Wanted! 2-channel Amplifier!

Recommended Posts

Have you checked e-bay?

We had a thread going last week about that amp, there was a buy it now pretty cheap.

The 555 is an e-bay regular.

The 555 is a geat amp. Make sure you do some googling and get to the various links that talk about the mods and updates for this amp. Some of these mods are fairly simple if you know your way around a soldering gun (i.e. mylar by pass caps on the power caps) and are reported as improving the amps performance.

The Oknyo M-50X line is an Ebay regular as well.

Memory tells me there is (or was) a dbx BX-1 available in Vermont.

It's configurable from a 2-ch to a 3-ch or 4-ch amp. It has a smaller brother (BX-3) that you'll see on ebay every now & then (fairly inexpensive too)

I've got one of each and am impressed with them. The BX-1 however, hasn't been put into my system too much, I just got it several weeks ago.

Yep, there is a killer DBX BX-1 available at a fabulous price. I think he was looking to get $600 plus shipping (it is a full 2ft long and weighs 100lbs - no joke) Look at the Adcom GFA-555 thread that was active last week there are photos and a copy of the user manual posted.

The DBX BX-1 will put a whompin' on the Adcom GFA-555 and many other 2 channel amps. It retailed for $5K after all and had a street price of about $3850. It is a monster and is built literally like a tank but it sounds stellar. They are also very rare with only about 2000 built worldwide.

It is a 2, 3, or 4 channel configurable amp 400W x 2, 125W X 4, or 125W X 2 & 400W

Contact TravisC (Wayne) on the forum.

Here is the thread look on page 2 for the user manual it is a great read.

It was too big for Mike Lindsey's audio rack so he declined. It is still available.

Wayne has the complete printed schematics and rework procedure for it as well, I know I gave them to him I was running two BX-1's in 4 channel mode for my HT and it was incredible. I also have digitized copies of them.

I downsized last year to the Sherbourn 7/2100A which is also an incredible amplifier and is a true 7-channel mono block amp.

I compared a pair of McIntosh MC-30's to the BX-1 in 4 channel mode and the differences were negligible to my ears on my Klipschorn mains. Sweet amp.

You able to email me a copy of those? I'll pay for the stamp [;)]

Richard, didn't Wayne send all those to you when you were considering his amp because you wanted to show them to Terry DeWick? I thought you had them all already. If not let me know and I will send you what I have.

The Schematic scans are quite large and would need to be printed on an a large format printer as the big one is a size "E" drawing 34" x 44" the others are smaller "C" and "B" size engineering drawings and the rework procedure is the standard 8.5" x 11" they can all however be viewed on a viewer since I scanned them at a high resolution on a wide format scanner that I have access to.

What I recall he sent me was perhaps a picture of the schematics rather than the schematics themselves.

So, if you've got them in electronic form & can send them, it'd be appreciated. I hope I'd never need them (especially since Terry isn't too keen on delving inside there), but ya never know.

I sent you a PM with situation/question about them, so we don't further steal this thread.

I have a Yamaha MX1 you can have for 350$ plus shipping. It will more than push anything you have and is stable to one ohm. Shipping would be high i think because it is like 60lbs. But let me know it works great im just not using it anymore just sitting in my rack.

I'll put this up for you and anyone else who might be interested here on the klipsch forum that is reading this, I have three Kenwood KM-208's for sale, all have been gone through and updated/fixed as necessary, I wouldn't sell anything that is less than perfect. 150 watts x2, capable of driving 4 speakers, split a channel with a y adapter and bi-wire your speakers and you would have an effectiv 300watt monoblock. I've been using them with good results to drive RF-7's. I put them up on ebay just cause they had a special .20cent listing day and thought I'd put them up for the heck of it. Even though I put some money into these with the updates, I'm buying an emotiva. Price is 150.00 each plus shipping, but for a forum member wanting to purchase all three I'll make a special price, contact me at rushisrighton@yahoo.com if interested.[;)]

This thread seems like a good place to ask my question. I have

four Klipsch AW-650's still in the box that I just don't have anything

to power them. So, I need a recommendation on a two channel amp

that won't break the bank.

