Can my MC275 power speakers with 91db sensitivity


I am looking to buy some songs faber cremona speakers with the following specs:

SENSITIVITY
91 dB SPL (2,83 V/1m).

NOMINAL IMPEDANCE
4 ohm.

I have the most recent MC275. Would my amp have enough power?

It can but probably not optimally along the lines related by Al.

That's not to say it won't sound good or meet your needs/expectations, only that you have a good chance of doing better in terms of both volume sans clipping and balanced and clean bass response and lower distortion otherwise as well perhaps to the extent that matters if you become so inclined.

So you can look at these things from the perspective of ideal technical matches that maximize performance, ie the perspective of intelligent "audiophiles" for the most part, or from the perspective of does it sound "good" or "good enough". Improving usually comes at some cost.

So its very much the oft cited "your mileage may vary" type scenario.

If that bothers you, then probably better to seek out different speakers that are more efficient and tube amp friendly in general.

Al's speaker recommendations are good ones. I might toss in Triangle and many Focal/JM Lab speaker models as possibilities.

Even Magneplanars could work very well with a tube amp like that, especially if very high volumes are not a concern.

OHM is another line that is perhaps not as tube amp friendly as some, but offers good value and decent performance with a higher power tube amp.

Adding a powered sub or two and offloading the low bass to that opens up a lot of additional popular speakers choices. That's a popular option for many OHM owners that use tube amps in some cases (some might go sans sub)and also for most any good quality speaker, including SOnus Faber.

Also, most any good quality horn loaded high efficiency speaker (mid 90s db efficient or higher) would be very good technical matches for that amp. There are many very good makers of high efficiency horn loaded speakers out there these days. Take a look at Cathedral speakers out of Virginai for an example of good sounding horns I have heard that can be had for very modest cost.

Electrostatic speakers are another good option to consider if that kind of thing might float your boat.

So basically, there are ways to make that amp work very well indeed with most anything if done right.

Hope that helps.
I'm on board with Al/Atmasphere/Bifwynne and others regarding how impedance and phase angle are key factors to consider when choosing an amp to get best performance out of speakers.

Also that there are many shades of grey in between the extremes in regards to amp technology and design, and that as a result, it can be very hard to predict how good or not any particular combo really sounds, but it is not as hard to predict which combos have the best chances of working out optimally together from a technical perspective.

Also I believe that is is important for things to work out well from a technical perspective, however, that alone does not ensure enjoyment. Enjoyment is what it is all about in the end. Good technical execution can usually only help, but alone does not guarantee the desired outcome, which might be had many different ways.
