Towards the end of the very nice VC Audio Labs MB-45 KT120 Monoblock Power Amplifier review, Michael Fremer dropped the iTube into the US$10k setup and it seems like he enjoyed what happened next:
“So I took the amps upstairs to my home theater that uses a pair of excellent Sonics by Joachim Gerhard Amerigo speakers (the brand name was subsequently changed to Spiral Groove and later to Canalis). These are/were $8000 3-way floor standers with relatively low 85dB efficiency. Add the Oddwatt MB-45s and the iFi iTube and you’re at around $10,000………Holy shit! The combination was like “what more could one want”? The iTube sufficiently (but just subtly) softened the overall sound to produce some of the best sound I’ve heard yet from those speakers. There was an ideal synergy between the iTube and the amps. The volume was almost up all the way but I was playing it loud into a fairly large room. The speakers are usually powered by 200 watts per channel of a 5 channel John Curl designed Parasound A-51 amp that’s very good sounding but these tube amps produced tube amp oomph and spaciousness while locking down those woofers.”
Thanks Analog Planet. Try the iPhono+iTube = baby PH-77!
