A very fair review and I agree entirely with the remarks about sound quality. I have owned an LTA Z10e for about 6 months now and I look forward to every time I am going to use it. I have Dan Clark Voce ES, A-T W3000 anniversary dynamic phones and Zingali Overture 2 part horn loaded speakers which are at least 91dB efficient. Whichever outlet I use the results are very musically enjoyable, the tonal and dynamic qualities so involving. During the time I have owned it there has not been a moment when the LTA amp failed to engage and please me. It is a great all round product.
