Maxmad,
I realized that this thread has been inactive for a while, but oh well.Are you still using AVVT in your Cary amp? I've been using the AVVT 32b SL for the last several weeks and honestly, this is a wonderful 300b. We have different amplifiers so just interested in your impressions. One of my Takatsukis failed (extremely rare per the company with 1, 000 pairs sold so far).Amtrans has been responsive and is sending a replacement pair under their warranty.
I really look forward to comparing the Takatsuki with the AVVT 32b SL.Physically these two 300b look nothing alike and very likely use different construction and materials. Yet both are clearly successful sonically.
According to Jac (Jac Music Germany) this model AVVT has a 40, 000 hour lifespan!
