Review: Ayre Acoustics AX7e Amplifier

Category: Amplifiers

I usually give my ears about 100 hours to break in when getting a new amp before coming to conclusions about it. So although I have only had the Ayre AX7e a short time (about 20 hours of listening), I feel very comfortable declaring that it is delivering what I have been seeking in an integrated amp for the last few years. Having gone through Rotel, Arcam, Parasound, and Simaudio amps, I nearly concluded that it was about trade offs. One amp had clarity but was not musical, another musical but had no dynamic impact, another had good bass but brittle high frequencies. The Ayre somehow weaves all the qualities I look for without really compromising on anything.

As Art Dudley noted in his Stereophile article, the amp powered is silent. Even with my ears directly against the speakers, I could barely detect any energy or hum. This is important to me and I think contributes to the component's ability to reproduce dynamics. As another audiogonor put it "if there is hum, I don't buy it!"

Dynamics - this amp brings out dynamics like nothing I have heard before. It seems to respond without hesitation to quick changes in dynamics and reproduces them well at any volume. Listening to Rachel Podger's rendition of Bach's Violin Sonata's and partitas, the shifts in dynamics even as the bow is drawn across a note or in a rapid 3 part passage can be clearly heard.

Soundstage/clarity - Separation of instruments and vocals is excellent with a broad soundstage that has depth but is never too far forward. Listening to Crosby Stills Nash and Young sing Helplessly Hoping, each voice can be heard distinctly in it's place in soundstage.

Naturalness of instrumental timbres - I have heard amps that deliver exceptional separation of instruments in the soundstage but the instruments don't sound natural. Pianos in particular sound more natural and present in the room than I have heard. Pianos are particularly difficult to get right because of the range of frequencies, variety of attacks and the complexity of overtones in the notes. I nearly jumped off the couch when I first listened to my favorite Horowitz CD, The Last Concert. The piano was right in the room with me, the sound eminating from the right height and position, each attack clear, the timbre natural. Instruments sound just like they do when listening to them live. I found vocals to be exceptional on this amp both in timbre and relative placement and size in the soundstage.

Bass - One reviewer compared this amp to a Krell and suggested that it didn't have as much bass "slam". I am not sure what "slam" is. True, I don't listen to too much rock anymore but I do listen to some pretty driving dance and musicians like Afro Celt Soundsystem. I have also been a bass player all my life. My take on the bass is that is has the right amount of attack with the addition of an exceptional amount of timbre. I can tell whether the bass is a Gibson, Fender or Alembic; whether the acoustic bass has metal or gut strings. In fact, acoustic bass reproduction is exceptional on this amp. Additionally, when I first looked at buying this amp, I was concerned that it did not have pre-amp outputs for a sub-woofer. However, after tweaking my sub to use speaker outputs, I have found that integrating my sub was nearly seamless and the overall bass sound is greatly improved using the speaker outs.

Controls and connections - First I have to say, I love the CARDAS Speaker binding posts. Even connecting 2 sets of spades to each, I found that once I had everything lined up, it was simple and certain getting a tight connections without any tools. I also really appreciate that the volume control has 1 db increments. Previous amps that have had large jumps in volume steps have annoyed me to no end. The display and buttons are nothing remarkable but do work.

Musicality - This amp makes music, plain and simple. I can't compare it to tubes nor would I say it is tubelike. I don't really care if an amp has tubes or transistors as long as a violin sounds like a violin and a piano like a piano. (although with this amp I could probably tell whether it was a Yamaha or Steinway) When I asked my girlfriend if she noticed a difference, she thought for a moment and then said, "it has a pulse". Coming from someone who knows none of the audiphile "lingo", she described the amp perfectly. This amp moves with the music. I find myself dancing across the room and tapping my feet while listening. I can tell, this has not been my experience with other amps. I really had an epiphany when I heard Miles play My Funny Valentine (a great recording on The Essential Miles). I played jazz upright bass in Boston and New York for many years, and I could practically smell the drinks and cigarette smoke. It is the closest I have ever come to being back in a Jazz club in 30 years. The sound of Trane's saxaphone was sultry and sexy, not a bit harsh.

Performance at low volumes - Another reviewer made it a point to highlight this quality and now I understand why. This amp sounds good at any volume. There may be an optimal volume for a given recording that closely recreates the mixed volume, however,few amps sound so musical and vibrant at low volumes. The Ayre is fun to turn down and listen to. Somehow it still evokes the sense of excitement and drive. This is a nice feature if for late-at-night listening sessions.

So this is a keeper. I can imagine upgrading speakers at some point and maybe getting a new DAC or transport at some point but this amp is staying. I suppose if money was no object, I would get the Ayre separates! Clearly Ayre knows how to reproduce music and I am looking forward to re-experiencing all of mine over the next months.

Great review. This integrated is a gem. I have compared it to higher priced gear, and it holds its own.
Couldn't agree more with your conclusions. I love this amp.
I was trying to make the decision whether to end my thirty year relationship with Quad. My local hi-end dealer lent me an AX7e for a week. That was ten days ago. I now own a K-5Xe and a V -5Xe.

I loved my Quads but when I heard the Ayre and had it in my home for a week, it became palpably clear what was missing in my music. It's the pianos, the Ayre pianos have it. The whole note from attack through the sustain and the decay - the whole note is there. Listen to Keith Jarrett's iconic Koln Concert. That piano rings on any on in the way that we know that pianos do.

These are amazing machines!
Hi Drew - thanks for your great review. I realize it's been several years, but wondering how the AX7e held up in your system. I also have a Monarchy NM24 DAC and am looking for a good integrated to go with it. Did the AX7e sound ok with the unbalanced outputs of the DAC? Or did you use a transformer? Thanks!
I'm using my AX7e with a pair of KEF LS50s.  Source is microRendu USB to an Ayre Codex with balanced input to the amp.  I really like the sound of that setup.  I'm twirling around the idea of selling my KX-5/20, VX-5/20, and KEF Ref 1s, replacing the microRendu/Codex with my QX-5 digital hub, and letting this be my primary system.  The AX7e currently sits atop a P5xe phonostage & C5xeMP, both with balanced connections to the amp.
I know that you would enjoy the AX-5/20 Integrated amp. I am strongly considering a purchase in the Fall to match my DX-5 spinner.
Happy Listening!
I recently added a Qx-5-Twenty to replace my ML 390S CD player as I went to streaming.
Thursday, I am finally getting my Roon Nucleus after a long wait.

The QX-5 is a game changer for me even as currently configured and should get even better when the system is completed this week.

This is the first Ayre product I have purchased and I am quite pleased.
