Thank you for response. I genuinely appreciate your comments and am glad to receive yet more validation of my choices. Upon visiting your web site as I frequently do, I saw a brief reference to your new TS33 model. I further saw the briefest of comments here but wondered when more information may be available. As mentioned, I have definately decided on purchasing the Zen amp and it would appear that your new model is designed to be a perfect match. I can only guess that given the Zens popularity, you can justify such a custom design. Can you elaborate on why you have designed it as you have? I do not profess to be as knowledgeable as are most of the members here but would like to educate mytself further so that I might understand and appreciate its construction. Thank you again and keep up the stellar work.
