B&K 307 vs. Denon 5800 Debate

Phyre3, Finally a reasonable explaination. Thank you!
So what if I bought the high end of the B&K amplifier line (the one with the same chassis as lower end ones) with all the channels... What is my upgrade path? I presume NONE
other than buy new.

Traditional "upgrade" companies upgrade the processors and do not ADD amplifiers to their products. Before home theater, there was never a need to upgrade your stereo to a "trieo?"... Whatever... three channel sound.

My whole point on this issue is that since HT is SO relatively new and formats are changing so often, a firmware upgrade may do nothing becuase in order to
enjoy your new firmware/format, you need additional
hardware to support it.

Just like your point of SACD "upgradability". Upgrading
my Receiver to be able to decode SACD will give me no benefit since my current sources DO NOT READ SACD. The media first must be read before it is decoded.

And... if you buy a SACD player.... guess what comes with it? A DECODER!!! I seriously doubt we'll be seeing SACD transports in the near future. But... who knows, this is a strange industry.

Bwhite,
You make some good points. If you are talking about upgrading a receiver to more channels then yes a firmware upgrade to a format of more channels may not be the best route. But there are other format upgrades besides adding channels.

Yes you are correct that you don't traditionally upgrade amplifiers but processors though many companies are making modular amps to accomodate more channels in the future.

SACD players do come with their own decoding so it may not be worth it for that but Dolby Prologic II is a different story. It is closer to a Discrete 5.1 than any other algorythm and is designed for music as well as music. I would love to hear my broadcasts and VCR tapes and some CDs in this format and from other reports it is going to be great. Of course you may say DD and DTS is better. Well yes but how much 2 channel stuff is out there that will sound great with this?

How about the rumored upgrade of DTS ES to DTS ES discrete. Now there is some real benefit to B&K upgrade program because for a smaller fee I can have my processor upgraded to a Discrete 6.1 system without droping 3K to get a new one. I believe Dolby and DTS have also released upgraded decoding for better performance and there is something else that would be nice.

But yes eventually the upgrade path will be used up and no longer worth doing which gives some of us a perfect excuse to buy new gear. But like I said in my preivous post I don't think your going to see that much more coming out in the way of new formats as the industry has seen a fair share and more than 8 speakers in a room is an impracticality for a great many people no matter how good it sounds. I do think there will be much more integration of the components and that could be the future of av components not adding more channels than 8. A 10.1 channel receiver would be huge and cost a ton if it was any good and a $1000 one would be cheap and probably sound bad so I don't think that the industry is going to jump onto that. I think they will spend more time improving their formats and probably Dolby will introduce a Discrete system as well which B&K should be upgradeable to but you never know for sure right?

Anyway more of my thoughts.

Marantz sr14ex sr18. Outclasses most gear mentioned here. 2 ch.  I own denon avr5805. Pioneer  Vsx59txi and above mentioned marantz.   The marantz is more detailed and smooth as silk.  I’ve done head to head comparison.  Marantz is so fluid it drips with perfection.  Denon and pioneer are nice and each have their own sound signature but only the marantz make the hair on my neck stand.   I tried using a modded adcom gfa555 with these pieces as the preamp with no satisfaction.  

Picked up Bellini audio analogue preamp with b&k ex442.  My marantz sr14ex still wins.  Although the b&k and bellanest no sound amazing
