200 + 13% tax)

Naim Nait 5i (used $850)

Considering Unite Qute

I want to get more out of my b&w's but I'm sure I'll want to upgrade speakers in the next year or two. So I want to be prepared for that with my next amp purchase.

A couple of other things that I've been thinking about is the whole tube option and whether I even want to go down that route. From what I've read it's a warmer sound , which sounds interesting to me. But more money and maybe more maintenance.

Secondly, high res music. I don't currently own any but wow I heard it at one of the shops and I know I'll want to get into that. Should I be considering that in my amp purchase?

-----

My music tastes - from Zeppelin to Elvis, vocals, acoustic, soul, blues, classical , hip hop.

Interested in live sound, 3d imaging sound stage, non fatiguing , joy of listening, soul moving.



Thanks in advance!!

I've listened to both. I found the Brio-r a bit more refined. Little more detailed. I found a bit more harshness with some of the treble on the NAD. The NAD had a lot of "attack", coming at you. The Brio-r had it too but not to the same degree IMO. Overall I like the Brio-r sound better. Still haven't made a decision.

In regards to the DAC, you mentioned that you are using the DAC in the home theatre system. How are you sending the digital file? I'm just trying to understand this as a novice. I wasn't aware that there are DAC's in a home theatre receiver.

Yes, all HT receivers have built in DAC's. Most now have HDMI, optical and USB inputs. I am not currently streaming any digital files from a computer to listen to - my sources are LP's, CD's, SACD's, and of courese Blu-rays & DVD's.

LP stay in the analog domain, from turntable to 2 channel pre-amp. CD's can go this route too or through the HT receiver (altho I prefer the analog route into the pre-amp). SACD & Blu-rays are bitstreamed into the HT receiver via HDMI and this is where the HT receivers DAC's are used. If I wanted to stream from a computer or apple TV, I could do that to into the HT receiver and utilize its DAC's.

As a beginner, it looks like you are off to a pretty good start. The differences you notice between the 2 amps is very relevant. That's exactly the type of thing you need to be listening for. More importantly, you know which one you prefer. (And its always the more expensive one, isn't it?) There's just nothing like hearing it for yourself. You can read all the equipment reviews you like, but the way you're doing it far better and much more rewarding. Who better to build your system than you.

What were the other components in the systems you listened to? Since you can only listen to a component as part of a system, getting to know all the parts of that system will be extremely beneficial in your search for better sound.

Zd542 - Thanks for the advice and affirmation that I'm on the right track with this. It's very fun, and addictive.

I'm actually coming to the conclusion that I am preferring the NAD lineup for now. I really liked the dynamic range. But more importantly, I think, that the combination of the Dynaudio Focus 160's will lessen the harshness in the highs I mentioned before. I believe it was the B&W's that were taking it overboard. A huge part of the NAD option is the price. I can always upgrade later to a more "musical" option such as Rega or Naim (do any of these amps equal the dynamic range that the NAD possesses?).

When I listened to the Brio-r it was with a Naim CD player. I've also listened to Harbeth speakers with audiolab amp, audio lap dac, airport express. I listened to the Dyn Focus 160's with a moon 220 amp. You're right, all the other parts have an impact, so trying to make sense of it all can be tricky, but I think I'm getting decent at it.

I feel comfortable with choosing the speaker first. It seems to have the biggest impact on the sound characteristic of the whole system. So I'll start there, then start to add the other components such as amp and Dac.
