thanks, Shadorne, very useful. I may have a go at this kind of tuning a bit later.
The level of gear you now have means that your next big improvement in sound quality will likely be driven by your tuning, placement and room acoustics. This means that that it may be well worth your while investigating some of this - ultimately, selecting your next home may be driven by the room you can find in order to dedicate to music/HT. The room is at least half of the overall equation.
For example, I saw photos of your centre speaker on a TV rack. Firstly, the center was not at the same height as the L and R mains mid range and tweeter. Secondly, the rack will result in quite bad edge diffraction (this may ruin the imaging or collapse sounds to the centre speaker). Thirdly, I am not keen on centre speakers with two midranges (or any speaker with two mids) as this will cause some lobes (comb filtering) in the response. The ideal centre is an identical speaker - if you don't have that then "phantom" centre is, IMHO, the best compromise for most domestic settings. The ideal TV screen is an audio transparent screen with identical L R and C speakers placed behind it. SeymourAV and several other companies make audio transparent screens (down only a 1 db or so in the treble) that roll down. Given that the price of projectors has come down enormously in recent years it may be worth investigating.
Shadorne, all you say is true and thanks for advice again, but things like identical centre speaker, projector, acoustically transparent screen etc. are only in my dreams and not in any short-term plan in reality. My main interest is stereo music, so I do not plan to invest much time or money into multichannel kit. with stereo, the next thing to look at is positioning of sub and maybe room response analysis and tuning. although in rented flat there is only so much oyu can do...
"Dream system Yes, Oh Maybe one day..."
Of course, my comments were towards your dream - nobody gets there in a month or even a year... for many it may take as much as 25 years to get there - some never get there and end up stuck at an intermediate gear swapping merry-go-round that never ends (collecting gear becomes the hobby rather than great sound). You are well on your way though and my only point was that the room/placement plays such a big role that it will help now to keep these aspects in perspective rather than spinning your tires stuck in the merry-go-round of gear swapping minor tweaks (like so many poor addicted audiophiles tend to do....nirvana always being the next preamp or next DAC or next....and on and on and on)
When Nirvana is the next CD or Blu-Ray or album...not your next piece of hardware.....then you are there.
re room correction for bass, what do you think of Antimode 8033. On paper it seems to offer level and phase(? or just take rt into account for additinal level correction?) equalisation and self calibrates... inexpensive, too...
do you have any expereicne of it? it seems to get good reveiws and I ahve seen one or tow positive user reports...
Sorry no experience with that. Though I see that Kalman Rubinson likes it. As far as I can tell Kal is a straight shooter and one of the few extremely knowledgeable reviewers in the industry. I think you can trust that this is great product for those who do not want to mess with the physics of designing filters and dialing them into a PEQ and spending days running tests to iterate towards a desired response - it seems that this product takes the science, effort and frustration out of the approach that I suggested and gets you most of the way there in one easy step.
Of course, it may not give you as much insight into your room and speaker placement as making your own complex set of measurements will, however, it will smooth your in room sub response in a matter of minutes. If you look my virtual system on Audiogon you'll see that in room raw response for an individual speaker can be interesting, ugly and quite revealing!
I am checkng with the manufacturer of 8033 - the connection is far from straightforward in my case... it needs an 2 rca to 1 RCA mixer on the input and then two opposite phase RCA into one balanced XLR on teh out...
Excuse my ignorance Shadorne but how do we create a 'phantom' centre in a domestic setting.
I know of one way - processors/receivers sometimes have a dsp mode where they create the effect of the sound coming from the middle while in fact being reproduced by L and R speakers, callled 'phantom centre' mode.
Yes as almaataKZ added, I mean "Phantom Centre" mode from a DSP. It simply takes the centre chanel info and adds it to the L&R channel as a mono signal.It works perfectly provided you are sitting perfectly centered. It will actually sound better than a centre speaker that is off axis (different height) from the L & R Mains. Three identical mains speaker L, R and C is optimal but the problem is the TV which is in the way. Hence the use of audio transparent screens being the best approach overall with identical front set of speakers - like they do at the cinema.
This is all very interesting.Are there any recommended DSP's for 2 channel or 3 with the added centre that are popular?
I'd recommend you start another thread. It would be unfair to hijack this thread. I believe there are a great many excellent DSP's out there. I'd recommend Anthem D2 but purely out of personal experience with their AVM20 but there are too many great sounding options to pretend that there is a "best". Just look for features you desire (like passthrough for serious 2 channel listening, number of XLR outputs and programmability, bass management etc.)
Of couse your absolutely right, i didn't want to hijack the thread i was just very interested in what was being said so my apologies and thank you.
OK, looks like I am about to move into the final stage of the upgrades - the new receiver. I have settled on the model - Marantz SR5005 which is just out. The criteria was simple - the chapest one with all hd sound formats, pre-outs and "clean' face and discrete remote codes available.
I found the full remote codes set here: http://us.marantz.com/689.asp?category=AV&model=SR5005&go.x=14&go.y=9 (European site has nothing... why is this quite often the case that US sites have more useful stuff on them than UK?...)
I am now calling around dealers to check the price and availability.
Good luck with that one...
Thanks! What would you call a lucky price on that one?
it is just out so I am not expecting big discounts...
