FS: ADCOM GTP-500 Pre-Amp & ADCOM GFA-545 Amplifier

dorokusai

I have some additional gear to set loose upon the world.

ADCOM GTP-500 MkII Pre-Amplifier & Tuner - 9/10 - Black - *SOLD*

This is a neat pre-amp from the folks at Adcom. What's really cool is that I actualy have the original remote control, as they are almost always MIA.

Seriously, the coolest feature of this pre-amp is the ability to swap between Direct Coupled(DC) and Capacitance Coupled(CC) outputs. The DC design removes the capacitors from the output stage for a simpler, cleaner signal path. This was an either/or option on my Cary SLP98F1 and it costs WAY more children. I chose DC for the Cary because it offered better slam and a more open, airy top end. Does it sound better? I think so, but it's your ears not mine. Regardless, you have the ability to decide by just changing the interconnects, I don't.

Here are the features:

AM/FM Tuner w/ 16 Presets
Phono Input
AD Link Capable(Adcom Owners)
Infrared Repeater Capable
3 Audio Inputs/ 2 Outputs
Main Outputs Lab(DC) or Normal(CC)
3 Accessory Outlets
Headphone Output
Tone Controls + Filters

Comments: It's in excellent condition w/ no problems noted.

Adcom GTP-500 Pre-Amp

Includes: Original remote control, original AM/FM antennas, reproduction user manual and HIGH quality service manual ala www.stereomanuals.com

Adcom GFA-545 Amplifier(100x2@8) - 8/10 - Black - *SOLD*

The GFA series turned audio nuts into Adcom fanatics. This is an original GFA-545 and the predecesor to the venerable GFA-5400. Solid, reliable and powerful. These amps have the ability to drive very low impedence loads and are additionally fused and thermal protected. Adcom also uses a proprietary Instantaneous Distortion Alert(IDA) on each channel, to monitor all forms of distortion when they exceed 1%. The manual is a good read for more information on this feature.

Comments: The unit has a small scratch on the center, top faceplate which has been touched up a little bit. I didn't want to overdo it and the rest of the unit is very nice.

ALL my gear is cleaned from top to bottom, inside and out. I check for loose connections and obvious problems. All vital connections are cleaned and treated with CAIG products. The gear is tested in-house on a generic rig to ensure functionality, documented and photographed. I keep the description simple and the photos basic, but additional information is available upon request.

If there is a problem upon receipt of the gear, I am available 24/7 365 via dorokusai@comcast.net.

How does that 545 compare to the Nad 2200 in your opinion? I have the 2200 and it has more power (200 wpc ) vs. the 545's 150. The NAD is high voltage as in the Adcom, but I don't know the Adcom's output.

Assuming you have heard both. What kind of sound difference would you say there is between NAD and Adcom pieces? I also have the NAD 1155 preamp. Essentially trying to figure out if Adcom is better or on equal footing? This of course, is subjective.

Man, I'm seriously tempted to snag 'em both, just to see how good SS sounds with Klipsch. Would be a rockin' backup/secondary system, too.

Univera - I'm actually writing up an ad for a NAD 2200PE now. The 2200(PE) is actually spec'd @ 100wpc/400wpc bridged. The vintage gear is usually rated at MINIMUM power, which I think is cool. It's a very powerful amplifier thanks to the design, very nice amp man. Do you need another? I also love the 11xx series pre-amps.

The NAD is easily warmer than the Adcom, with a smoother transition into the top end. I think the Adcom has it in final top end dynamics, but can sometimes be a little harsh at the limit. The NAD has longer legs when it comes to short term power extension, but the Adcom isn't far behind. Both are stable into 2 ohm loads, dynamic power.

It would be a giant killer rig matched up with the LSi7's from McLoki.

audiobliss

Don't say that! I'm tempted! Though, I'd be much more tempted to get some vintage Polks. For some reason, they've captured my heart, before I've even heard any. I figure a solid 100wpc would do w/e I could find justice.

Thanks for that feedback. Exactly what I was looking for. Warm is good to me. Yea, I might be interested in the 2200.

I have bantered back and forth about getting a couple more 2200's as they are badass amps for the money and I could put more juice on my mains or bi-amp with 4. Or, I could stay with two 2200's and get two 555's for the lowend.

What can you tell me about George D's Anthem amp? Totally clueless about tube gear.

*takes a deep breath*

I'm gonna focus on finishing my main rig, and then maybe do something in my car.

