Review: Levinson No-331 Amplifier

Category: Amplifiers

I mostly listen to small ensemble jazz, jazz vocals, pop and classic rock.

I test equipment mostly using analog sources. ie:vinyl. Classical music and female vocals are to me the best music for equipment analysis.

What I look for in evaluating equipment is inner detail, proper image placement and most of all musicality and "sweetness" to my ears. When everything is right, my ears are buzzing with gratification. I hate overly bright sound. also veiled sound that sounds muffled and unclear.

The levinson 331 has been in my system for only a few months and I am still evaluating it with my Apogee Caliper Signatures which I love. I had a Audio Research D400 200 watt per channel amp prior to my purchase of the Levinson, a 100 watt per channel amp.

The 331 has a much different sound as compared to the AR.

I would describe it as less up front, a little bit darker, with better image front to back imaging. Also, when I first hooked it up, it had a sweetness to the highs that I would describe as "silvery" which is characteristic of most Levinson amps that I've listened to in the past. I really like this effect but I am not sure if it is accurate. Also the upper to mid bass is a lot more detailed and controlled compared to my old amp. This I like a lot! The Levinson amp mates very well with my tube preamp, an Audio Research LS16. Tube preamps mate with SS amps very well.

If I had the cash, I would go with a higher powered Levinson amp. The Apogees will distort when the music is pumped up to really high levels. I think they are crying out for more power.

There's a lot that I liked about the S300. It seemed to have loads of power and control and never made my Apogee's object. However, it just sounded too dry and bright most of the time. I was always trying to tame the highs with cables etc until I gave up and got the D400. I never did get to try it with a tube preamp (I did not have one at the time).

I've never owned a 27.5, but have heard it on my system. It has the Levinson characteristic in the treble which I like so much, however, as I remember less control in the bass. It seems to me the 331 has everything the 27.5 has but with more bass control.

Yes, I noticed that Audio Review had a few negative comments on the 331 which I really don't understand. This amp could be more speaker and system sensitive than the older Levinson series. However, every professional magazine review on the 331 that I've seen has been positive including Larry Greenhill's in Stereophile which gave it a class A rating at the time.
