Please help me find the right power amp for my setup.. Adcom GFA-545 II?

Okay thanks. I see. I'll run the lsi7 only until I can get my new receiver straightened out. Mod can close this thread if you want. I think I'm all set.

I found a new HK-3490 for $280 on buy.com.
This is the latest ver. and has a sub out and the preouts and main in. seems good for the price. I was going to get the Outlaw Audio RR2150 but more money than I can afford right now. I think I'll be able to run everything how I want to on the HK.

I live in NY. J&R Charges me sales tax. it was cheaper for me to buy from electronics expo/buy.com plus the whole point was to buy from buy.com so I could use my Revolution card..

Thanks Lee! The Shipment arrived safe and sound. I ordered some nice cables for cheap from monoprice.com yesterday. I am going to set it all up tonight when I get home from work! Next stop .... Hi-Fi heaven! Thanks for the help everyone.

I'll have the landlord banging on my door in no time with all this power!

What about this possibility? Get the Pre and Amp deal from Leroy, run a source (CD, Tuner, iPod) into the preamp. Y-Split the Preamp outs -one set into the existing Onkyo's line inputs for driving the Rti's and sub, and the other set into the 545II for the LSi's.
Maybe??

Mmaden you're a frickn genius!

I'll get to that in a minute. I bought a HK-3490 replacement for the legendary 3480. It has preout and main in plus a sub out. I thought man I'm all set this is exactly what I need. So today . lee's Adcom kit arrives plus the HK unit. So i'm thinking all day at work about this. Finally I get home and unpack everything. The HK unit is beautiful. The pre and poweramp from lee look like they've never been used. All original packaging and he included very high quality rca cables for the power amp. I take the Onk out and start connecting cables. the plan is use the preout for the amp to drive the lsi 7. then use the speaker 1 terminal for the Rtia1 set and the sub out rca for the psw111. I get the amp hooked up and run the lsi7 off the pre and sound is amazing. then I hook up the rtia1 of speaker 1 terminal on the HK. and no sound. sub out works fine. so what happens is when using the preout on the HK it bypasses the integrated amp in the HK.

Next I run the power amp off the HK tape 2 out. it works like onkyo told me but no way to adjust the voluime for the lsi7. so this is a definite no go.

I was like shoot I paid extra for this and not working to my favor.

next I'm thinking run 2 receivers separately

1 for pc and the other for the tv, record player dvd etc.

run the rtia1 off the onk on my computer desk and run the lsi7 off the adcom pre and return the HK to buy.com.

then I noticed a set of 4 rca outs on the Adcom preamp. I run the 2 main outs into the adcom power amp and run the other 2 outs in the cd line in on the back of the onk. I run the psw111 of terminal b and the rtia1 off terminal A of onkyo. And LSI7 off the poweramp which is running out of the adcom preamp out.

It works perfectly! There is no hum or high pitched noise like h9 warned about. The power amp and the pre's feel warm to the the touch but not hot at all. I can turn it up as loud as it goes and the nothing shuts off!!

it sounds frickin amazing and I hear no difference in sound from the lsi7 than I did when I initially started. All I do is adjust the volume levels on the ONK for the sub and rtiA1 and then turn up the Adcom preamp which adjusts all 5 speakers simultaneously. Then I play with the pc speaker setup. it sends a chime to the left and right speakers so you can identify left from right channel. the problem is its rings both rtia1 at the same time for the right then rings the lsi7 for the left. ????


I checked my connections and instead of using terminal A left and right for the rtia1. I run the right RTIa1 off terminal A Right and the left rtia1 off terminal B right. (two rights???) but now it works. left chime right chime. lsi7 included.

SO my conclusion is. IT all worked out. mmadden was right all along. lee gave me a sweet deal and I got to use the preamp wisely. The HK is going back to buy.com and I get to keep the onk in the mix. Eventually I will sell the Rtia1 and get another set of Lsi9s for my main and use the lsi7 for the computer.

Thanks to everyone for the help. I hope this thread helps others in the same ship. I think Polk forum is amazing. I am an avid computer overclocker and am on xtremesystems.org. I cool Intel quad and dual core cpus using dry ice and liquid nitrogen. XS is the best overclocking forum in the world. I would like to say polk forums is the xtremesystems forum for the Audio Enthusiasts.
this is a huge compliment fyi.
Take care.

One other thing I like about this setup is I can adjust everything independently so I can turn down the lesser RtiA1's and run the Lsi7 higher so they are the dominant speakers in the setup. I wish you guys could hear my rig. I think you'd all be pretty amazed. I'm freaking out over here. I am speechless.

Nope,$300 can buy you lots of new tunes.

Glad to hear this from another music lover. I am going to get Brand X Moroccan Roll and Unorthodox Behaviour on Vinyl. These are quintessential Acid Jazz/Fusion Albums. Phil Collins' first band he was in and plays drums like Neil Peart on five hits of acid! If you guys don't Know about Brand X and enjoy heavy drumming and rock/ jazz (don caballero). Listen to these 2 albums from the band that started it all. You'll be amazed.
