Dynaudio focus 360

Ok,

I thought you meant listening to certain recordings and how your system performed in different area’s.

To address where did I get 350 watts,I got that by reading many posts on here.

I went back and read every post on the dynaudio focus 360’s I could find.

Many said these speakers need high currant,and while I agree that sounds like over kill,I also talked to someone at dynaudio and they said they have heard back from customers that these speakers like 200-300 watts per channel.

I have heard several conrad johnson tube amps and really liked them.

I know solid state is different but everyone that reviewed these have said there are excellent.

One other thing was the output impedance of my Mac mx110 is 10k,and macintosh recommends a input impedance of at least 100k on any amp you use with it.

There aren’t many solid state amps with that high of a input impedance.

Particularly in the under 5000 range.

I would be glad to hear what amps you think might work well with these speakers.

I was going to go with the Pass labs X250.5. But the input impedance is only 20/30 kohms.

I was told by a couple of audio shops this would not be a good match.

I’am starting to like these speakers even with the Adcom amp now that I have moved them closer to the wall and plugged the back ports with the foam inserts,but of course I know they would probably sound much better with a better amp.

Thanks

@twangy57 thank you for your response. I obviously read your meaning incorrectly. I hope everything works out for you. Music listening is awesome for many of us, so I always wish the best. As far as stuffing foam in the ports on the 360s, I never heard them that way, but my feeling and experience is that they were designed as a ported box and therefore would sound best this way, at least the way Dynaudio intended with the design. Just have to dial them in within the room, which can take a while. My best, MrD.

I know,I really don't like the idea of restricting the output,but they do supply these with the speakers.

I think they suggest using them when you don't have enough room to move them out far enough,and your getting muddy bass.

I will reevaluate this when I get my new amp.

Thanks for your help.

OP, FWIW, I think your goals in getting and setting up your system may be based on a misconception about what it’s all about. The goal is to set up a system that accurately reproduces the sounds as they are recorded by an engineer in a studio (or live for that matter). Recording wise you get just that. The recording engineer places the mic’s and puts down tracks for each mic. Then he mixes them to reproduce his recording. Then this gets put on a disc or tape, etc. Then you buy it take it home and play it on your system. He did not design/set up your system so is not responsible for what you actually hear. All very obvious, yes?

Now most of your recordings are not made by the same engineers, different engineers, different musical sounding recordings, even with the same music. 

In a well matched and set up system you get to hear the recorded music exactly as it exists on the disc. 

When I look at your original post I can’t begin to understand where you have heard that music, as recorded, and find such divergence in the sound made by the system depending on the type of music you are listening to. IMO if you set up your system so that you hear one type of music as you want it to sound, without regard to the actual music on the disc, you will alter the sound when you play different types of music, for better or worse.

I would suggest that you rethink your expectations of your systems performance based on its absolute audio performance not your present expectations of how it should sound with one particular type of music. 

FWIW I doubt that the amp you have purchased (?) will solve your issues, hope that it does, just doubt it. FWIW, being able to match impedances is important but I don’t think that that issue alone will make the difference you seek. It can make a tonal change for sure and the 10K output of your preamp is unusually high yet resolve your audio issues, I doubt it. 

Hope things work out for you.

I can appreciate where you are coming from.

I grew up playing guitar since I was 12 years old,and I’am 67 now.

I don’t think I conveyed my expectations very well.

I was having problems with these speakers recreating the volume of the guitar in the mix of some rock recordings that I have listened to for 50 years.They just sounded neutered and to smooth.

I also understand what you mean by creating a more versatile system that can play most types of music well.

If I’am understanding what you are saying,don’t build a system striving to make some poorly engineered recording sound good,at the expense of all the excellent recordings out there.

If I have that right ,I agree with that.

Since the speaker location adjustments things are sounding better,and I have been enjoying listening for past the few hours.

The guitars are sounding like guitars.I listened to Who’s Next and it was really good.

Vocals are sounding better also,not dropping way down when the singer uses a softer delivery

I’am must admit,I was surprised  just how much difference it made by moving the speakers about 4 inches in closer to the front wall.

As the far as which amp to match with the mx110,I almost wish I would have just bought the speakers first,but I had already bought the preamp before getting on here.So I will keep looking,but at least this set up is sounding better to me now.

Thanks

@twangy57 , did you hear this problem through your Polk Monitor 10s? Although I was a horn guy (still am), I admired many Polk speakers and have had quite a few floor standers by them, including the 10s, in my rotations. I found every model to be able to play at a satisfying listening level, with all types of music. They can handle loud; I am talking about the models manufactured before they went overseas for build, as the 10s. However, I do understand why you changed from them and, did well. Keep in mind, that the 360s reveal a good amount of detail, so you might hear some weaknesses in the recordings themselves. Many listeners only listen to "the finer engineered recordings", and I can understand why. You experienced this in your original post. I would not be surprised if you start listening more and more to these quality recordings. Everyone loves music, but to only a small number of us (relatively to the rest of the world), this is a characteristic of being an audiophile.  Last note. IME, most classic rock is not recorded well, so you may hear things in the recordings...use of compression, equalization etc., which becomes obvious once you reach a level of transparency. My truth that I believe, is for bad recordings, listen to the musicians "play" and forget everything else. I feel the same way about great recordings too (1st and foremost, it is all about composition and musicianship), but when one of these recordings is playing on your system, you understand why you spent the money upgrading. It is amazing how recordings can sound so good through the home system. You will have a lot of fun with the CJ 350 (I liked it the few times I listened with it in a friend's system). MrD.
