I recently purchase a Wyred4Sound STi-1000 integrated amplifier. Thought I'd share my thoughts on this piece of kit (as somebody requested). The previous amplifier in my system was a NAD M2. The NAD M2 is an excellent integrated amplifier and has an extremely quiet noise floor. The M2 has great clarity and detail but remains very smooth sounding. The one thing that might not be strictly neutral with the M2 is the bass. The amp has fantastic bass, but I think it is just a smidge over done. In the past, I really enjoyed the fullness of the bass delivery, but when I purchase my latest speakers, PMC IB2s, they didn't need this help in the bass department. So I decided to try the Wyred4Sound integrated amp for two reasons. First, I wanted something with massive power because the IB2S can handle it and because I thought that would help control the woofers on the IB2S and give them the power to sound their best. Secondly, I happen to find a Wyred4Sound STi-1000 on the used market at a very attractive price. So I bought it. To be honest, I did not expect to like the amp. I've been using amps that are a bit more expensive so I didn't think this amp would be in that league but also, the amp just doesn't look very impressive (not a good indicator of sound quality I know, but it impacted my expectations). Well, I could not have been more wrong with my low expectations for this integrated amplifier. I turns out to have fabulous sound quality. Massive power that is palpable. Rock solid control of the big woofers on the IB2S speakers. Clean, quiet, and detailed sound without the harshness that sometimes is attributed to class D ampfliiers like this. Like many current class D amplfiers on the market the Wyred4Sound amps are based on the Bang&Olufson ICE power modules. But they are modified and coupled to Wyred's own prorietary input and output states. Also Wyred uses a very high quality stepped resistor volume control for the preamp section. The amp is very high quality for the price. I love that the amps generates very little heat and is small and light compared to any comparable class A/B amplifiers. The Wyred amp has done exactly what I was hoping for when I replace the NAD M2 (which I still highly recommend). The amp is a great match for these big PMC speakers.