*vows not to check this thread again*

timothyj

I'm interested in the NAD if univera doesn't take it.

dorokusai

Anthem/Sonic Frontiers is another brand I've had alot of success with, especially in pre-amps. I haven't owned that particular one, so I can't speak for the sonics, ask Russman, but I know it to be a very well designed piece of gear. I believe Russ still owns his Amp2....

The SE version adds better capacitors, Kimber Kable wiring....better stock tubes and something else which alludes me. I think that's fairly accurate, although my brain is soft today. The fact it can run a pair of LSi's is impressive.

Ok, lemme get this body written up and posted, that way you guys can get a look at it. Thanks for your interest Timothy.

You should take care of the things that get you to work and school...you have a very nice rig now. Relax, wildcat.

Jockos

dorokusai,

Is that rust on the heatsinks on the GFA-545 or just an artifact of the pictures.

Thanks

faster100

thier aluminum and it don't rust.. they have a bluish color to em if i remember right, i had a 535 and 555 before and looked that way

Faster - Thank you sir

Jockos - He's correct, they are aluminum and it's as you said, just an artifact of the lighting.

Jockos

Thanks

Doro or anyone else, I may have lost my mind, but what are your feelings on bi-amping SDA-SRS's with two of these? There is another available on Ebay with updated power cord. My current plan was using my 7600 receiver (which is a very clean running piece at 0.03 THD) and adding my 2200PE for bi-amped config.

That is way more than I was planning on spending at the moment (for two Anthems), but that might set me straight for quite some time.;) I am blindly approaching this as I have no experience with hybrids or tubes.

1) I would expect a big improvement in sound at this price. 2) I don't want to lose dynamics or kick. 3) Can one use a SS pre-amp for the time being? 4)Do these meet the high voltage demands of the SRS's?

5) You also mention accuracy? Are tubes not as accurate as SS? My listening preferences are towards classic rock, blues, smooth jazz, female vocals. Symphony music is unlikely.

Is that $160 shipped on the 545?
PP... MO ?

Thank you sir.

1) How do I fit into this expenditure? I'm not selling an Anthem, only a NAD amp at a modest price.

2) I can't answer that because I don't know exactly what your plans are for this SRS rig. Hi - Tube, Low - SS....??? If you want bottom end kick, my suggestion is SS, if you want magic top end, Tubes.

3) You can utilize any pre-amp, for any amplifier, at any given time. The results are purely subjective.

4) Do these meet....? I need some clarification here. Are you referring to the Anthem + Adcom?

5) No, I don't think tubes are as accurate as SS and that is exactly how it should be. I would elaborate but that's for another thread.

I know we're in between PM's, so forgive me but I figured I'd answer your questions nonetheless.

GWH,

My FM prices ALWAYS include shipping. I accept all forms of payment but would truly prefer MO, as I take an additional hit on PayPal. Either way, thanks for the response.

This is a sweet, ready made rig for any application.

faster100

$160 shipped, after shipping your talking $120 -130 tops for the amp. even less for the west coasters, what a steal ! :eek:

and yes folks with gas prices, the shipping has increased.. last few larger shipments i have made, have been alot higher cost.. I jump all over inclusive "shipped" items

LOL AB just jump on it...

ok sorry for the derails.

Ok...

160 shipped..

Is absolutely insane...

Ill be back to this thread sometime next week to see if its gone.

What's that amps output into 2ohms? I think I might have found a rig for it. I'm still really tempted...

maxima

Hey Doro,

This 545 would go well in my theater with the other one I bought from George Daniel. I would like to take it off your hands if still available. I will Papal from my bank or send a check. Either way should be free of fees to you. Thanks,

Eric

I don't think Adcom rated this amp for 2omhs

what would yo have that is 2ohms?

just wondering

audiobliss

Well, phooey. I was just fixing to say I'd take the both of them. More so for experimentation than because I need them in a rig. I've realized that the only way to learn in this hobby is to hear everything you can, which neccessitates a lot of gear swapping.

If maxima backs out, I'll take them. If not, then I've still got some warm tubes!

Hahaha. That was a brain ****. I meant 4ohms.

Man, I have a hard enough time typing, but this new wireless keyboard is killing me.

Maxima - I think that Jockos is solid on the amplifier at the moment and we're discussing the pre-amp. I will let you know if anything changes but I appreciate your interest either way.

AB - Go clean your room!

Faster/ Zero - Thanks for the comments.

Hoosier - You need a better skill set.