I am running a 7.1 reciever inside, and think that since my outside

speakers only have to do music, I could run cables from my CD player

(Pioneer PDF-1009) which has both coax and optical outputs to two

different recievers, one to my Yamaha inside and the other to a second

high amp reciever. Then I could connect the outdoor speakers to a

second 2-channel amp.

I am thinking I need to run

one pair of outdoor speakers to the "A" and one pair to the "B"

switche. The advantages, if I am correct, are(1) I could choose

to play one pair

or both outside; (2) no need for a speaker selector on the outside

speakers; (3) a

second amp provides volume control for the outside independent of the

inside (4) this setup would free up my A/B/A+B switch on the

main/inside amp so

that I could put speakers in the garage, master bedroom, my daughter's

room, etc. via a speaker selector switch (considering the need of

running more than one pair at any time on this amp (B switch mode)

would be rare.

First, am I correct on my application analysis? (IE: Will it work?)

Second: Suggestions? I have a tight budget so I have to

find used and even then, I am not going to be able to go high end.

I have a new question. I have read post that say separate

components are better than a single integrated receiver/amp. So,

which of the separate components has the volume controls on it? I

am still trying to power those four AW-650's I bought. I secured

a 2 channel amp with enough power, but no volume controls. I can

come out of my Yamaha's zone 2 pre-out but I need volume controls,

alternatively, I can use the analog output on my CD and bypass the HTR

altogether. So, what component am I looking for now. Any

help would be appreciated.

This question is often asked by the newer people to this hobby.

The Pre-amp (pre) or Pre-amp / Processor (Pre/Pro) is the component that

accepts the input from your turn table, CD player, DVD player etc. It is the

unit that has any tone controls and it has the volume knob.

The Amp or Power amp, may or may not have input adjustments (for matching the

power amp to the pre-amp) most do not.

An integrated amp has both the Pre-amp and the Power amp in one box.

A receiver is an integrated amp that has a built in tuner.

If your receiver or integrated amp has PRE-OUTS, you can bypass the amp

built in the unit and send the signal to the stand alone Power amp. The Pre/Pro

still controls the volume of the combo.

EDIT: The power supplies on most HT receivers is on the low end of "just

enough" so many people will use one or more stand alone amps to power the

speakers in addition to the receiver they have. This is what I am doing with my

HT setup. I have a Yamaha RX-V 750 and it is doing a bang up job but I tend to

listen at louder levels in the HT so I am adding a stand alone amp to take the

duties of either the main speakers or the rears from the receiver. This will

lighten the load on the receivers power supply and thus help it to run cooler

and there by helping to extend the life of the unit and getting cleaner sound

in the process.

rlr, just what do you want to do? Are you setting up a separate

2 ch system? Indeed, if the CD player has an output gain control you can run it

straight into a power amp and bypass the preamp completely but if you want to

listen to other things on the power amp, you need to switch between the sources

thus you are looking for a preamp. I dont know which Yamaha unit you have but

it can probably function as your preamp. More info will be needed to help you

with your question further.

Sorry, I just saw this post.



1), yes if you ran a second integrated amp or receiver to
only power the outside speakers, you then would be able to control the outside
speakers independent of the inside speakers and yes the source CD does not care
which unit it will send signal to. If it will send signal to both outputs at
the same time, you will get a signal at both preamps. (Receivers)



2) If the second amplifier has outputs for two pair of
speakers, you can run one or the other or both, switched at the second amp.



3) If you used a speaker selector switch, you can then
choose which speakers to run wherever you wish.



Another way to do this is to use the pre-outs on the main
unit to feed one or more separate power amps that in turn power the speakers at
the remote locations. You then can control the volume at each location with
volume controls at each location that provide a constant load to the power
amps. Such as this. In this way, you adjust the main preamp to get the
loudest volume you want and then adjust each location down from there.
Everything would then be controlled by one pre/pro.
