Some amplifier questions

Tim,
Of course, all your suggestions are sensible and probably have been extremely helpful to Wemfan. I re-read the thread and I still don't see him mentioning HT. He's mentioned TV twice in the thread. He'll probably clarify - I mean - he has the Oppo 105 so why not watch movies in the bedroom!??

I think it may be a mistake to forego a center channel speaker given he has mentioned a few times how important dialogue is. I don't think relying on a phantom center is this case will be sufficient - especially if he he intends to watch 90% TV (and maybe movies) and 10% music.

As to his probable speaker choice - the KEF LS50 - I have not heard them, only read about them. Given his space limitations, those familiar with them, do you think they will work in his space? I am wondering if a speaker that isn't placement sensitive might merit consideration?

Tim and Finsup,

I did purchase a Parasound A31( I bet I did pay too much for it) which should be here Wednesday and I ordered an Oppo 105D and a pair of LS50 speakers last week. What I am missing are speaker stands, a center speaker and a sub which I will probably order over the next few weeks. I have changed racks so now I can accommodate the larger KEF center speaker which is what I will order if I go ahead with a center channel.

I will use this system primarily for TV but I am a musician so I will significantly up the percentage of music listening once I have a good system in place. However, I will probably never go to a 5.1 system as the head of my bed is against the wall and that is what I lay up against. I really think this system is all I am ever going to want in that room, anyway. I also have the same Panny television in two other rooms which will need my attention. One is the living room in which I want to do something above this system so this one I am learning on. The other bedroom is where we sleep and where my wife watches most of her television. It is a large room and all I have talked her into so far is a soundbar which really helped but is far from what I want in there. So far, she has been agreeable on my $2000-$4000 system (that has suddenly grown to 10) so I won't push for more until after a little time passes. :-)

You guys have all been very helpful, especially Tim, and I am considering every suggestion. I have a lot more equipment to buy so I am all ears and trying to learn. I am really looking forward to setting this thing up and I am sure I am going to have a lot of questions. Once this one is complete and I can give you my impressions I want to start in the living room which we use for 95% music and 5% television. It is a large room and I want it loud in there.

I will give continue to give updates as we go and ask for advice...lots of advice.... Thanks guys

Finsup and Wemfan,

"Tim,

I agree that all my suggestions are sensible, as are yours(although I'm sure you just forgot to include the adjective "extremely" in front of "sensible" as you surely intended). Just having some fun.

You're correct, I assumed he would be watching tv, as well as bluray movies, in his deluxe bedroom system and referred to the totality as HT in my prior posts.

"I think it may be a mistake to forego a center channel speaker given he has mentioned a few times how important dialogue is. I don't think relying on a phantom center is this case will be sufficient - especially if he intends to watch 90% TV (and maybe movies) and 10% music."

Yes, given Wemfan's statements, he will probably want to include a dedicated center channel speaker in his system. I would not recommend the use of a 'phantom center', either. I think he agrees and is planning on including a dedicated center and bought a rack that has a position for it.

"As to his probable speaker choice - the KEF LS50 - I have not heard them, only read about them. Given his space limitations, those familiar with them, do you think they will work in his space? I am wondering if a speaker that isn't placement sensitive might merit consideration?"

I have never listened to the KEF LS50s, either. I actually recommended earlier a different pair of speakers to Wemfan, the Golden Ear Triton towers, but he chose to buy the KEFs. I do not think that Wemfan made a bad choice. On the contrary, the more reviews and info I read about these speakers, the more I think Wemfan made a good choice with the LS50s.

All speakers, in my experience, are 'placement sensitive' and require some sort of trial and error experimental positioning to achieve optimum sq results.

Currently, I have only 2 concerns once Wemfan gets his chosen system up and running:

1. Will it have sufficient and the proper bass response?

The KEFs are highly rated and may deliver sufficient and well defined bass response all by themselves, especially considering this is a bedroom system that will not require prodigious amounts of bass. The good news, if Wemfan decides he wants increased bass performance, is that this can be easily incorporated later by adding an amplified subwoofer. This is a decision that needs to be addressed after system setup and assessment.

