I got my Topping TP20 from US a couple of weeks ago and was able to audition it today finally.
Paired it with the CA S30 but was not impressed. Tried with MA BR1 and it was awesome
hyeah:.
Also checked with the MA BX1 but did not notice any substantial improvement in SQ for the price difference or size. Due to the settings of the shelf where I plan to put the speakers, I cannot not go with rear ported speakers or those that are too big; the dimensions of the BR1 was ok, but it was rear ported.
Will check some options from Polk Audio tomorrow, they seem to have high sensitivity speakers that hopefully will pair well with the TP20.
I also wanted to check out JBL control 1, but the seem to be no longer in the Forum mall.
