Question on SDA SRS...

Every time i see a set of SDA SRS speakers for sale...I go YES..i really want those...LOL

Now again there is a set for sale on Ebay..the price in not over the top..but the shipping could kill you.

BUT..the other major problem i see with these is POWER. I have an Onkyo M-504...works great for my SDA 1C's..but get the feeling this is bottom line to run the SRS. Is there a single power amp (common ground) that will run these speakers correctly?? Or you really need separate amps, then deal with the ground issue??



I would have to sell off all my speakers (SDA1 C's included) to get the SRS's..but if i have to throw another 2K at power for them...then far out of my pocket book, and i should just stick with my 1c's and be happy...LOL

    I would be more worried about the shipping than anything. You could use that amp as long as you don't go crazy with the levels. You know I got a pair of 1C last year at this time and I was thinking what do I really need these for? I already got a set of 2.3tls but they were local on craigslist so I got them and guess what, I have not seen anything SDA, local in at least 6 months.

    I ran a Parasound HCA 2200 with mine and powered them great IMO. Even more than I ever wanted to go, and the Parsound line up is great. A used Halo series would go nicely with them or the 2200II or 2200 (little less refined) is a good option and I think it was around 500 or so I paid for it.

    Room size IMO is the biggest issue with the SRS as they do need space.

    I'm presently using an Onkyo M508 on my 1.2tl's as a stand in amp while my Mcintosh amp is being recapped. I thought the Onkyo would run out of steam rather quickly being that it's only 1/3 the power of the Mac. But it's actually doing a great job driving the 1.2s and sounds surprisingly good. I'm thinking your 504 will have no trouble powering those SRS's.

    Shipping could meet or exceed the cost of the speakers. I drove over 600 miles round trip in the winter up into Wisconsin to purchase mine from o'le CSTMAR01 last winter. What part of the country do you live in? I just picked up a pair of 1.2's today and only drove about 80 miles round trip...had to pay through the nose but I've got 'em. Now just what I will do with them I don't have a clue.

    The moral here is: figure out how far you are willing to drive and then keep your nose peeled for for sale threads in those areas. You will find some.

    The Onkyo M-508 is the best amp they ever made, the M-504 is not far behind, except lacking in some power.



    My M-504 runs my SDA 1c's perfectly..they sound great and the M-504 doesn't even break a sweat.

    I felt as you, that to run..almost any SRS speakers..the Onkyo may run out of steam. But this maynot be the case.

    The major problem falls in the location..if there not close..the shipping would kill you. So going by what your saying...I will "assume" the Onkyo can do the job, and just look for sets of SRS that are close by and NOT cost a fortune to ship...LOL

    What is your Zip Code?

    You may be in an area near a "quiet" seller and not know it.

    My first trip was 1,380 miles round trip (Atlanta to Pittsburgh)

    My second trip was 3,958 miles round trip (Atlanta to Los Angeles).

    Both trips were well worth it for me. :-)

    The 508 is the 2nd best Onkyo amp with the 510 being the best. With their $5000 original price tag you don't see too many 510's in the wild though.
    No way would I trust anyone to ship SRS's. One year ago this week I left on my journey to pick up mine several states away. It was well worth every minute of that 20 hour trip to make sure they got home safely. I found mine by using the searchtempest function of craigs. I typed in what I was looking for and the miles I was willing to travel and these popped up. 15 minutes after I used it for the very first time I was setting up the deal to pick them up. Good luck to you in your quest.

    I listed one on Ebay,(NOT the one with the cracked casing) but now I'm having second thoughts...I'm afraid I might be making a mistake, but I'm not a collector like you. Reading all this makes me extremely nervous to ship. SO-- maybe I should make shipping unavailable? No one has bid yet, and maybe I should just hang on to them?

    Sorry, your right. the M-510 is the best, But as you say, you never see them so i tend to forget about that amp...LOL



    I'm NOT a "collector" I may have a few speakers but there all well played.

    If your selling your Polks because you don't like them, thats fine. If your worried about shipping, Just state that the SHIPPING is all the responsibility of the person buying the speakers. Or just put them for local pickup only.



    For me, I only have a Mustang GT convert. I could not fit any speakers in that car...LOL So if i found a pair in good shape, they would have to be real close, were i could just borrow my neighbors truck to go pick them up. I would have to sell off my 1c's and RTi's before i could afford to buy SRS's, so not a completely practical idea..(or something that could not be done in a short timeframe).LOL

    Are the M-504s 4-ohm compatible? If so, why would you think you need "more" amp? If the 1Cs are loud enough for you, I'm sure the SRS would be, too.

    The SRS will require a bit more current than the 1Cs, (4 ohm nominal vs. 6 ohm nominal) but if the 504 can handle that...you're set.

    I'm thinking that the later SRS have higher impedance...the amp won't know the difference between them and the 1C.

    No..your right. I kind of get caught up in the bigger is better...LOL Which is why when i see SRS of any model, i go..yeah..I need those. My recollection of the sound of SRS's is from when they first came out, I Know they must be better then the 1C's, how much better they sound when sitting in my listening room, played at the same volume as the 1C's...that i don't know.

    The M-504 has no problems with 4 ohms. In fact the only SRS that runs at that level are the first ones. The next generation and all above them run a 8 ohms.

    Do i really need a bigger amp..probably not. The 504 would not know the difference from pushing the SRS to the 1C's. I do get caught up in the more the better..LOL



    Is the price of a set of SRS any model, with all the shipping and logistic problems, worth the cost? VS just upgrading the 1C's..That i don't know. The 1C's in my listening room are just hard to beat..even unmodified. If i happen to find any model SRS close by, at the right price, then i would buy them. Once i start pulling the 1C's apart, to upgrade..then the SRS is off the table, and ill stick with the 1C's.

    Depending on the size of the room. Small enough room, I can imagine a possibility where the 1C sounds better overall than the SRS. That many drivers need some space to sound "integrated".