2. What speaker stands will Wemfan purchase?

The LS50s require a pair of good quality stands for setup positioning and optimum sq performance. The critical factors are the height and left and right positioning in relation to Wemfan's head/ears at his listening position, presumably laying in his bed. A 3rd factor to consider is the coupling/decoupling desired from the stands/speakers to the floor. I am not well versed on this subject since I prefer to use floor standing panel speakers, not monitors.

I agree with Finsup, it would be very helpful to hear from LS50 owners/users and others knowledgeable of these speakers at this point.

As I currently understand it, Wemfan has the hdtv, Oppo 105,3-shelf rack and the KEFs are ordered and on their way. That leaves 2 components for Wemfan to decide on and order: the stands and an amplifier.

I've been looking into possible stands and would suggest Wemfan start by looking at Sound Anchor and Sanus stands. I found Google searches such as "Sanus(or Sound Anchor) stands for KEF LS50 speakers" works well, either pressing 'enter' for general results or clicking on 'images' if you want a visual of options.

You're almost there Wemfan,
Tim

I am getting closer. I ordered the stands from Soundanchors today. I chose the single post adjustable stand. You can angle the speaker as well as adjust its height.

To make the system complete I still need a center speaker and a sub. According to KEF I should go with an R series center so I think I will go with the R-600 for $1499. I know some subs have been suggested but I haven't turned my attention that way, yet. I need to wait a few weeks before spending more money.

I do want to make a sub choice soon, though.

Wemfan,

So, you have a new rack on order with a larger center speaker position and you bought the Parasound A31 3-ch amp.

I think you just need a pair of good stands for the LS50s, right?

Each LS50 weighs 16lbs and is 12"high x 8"wide x 11"deep. The stand chosen needs to be atleast these dimensions to be secure. The middle of the LS50's driver contains the tweeter(high frequency driver). Ideally, your ears, when laying on your bed at your usual viewing/listening position, should be equal to or slightly above the tweeters.

I've looked at a few stands and found 4 possibilities so far:

1. Sanus SFC22 Steel foundations steel base center stands $160ea/$320pr on AMAZON Top Plate =12"W X 15"D HEIGHT=22" These have spikes for carpet or Neoprene soft feet for hard floors. These are actually center channel stands turned sideways for secure LS50 placement. This should not cause any sonic issues but you need to see them to confirm cosmetic suitability.

2. Sound Anchor Custom stands $800/PR 30" High and weigh 75lbs each (LS50's weigh 16lbs ea.) These are Sound Anchor's custom stands designed specifically for the LS50speakers. They are expensive but give the speakers a very solid foundation. (321)724-1237 or contact by email at [email protected]. TOP PLATE=?

3. Custom Design FS104 Signature Stands $350/pair. These are only available on Amazon in the U.K., afaik. These are good looking but also unique looking in black or chrome with optional top plate sizes to fit the LS50s. They have a large,thick and circular center support column with 4 much thinner support colums at the corners for added support. I think these in black would give a cool, cohesive look with the black LS50s. They're also less than half the price of the Sound Anchors. Only downsize may be shipping charges to the U.S. which I didn't check.

4. Argosy Classic speaker stands 36"high(42" for $10 more) and weigh 60lbs each $160/pair on sale now; this is a great price for 2 sturdy, good looking stands that would work well with the LS50s. Basically a Sound Anchor type foundation at a very low bargain price(hint, hint). Top plate is 12" x 12", bottom plate is 16" x 16". Only possible downside to these is 2" of excess top plate room will be visible on each side of the LS50;no big deal to me, when saving $640 a pair, but you may differ. www.sweetwater.com. These are a very good deal right now but make sure you like their looks; I do but looks are subjective. I would buy soon if you like these since they may go fast at this price.

So you need to do the following next:

Lay on your bed in your usual position (head against your headboard you said)and measure the distance from the floor to the middle of your ears.

Only consider stands that are equal to, or slightly below this measurement; as in lower by 1-2 inches tops.

This is not a complete list of all your options, just the ones I've found thus far. Once you find sturdy stands at the right height, your choice will probably come dwn to cosmetics and price.

Good luck on the homestretch,
Tim
