"Un" bi-amped my fronts

Schwingding

Have been running my fronts (RTi10s) via the assignable amp feature on the Yamaha 5990, so it was using the surround back and the main amp to power the fronts. It sounded better instantly, a great deal better in fact, probably due to the fact that the RTi10s are a bit power hungry for that receiver.

But I blew a tweeter recently, and I figured I was driving that receiver hard and probably getting some clipping.

So today I took posession of an Adcom GFA 545II (100wx2) amp.

Connected the preamp outs for the front to the amp, and the amp to the speakers. Reran the YPAO auto-config, and gave it a test.

YIPPEE! Clean, powerful, and sweet! Sounds better than the bi-amped setup previously, without a doubt, and that sounded nice. Much more "presence" to the speakers, very impressive!

And now I have the surround back amp back for them.

I fear this was a bad step for me, financially...

congrats.. did you replace the bad tweeter?

ronnie

that adcom is actually putting out more clean power than your reciever is...you made the right move.

The whole speaker! One of the few advantages of buying locally from Tweeter at a higher price - just returned to the store and they swapped me for a brand new unit.

intergrateds (if that is what you have) cannot compete with a dedicated amp. My denon could never hope to compete with my outlaw 7500. never.

He was using his AVR, he then added a separate power amp to drive the fronts. Integrated amps are for two channel music and I guarantee you that there are integrated amps that will smoke a helluva lot of separates.

amps, amps amps...every one has an amp or more....but me:mad:
That's it I'm on a mission to find an amp !
Oh BTW glad you are enjoying your new upgrade

of course that's true, but my denon was not one of them. Asking it to drive LSi's (fronts, surround, center) at 4 ohms was never a nice sound. The ratings in the manual for my Denon AVR-2105 amp don't even show 4 ohm ratings, they stop at 6. And at 6 ohms it has a very high THD%. Of course lightening the load of an intergrated will help out. With that set-up (not my sig set-up) I had the fronts set to large and no sub. I used Polk's solution which is line-leve using an unfiltered signal (I don't do that anymore). Asking the fronts to dig way down as well as having a center that can work low taxes (or taxed) the AVR 2105 I had. Will that happen to Denon's top of the line flagship models? Not likely. That's why they cost so much.

The Denon AVR 2105 will stay in the family. It powers the family/kids home theater. I does quite nicely powering the RTi100 fronts and the CSi9 center. And it was a very obvious sonic improvement from the JVC it replaced. That JVC . . .man. I can remember years ago when that amp cost like $700!!! It is the model RX-888V. When I replaced it, I pondered using my sledgehammer to pound it to see how good my sledgehammer was.

WTF are you talking about? INTEGRATED amps have nothing to do with HT.

I thought that technically an "integrated amp" was just a receiver without a tuner built in.

Wikipedia agrees with me....

An "integrated" is anything with a pre- and power in one box. However, the convention around here is to refer to HT receivers (like denon, yamaha, onk, etc) as an "AVR" or "receiver" and stereo pre/power in one gear (like krell, MF, jolida, plinus) as integrateds. F1nut knew exactly what you meant, he just likes being an ****.

And yes, my krell kav-300i integrated will smoke many amps- the Adcom 545 among them.

yes my bad. I was confusing my old Technics integrated with the whole a/v concept. my bad. But #1, what I said about my denon holds and #2 I don't really think that my confusion rises to the level of a "WTF." Seriously. We are all adults. If I want "WTF's" I can go to any gaming forum where pimply teens talk about how bad aze their level 14 dark elf is. Come on.

Some integrateds actually use two boxes, one just for the power supply. Correction, I knew what I was talking about, made that point once, didn't seem to take, made it twice, seems to have worked. If you think that makes me an ****, then you have a lot to learn.


WTF is a commonly used term around here, no offense was meant by it. Part of being an adult is developing a thicker skin.

There's a lot more to it than that.
