Some amplifier questions


I plan to set up a sound system for my bedroom. The room is 16'x14'. I have a 65" Panasonic TV at the 14' end of the room. I want to have a center, sub and two front speakers. Should I be looking for a 3 channel amp or will a 5 channel work fine even though I won't be using all 5 channels? The system will be for 90% television and 10% music. What should I be looking for in a receiver? How many watts, features? What price range? The room is so small I can't listen to music very loudly but I don't want to be under powered. Some amp suggestions would be helpful. Thanks.

Wemfan,

Ok, it sounds like you have made some decisions:

You have a rack ordered with 3 shelf positions that will hold a yet to be determined center spkr, the Oppo 105 and a yet to be determined amp or a/v receiver. I'm not certain, but it sounds like the rack will also accommodate your 65" plasma either setting atop or attached to some built in structure.

Soix has raised some good points that deserve addressing:

1. Cost- Couldn't you just use an a/v receiver, with Audyssey or other room control capacity, along with a left, center and right speakers and possible sub?

The short answer is yes, you could, and this would give you sound quality far beyond your Panasonic's internal speakers and would be the least expensive option. However, I (and I think Rlwainwright and Dbphd, too) thought you were willing to pay more for sound quality a few steps beyond mass market consumer electronics and speakers, which is why we suggested higher end solutions.

Given your situation, sound goals and budget, your decision to buy the Oppo 105 is an excellent choice/solution. This unit has features that I'm not sure Soix is aware of:

It eliminates the need for an a/v receiver since it can be used as a limited input preamp (that works well for your requirements), surround sound processor for 3.1 to 7.1 configuration as well as high quality audio/video processors and dacs for music, movies and ota, cable and satellite hdtv. All you need to add is the amplifier and speakers.

It is true the Oppo lacks the sophisticated room correction software (Audyssey,etc) that some newer a/v receivers have but it does have a more basic speaker setup capacity that I think is ample for your purposes using a 3.0 or 3.1 setup. The Oppo's speaker configuration menu has a test tone generator that lets you balance your speakers manually by ear. You initially enter the distance in feet that your spkrs(l,c, r and sub) are from your listening position. If the system's algorithm settings are not to your liking, you can adjust each spkrs level up or down until you achieve the most balanced results to your ears.

The Oppo, along with a high quality 3-channel amp, likely gives you audio performance beyond almost any a/v receiver and light yrs ahead of the sound you currently have.

2. Equipment-Couldn't you just buy a simple setup consisting of a left, center and right speakers with a sub (like Axiom spkrs with a SVC sub)?

Again, the answer is yes you could. It all comes down to your budget and sound quality goals. Dbphd, Rlwainwright and I all offered options that are, admittedly, on the hi-end of the sound quality and cost spectrum that may be better suited to someone's main a/v system than a bedroom setup.

Are our suggestions 'overkill' and Soix's suggestion more appropriate and reasonable? Absolutely, but its your money and you just need to decide how much better sound is worth to you and how much your willing to spend. Only you, of course, can answer this.

You do have lots of options.

Have fun and enjoy the search,

Wemfan,

Two points to consider:

(1) If your LR speakers image well, you may not need a center channel. Reviews suggest the KEF LS50 image exceptionally well, but other speakers also image well. I removed our center channel, because the big KEF Reference 107/2s image so well a center channel is redundant.

(2) Low frequencies are most critical for room correction, and you might be able to find something like the Velodyne SMS-1 bass manager used at a good price. I've long used an SMS-1 to control a pair of HGS-15s, and I recently bought a pair of SMS-1s for $450.

Another option to consider is pairing an Oppo with active speakers such as the KRK VXT8.
Yesterday the audio rack arrived so I measured it and the space is 7'x20" where the center channel will sit. I am a little afraid to not have a center speaker as Dbphd suggests because I am having some trouble understanding some dialogue and that is one of the main problems I want to overcome. I installed a speaker bar in another bedroom with the same model television and it really cleared up the dialog for me so I am thinking I definitely want a center speaker since I will be mostly listening to television on this system.

I have been fighting a cold all week so I haven't been researching my options but early next week I plan to order the Oppo then make some decisions on the speakers and amplifier. I tend to always upgrade and really hate it when I go too cheap so I may up the amplifier quality some. i guess I need to decide on speakers first then I will post back here and you guys can help me make a good decision on an amplifier. The KEF LS50 speakers look really good but I also really like the idea of the sub being in the Goldenear cabinets, too.

I plan to restart my research on Monday and look up the new suggestions and go from there. I really appreciate all of the help. I am looking up and carefully considering every suggestion. Like anybody I want a good system at a fair price so I am reading and rereading the suggestions. I will keep you guys updated as I go along. Thanks...
Wemfan,

When you get the Oppo and before you commit to a center channel, try setting the center speaker to off in the Oppo set up menu so all dialog is apportioned to the LR speakers. The ability of the LR speakers to image well will have a strong effect on dialog intelligibility. The Stereophile sampler and test cd can be helpful in judging imaging. Well set up speakers should be able to generate a strong centered image.
