Help Tannoy XT6F with Primaluna
Question for Al - I think you have probably nailed the issue in your second-to -last paragraph. The question I have is - would it be possible to match the amp to the speakers via some type of custom built "matching transformer"? I did have an issue with an amp many many years ago and had a matching transformer custom built by a very knowledgeable guy that built transformers for a living Just trying to think of a solution for the OP - other than replacing the amp :-) Cheers |
Hi Steve (Williewonka), That’s a logical question, but I doubt that it would be a good solution in this case. While raising the load impedance seen by the amp with, for example, a set of Zeros, would ameliorate the effect I referred to, it would mean that the output tap of the amp would not be working into the load impedance it was designed for. Which I suspect would have adverse effects on both the distortion characteristics of the amp and on its output power capability. Also, the cost of the Zeros ($540 without enclosures or $1140 with enclosures) is perhaps a bit unreasonable in relation to the cost of the amplifier ($2199). And, finally, I note that subsequent to my post the OP reported that he is not even getting acceptable results with a solid state amp. So it seems clear that other issues are contributing to the problem, in addition to the effect I cited. Best regards, -- Al |
