McCormack DNA .5? Do I need more power?


Hi. I have been thinking about picking up a used McCormack DNA 0.5, which I may upgrade in the future. Will it be powerful enough at only 100w? I am currently using a B&K Reference 4420 (225wpc) and while it sounds good, I am sure I will get better sound out of the McCormack, especially once upgraded. My speakers are 91db, pretty efficient, but they have a big 10" driver along with a 6.5" driver, 1" driver, and tweeter, so I don't want to under-power them. Manufacturer recommends no less than 30w. I don't play real loud (no higher than 10 o'clock, which is plenty), but I don't want the lows to be muddled by a lack of power. What do you think?

Hi: Yes, I really like the McCormack DNA 0.5 / KEF 104.2 combo. I've owned 3 pairs of 104s over the years. I really love that speaker. Even after I moved on to other speakers, whenever I've run into a good deal (deal that cannot be refused) on a set of KEF 104.2s, I've bought them.

I am also a fan of the DNA series of McCormack amps... particularly the 0.5. I've also owned several iterations of these over the years. Currently, I am using McCormack Mono Blocks that started out and .5's as well as I am using a DNA 0.5 Ultra Platinum Upgrade in another system.

I think that you'll find the DNA 0.5 is more than adequate to run the KEFs. As a matter of fact, I found it superb. Consequently, I sold my last pair of 104s to a nephew, who is driving them with a 0.5 Deluxe!

I am still a lover of the KEF 104.2s, but currently I am using Dunlavy towers. I also use a set of stand mounted Acoustic Zen Adagio Jr speakers, which in exception for a ribbon tweeter, are not too dissimilar to the 104.2s in their conception and design configuration.

Hope this helps.
Hi Jedinite24: I have two pairs of Dunlavy speakers: SC-II & SC-III. They sound very different from each other in my opinion. I like them both fine. Both models image superbly. The IIs are 2-way and are very dynamic; the IIIs are 3-way and are a bit more hi-fi sounding but have a broader soundstage and give a fuller total presentation from top to bottom. Both models like power!

The Adagio Jr speakers do not have an internal woofer like the 104.2s down firing driver. However, the Adagios are also ported, but the port is in the rear. Even the Jr's move a lot of air and the bass response is a bit lower than the 104s. My experience is that placement of the Adagios is really critical and they are more demanding in placement than the 104.2s.

Best regards.
