• AVI ADM9.1 Preview

    The ADM9.1s have finally made the journey across the Atlantic and arrived here at Computer Audiophile. At first glance the ADM9.1s look just like the ADM9s. Appearance is about the only thing the two models have in common. So far I have spent a few hours listening to both the ADM9s and 9.1s individually and in direct comparison to each other. I certainly won't go into much detail since this is just a preview of what's to come. However I will say if the 9.1s continue the perform as well as they have so far the little elves at AVI better get to work. They'll be building a lot of ADM9.1s. 

    Much more to come in a full review and direct comparison of the ADM9 and ADM9.1s. Here are the basic specs for the ADM9.1s.

    Technical Specifications

    Power amplifiers - High speed, linear, analogue bipolar, 75 wpc for the tweeters and 250 wpc for the bass drivers. Distortion typically better than 0.002% and dynamic range 120 dB.

    Crossovers - High quality 4th order discrete analogue.

    Preamplifier - High quality state of the art analogue preamplifier with two digital and one analogue input. Control is remote and volume settings are remembered for each separate input.

    DAC - Up to the minute 24/192, completely jitter free design.

    Bass driver - Very high power handling 6.5" paper cone drive unit with 1.5" voice coil and exceptionally broad bandwidth enabling phase perfect crossover at 3.4 kHz. Bass extension better than - 6dB @ 60Hz.

    Tweeter - 1" Silk Dome tweeter with -3 dB point of 28 kHz.

    System Amplitude response better than + or - 2 dB 100 Hz - 20 kHz.

    Max continuous SPL (both driven 1 m 100 hr rating) 108dB with 8dB Threshold.

      Hi Tony - Welcome to Computer Audiophile. The 9.1s have two optical (Toslink) inputs. It is my understanding that one coax input can replace one optical input via special order.

      They have two toslink and one analogue RCA.

      Come on Chris you are killing me. I had to wait months for my ADM9's to arrive as they spent time on a ship circling the globe, and I have been waiting for the 9.1s at least give us a few more impressions of the 9.1s.

      Hi<br />
      <br />
      I currently own a pair of ADM9.1's and they're wonderful. Sound amazing.<br />
      <br />
      However, I've read a couple of times on this website that some prefer a Mac Mini instead of a Squeezebox. The issue in this case is not the user interface but the sound itself. Some say that the Mac Mini sounds better through the digital input (toslink) than the Squeezebox (also through toslink). My question is: how can this be? How can 1-0-0-1-0-1-1-0-0-1' s sound better on a Mac than on a Squeezebox? Digital is digital, right?<br />
      <br />
      Can someone please explain this?

      Hi Maddox Kid Plus - Welcome to Computer Audiophile. This questions is discussed frequently and often turns into a pissing match. Fortunately this is a laid back site where everyone can give you their honest opinion without getting ridiculed. So, here is my opinion on this issue.<br />
      <br />
      Digital is not digital. If digital was digital every transport would sound the same. The sound differences come mainly from different implementations by each manufacturer including how jitter is managed.

      Well, I can finally stop hassling Ashley every day, chasing my ADM9.1s - they've arrived.!<br />
      Only a few hours into listening but I'm so happy - I'm yet to get them onto decent stands too.<br />
      <br />
      What a great listen; started out with the usual stuff before heading for the Linn website to download some studio master FLAC's. So far - WOW!<br />
      <br />
      Looking forward to reading your review Chris.<br />

      I, too, am a very satisfied AVI customer. I have the original ADM9's and Sub, bought a few months ago just as the 9.1's were being introduced. I have them running from a Macbook via the digital input and from an AVI CD player through the analogue inputs. Both sound great, but I am looking to move over entirely to the Mac as my sole source.<br />
      <br />
      Can you give me more details on these Linn FLAC's and how to download them-do you import them into itunes?<br />
      <br />

      Hey Phil,<br />
      <br />
      Looks like Chris got there first !<br />
      <br />
      I used his guide using the Max software. Worked a treat and the sound is awesome.<br />
      <br />
      Ashley at AVI recommended this site: http://www.gimell.com/<br />
      I've not tried any of the downloads yet - but am looking for one or two now whilst listening to a spot of Roxy Music ... <br />

      When will we see a review, Chris?

      I don't have a date for you unfortunately. I need to really spend the necessary time listening to them with different sources etc... This way the review may be more helpful and accurate.

      Well, at least what is your first impression on the speakers? Do they surprise and even surpass more expensive separates? <br />
      <br />
      Best regards

      I will say "surprised" is a good word to describe my first impression. In a good way of course.
