Tumigil ka Jen.. Ikaw IDOL ko.. pero bago lahat.. Ikaw ang Audiophile Guru having experienced very High End stuff, sagutin mo tanong ko sa taas nito he he he
Sinagot ko na...
Honestly,you don't need high-powered amps/power amps for your speakers...I am using a 10WPC integrated amplifier and it fills my 20sqm room with music, regardless if it is Diana Krall or Steve Tyler...
Your advantage is that you have tons of choices since your speakers are highly efficient.
If you're happy with the NAD-NAD combo, you can retain...but if you're looking for a "different flavor", hybrid or pure tube is a good route for you...
Try to borrow a Line Magnetic 6550 Integrated Amp...I am sure you'll be happy with this...I have used this amp briefly with the DeCapos and I was happy...BUT IMHO Class A amplifiers, though running hotter and warmer perfectly mates with the DeCapos which you also have...
I have recommended the above amps as I have heard them paired actually with the DeCapos so I am recommending based on experience and not just via technical matching, etc.
The DeCapos sound best with AN, Leben, Rogers...
