Xilin,
Welcome to the fold, and thank-you for your compliments.
From the bottom up;
Monster Power HTPS 7000 Reference Power Source, this unit provides a source of clean filtered power surge protection.
Denon AVR5800 which has now been upgraded to the 5803, I choose this unit based on reviews from other owners and from reviews in a number of HT magazines, the other considerations before buying this model was the Yamaha RXV1000 and the Marantz SR14EX.
Sony CDP-CX450 400 Disc CD Changer x 2, I purchased 2 of these units because I could daisy chain them together as a master and slave, This allows one to play a CD while the other selects the next track; they then cross fade from one player to the other with no delay or breaks in the music.
Denon DVD3800 this replaces the JVC 721 that is in that picture.
Pioneer PD-V10G, this unit I bought for my teenage daughter, she is a singer and has a number of CD karaoke discs that she uses for practice. (Grandma seems to like to get in on the act too. If they start line dancing out it goes!
)
Motorola Digital Cable unit
JVC HRS4800, No particular reason for this unit, has all the features I need in a VCR that hardly get used.
Yamaha KXW421 Tape Deck, Again no particular reason for this unit, I bought it when I bought my first HT receiver a Yamaha 995 about 2 years ago.
PVR5100 Satellite Decoder; the PVR means Personal Video Recorder, it records digitally direct from the satellite.
Direct TV Satellite Decoder (this has now been removed to make room for a Marantz SA8260 SACD Player that I have ordered) the jury is still out on this one, I picked the Marantz based on reputation but I have not heard this unit other then in a dealers shop. The reviews look good so I hopeful it turns out to be a good purchase.
As for the speakers I am using all Axioms, M80 mains, VP150 center channel, QS8 surrounds, 2 VP150’s for rear effects, 2 EP175 subs and 1 EP350 sub. I choose Axiom based on several factors. I had heard that they were a great speaker and wonderful value for the money. I started looking in on the message boards and reading the posts of users like JohnK and Chesseroo, and many other's too numerous to name here. All seem to share a common thread. They all loved these speakers, I began to look around at different speakers, JM Labs, Boston Acoustics, Martin Logan’ NHT ….etc, etc. Then I came across a shop that had Axioms setup in a demo room. We sat down and began to play all kinds of movies and different music tracks. I was honestly blown away I kept looking at the price list because I could not believe that these sounded so good for the price that was being asked for. I was sold, I mean I how could I justify spending in some cases 2-3 times the price for speakers that did not to me sound any better then what I was listening too!
My advice is spend some time in the forums read, read, read all that you can, and ask questions. There are a lot of really good people on this site with a wealth of knowledge that would be more then happy to share their experiences with you, and answer any questions you have.
Too everyone else my apologies for the long post.
Regards
John
