TDA takes at least a week to start sounding good. It really goes off in the first week. Still improving 3 months down the line.

There a fantastic review of the SDA in June's edition of Hi-fi World. 7 pages.

To quote.............

"Supremely smooth and well balanced in every respect, this amplifier starkly shows what other solid-state does wrong. Brilliantly engineered, it's nothing less than an epoch-making audio product."  (5 globes and a £)

TDA is far superior to SDA, but as alanbeeb says, it's about system matching. May be worth looking at the rest of the system before dismissing the TacT gear, or as the Denmark half of TacT will be known in future 'Lyngdorf Audio'.

But of course, I'm biased. 

There is a new Lyngdorf Audio forum on Yahoo.
