need some input on xr55 Panasonic setups

Hey,
I am new here, but have been scouting out these forums for a while. I tried the search function for xr55, but nothing came up, so I am just asking.

I recently purchased a new xr55 after reading some rave reviews about the sound for music / movies. I was intrigued by the reviews and thought i'd give it a shot in my new system.

Does anyone have any experience with this product on these forums? Also, what speakers would pair nicely with the panasonic xr55. A few i am thinking of...
1. Ascend Acoustics 170-SE (bookshelf), plus a subwoofer (i've heard good things about this combo)
2. Aperion Audio 533-T (tower) speakers (these look gorgeous, got a great review, and have a great return policy...i am just not sure how they would sound with the panny.)

any other thoughts?

Info: Room is fairly large - family room with natural tile floors, 12' ceilings, 12'x40' room (kitchen is adjacent).
THanks!

Re: need some input on xr55 Panasonic setups

The Panasonic class D amplifiers require a very stable eight Ohm load, no dip lower than six Ohms, to sound their best. As the impedance of the load rises or falls the sound quality of the amplifier will correspondingly shift. Higher impedance will typically give a dull sound with compressed dynamics and rolled off top end. Lowering the impedance gives a glassy hardness to the sound and compresses almost every aspect of sound quaity. Phase angle of the speaker should be kept to a minimum. Personally, I would suggest a single driver, full range speaker but they do not always suit the taste of someone listening to "loud" music or complex orchestration. There are a few designs available on line which employ a full range driver supplemented by a tweeter crossed at a higher than average frequency (5-10kHz) which give good results with the Panasonic amplifier. Buy a speaker with reasonably high sensitivity as the class D amplifiers tend to produce aluminum spit balls when driven into clipping.

Thanks for the reply, Jan

Anyone else have any speaker suggestions. Specifically, whether or not the speaker setups i suggested will sound good? Maybe other speakers that others have used successfully with this unit.

I've been researching this xr55 and some people love it, others hate it, but it is hard to get concrete answers on what people are using as speaker-setups when they listen to this thing...and what works with it.

For the record, i will be running a Comcast digital cable signal through it for TV sounds (via optical) and a DVD player for DVD-sound (via optical).

I am looking to spend 700 bucks or so on speakers. If the 2 speaker setup sounds great, sans the suvbwoofer, then that is great. Eventually, I'd want to upgrade to a full theatre setup.

Thanks in advance
Peace out

Re: need some input on xr55 Panasonic setups

I have an XR55. I too was intrigued by comments about the virtues of its sound. At first, I found the sound harsh and brittle, but after a few days it lost the harshness and brittleness for the most part. At very loud volumes it becomes very unpleasant.

I listen mostly to the XM radio service through a Polk device. For a slightly livelier sound I have the "re-master" setting turned on to the extended range setting. I do some listening to CD and keep the "re-master" effect engaged.

The speakers I have are a pair of Wharfedale Pacific Evolution 20(tweeter, 6.7" woofer) column style. I am sure that there are better speakers, but they suit me fine.

The only real question I have about the XR55 is that I wonder what 150-200 watts would sound like. However, Panasonic is keeping the XR5x at 100 watts.
