I had the pleasure of visiting Derby yesterday on a wet rainy day from London and decided to pop into Musicraft to take a look at the ATC SIA 2-150. I got to meet Rick the owner(who is nice gentleman) once again who had the unit in stock. I was anxious to go to a specialist to have a first hand audition at the SIA 2-150( Stereo Integrated Amplifier,2 for the amount of channels and 150 being the power ouput per watts)
The SIA 2-150 was switched of when i popped in so after chatting with Rick for a bit it was turned on. The case work looks better than the previous version which includes aluminium front panels which offers minimum control.There is a large knob for volume control,the other for input selector with a central light which turns green when lit and goes on red when in standby mode.
This amplifier has a massive power supply which delivers class A/B output of 150-watts, a greater fraction being class A.
The ATC amplifier was hooked to the Monitor audio PL100. As time went on the amplifier got warm the sound just got better due to the neutrality of the electronics.It allowed the speakers to perform admirably and Rick was on hand to answer all the questions i threw at him.
Thw SIA 2-150 produced a clean sound which was not aggressive but had bite. It made the PL100 deliver a balanced result due to the dynamics of the electronics. This amplifier has a wide and deep sound stage with good control of the bass. The delivery of the clean sound reproduction by the SIA2 -150 has to be matched mostly by a pre/power amplification.For its retro look similar to my Yamaha AS2000 its a major player in the amplifier market; a true renaissance amplifier.
The end result is a 5 star unit that will last for years to come with a whooping 6 year warranty.
Many thanks to Rick for the the demo and i hope i can one day purchase this unit.
