Define power hungry...B&W speakers


I need to know what is important in amplification to power my B&W CDM 1NT's. Rated from 50-125 I believe. How much minimum power is necessary, damping factor, etc. What specs are important to me?
Thank you!

Tntate,

the power ampselection will depend upon tubed or solid-state. Over the years, I have heard many, many power amps n the various B&W speakers.

The newest Conrad Johnson Classic 60 is more than enough to drive at concert levels. On the SS side, Classe' , Mark Levinson, Rotel and Bryston all sound excellent as well.

Most importantly, which brand(s) of cables/power cords are you planning to use?

Keep me posted and Happy Listening!
The Musical Fidelity and Classe' brands keep coming up in my research, also Creek and Naim. I have not even considered special cables, power cords etc. I think I prefer a integrated amp to keep costs down. But again, trying to figure out specs to create a short list.

Thanks again!
I know exactly what you are looking for when you're asking for amp specs that you can use to make a decision. It definitely makes sense, but it's not going to happen. I'll give you a couple of examples of why that is. One of the more popular specs when it comes to power amps is thd. The designer for brand A may say that for 100 watts into 8 ohms, 2% thd is acceptable amount of distortion. If you give the same exact amp to Company B to rate its power, they may say that 2% is too much distortion for a 100 watt amp into 8 ohms. Maybe they feel anything above 1% is not acceptable. So if that's the case, company B may rate the amp at 75 watts instead. Or they could go the other way and say 3% is OK and give the amp a higher power rating like 125 watts. That's what I'm talking about when I say there's no standard. It explains why you can go into Best Buy and get a 100 watt/channel for $200, and then find a high end company that's selling a 100 watt/channel amp for thousands of dollars.

Another example is what makes up a watt. Watts are volts x amps. 10 amps and 10 volts is 100 watts. 50 volts and 2 amps is 100 watts. 20 volts and 5 amps is 100 watts. You get the picture.

Of course, there's more examples than what I list here. So if you're now thinking, what are you going to do as far as picking an amp? You need a way to go beyond the limitations you now find yourself in with regards to specs. The way you do that is by listening to whatever amps you are considering. Audio a very hands on. You need to listen to as many different components as you can. As you gain experience over time, it gets easier.

Looking at your system, the B&W's are not big floor standing speakers, and your room is not that big either. You really won't have any trouble finding an amp that will work for you. I would be more concerned with sound quality than watts. Also, you mentioned above that B&W recommends a high current amp, and they don't do a good job of defining exactly what that is. Its expected that you'll be working with a dealer that can help you make a selection. Speaker companies usually recommend a high current/powerful amp because they want their speakers to sound good. If you go in under powered, sound quality will suffer. And if that happens, there's always the chance you'll blame the poor sound quality on the speakers, and not the amp.
Thanks ZD542. I appreciate you taking the time to explain, it does make sense. My hope was to have a firm base of specs as I will probably buy used from this site. Without the ability to demo the gear its hard to make the best decision. I do know in the end that this all comes down to my room, my gear, and my own ears.

Thank you!

Any other thoughts out there?
Here's one more example for you that may help in your selection. You picked your B&W's for a reason. On paper, your CDM 1NT's look like countless other small speakers. You can find another pair of speakers of a similar design and specs, and for much less than what you spent on them. The reason you went for the B&W's is because you like the way they sound. You took the necessary step, and crossed over from the objective to the subjective. If you didn't do that, you couldn't justify the purchase. It's the same thing with any other component. If you set some goals as to what you expect from a new amp or integrated amp as far as sound quality, it will be a great help. You can still make a mistake, but you lower the chances. Try not to worry too much about the specs. I think you easily have the ability to make a sensible choice as to how powerful an amp you need. If you're not sure, just post what ever amp you are considering, and someone here should be able to tell you if it will drive your speakers, or not.

One last thing. Don't get sucked into the cable trap. Cables do make a difference, but so many people put way too much money into cables when it could have been used to buy better components. Not only that, but if you get good components and match them well, cable choice is very easy.
