    I’ve ordered 2 IOM NCore Mono Amplifiers . The ordering process went very smoothly and communication about the delivery was very good.

    The combination of these amplifiers and my electrostatic speakers is suberb. All kinds of music are no problem for this amplifier which produces a clean sound with a wide sound image.

    The appearance and the finish is very nice. I’m very satisfied with new my amplifiers.

    I have 2 new IOM500 monoblocks with 12V trigger and both RCA and XLR outputs

    Process was very easy and homely
    I got in touch because I wanted monoblocks with VU displays in it and after a listening session and couple cups off coffee with a very nice and honest conversation I decided to order 2 brand new models of the 500series

    Picked them up a couple of weeks ago and because I am the first one to test the new model we decided to keep in touch
    After testing the amps I took them back to home and packed with new cables i was underway

    After connecting them I put them first to a test of sounds and let them play for at least 12 hours straight at about 40% of capacity ( got speakers that don’t mind that kind of power )

    Then i started listening with my own playlist on various streaming services and some vinyl
    At first I didn’t know what to expect because I only had heard my speakers on the power of my avr ( Yamaha RX-A2080 ) before that I couldn’t remember them because they are in the family for an odd 25 years ( they are MC-Systems M202 )
    I started with a couple of sting songs and noticed that every little detail was very crisp and powerful even on high volume ( -16 )
    After that I got to the dire straits and Bruce spring steen type of music and noticed that the low end was very powerful and I didn’t know that it was reachable with the speakers so I contacted the manufacturer and got the reply that they are very high sensitive speakers with an enormous thirst for power ( not that they sound bad with low wattages not at all)

    After the nostalgia I switched to a bit heavier music like deephouse and some techno I was very surprised how low and powerful it was well beyond the 40hz level

    I put them to some endurance tests aswell ( up to 6-7 hours non stop on 75% capacity )and noticed that they aren’t getting any warmer then my avr and streamer ( that for an fully sealed system is impressive )

    All and all I am very impressed and happy that I purchased the IOM500 monoblocks and can recommend them because they are powerful controlled and have a stylish black design in an small package

    I am even prepared to welcome people to listen to them and if logisticly possible with there own speakers

    My current set-up is
    Yamaha RX-A2080
    Auralic Altair G1
    2 x MC-Systems M202
    1x B&W HTM602S center
    2x B&W M1 surround
    1x Rel HT/1003 subwoofer

    2x IOM500 monoblocks
