    That's supposed to be a very solid CDP, and match very well with the 750/5802.

    I really like the fact that you can use it as a DAC for another digital source. Very cool feature. HDCD decoding is a big plus too. It's only drawback is lack of SACD playback.

    I wonder how the $500 750 cdp compares to others in its class. I thinking about this cdp as well but wonder how the Jolida 100 or the Rotel 1072 would sound with my Adcom setup. You don't hear to much about the GCD-750.

    I'm sure it would probably excel beyond the Jolida and Rotel. Remember the 750 cdp was a $1500 player and has the same digital and analog section as the GDA700 dac and that is a superb sounding dac.

    When I finally added the GFP-750 preamp to my system it was a very "educational" experience. For the record, some of the previous pre-amps I have used include... a Yamaha (who's model I don't remember), Carver CT-Seven, Adcom GFP-555, Adcom GTP-500II, and a PS Audio 5.6. The PS Audio is definitely the best of that bunch (and is still used in my home office system), but the GFP-750 simply blew it away. The word that best describes it is "transparent". Compared to the GFP-750 all of the others obviously "colored" the sound. The GFP-750 simply disappeared.

    The GFP-750 can be used actively or as a passive pre-amp (as can the PS Audio 5.6). I preferred the active mode as it better supported the dynamics of the music, solidifying the impact of transients without changing the tonal balance or coloring the sound.

    I guess this should be no big surprise. Stereophile found the GFP-750 to be an outstanding preamp, giving it a Class A recommendation. And on the used equipment market it still can command as much as $900 ($750-800 being more typical). I can only agree with all of the positive things that have already been said about this preamp.

    Agreed! I plan to eventually feed that input with a Wadia 170 iTransport.

    You don't hear to much about the GCD-750.

    I had the GFP-750/GFA-5802/GCD-750 combination in my two channel rig for a few years and also had a second GFP-750 in another system. I sold the pre and power amps when I upgraded but kept the GCD-750 as a backup CD player and to use when breaking in cables.

    The GCD-750 is a great player, but it's dim, cheap looking amber colored LED display discouraged many from buying it. Adcom said they chose that particular display, which is unreadable from a few feet away, because it was a very low noise design. Vacuum florescent displays do introduce noise, but a lot of CD players that use them have an option for dimming and/or turning off the display. I sent an email to Adcom asking why they didn't just use a dimmable/switchable display, but they never answered.:confused:

    I like my GCD-750, but I am not as enthusiastic about it as I am the GFP-750 and GFA-5802. Perhaps this is because I have a PS Audio Ultralink Two to compare it to. The Ultralink Two was a Stereophile Class B component as recently as 1998 (IIRC) and retailed for around $2200, so it is certainly an able competitor. The GCD-750 is definitely preferred for HDCD encoded material, but for straight redbook playback, it is a close call. The PS Audio is a bit warmer sounding, while the Adcom may possess a bit more detailed top-end... but I won't commit to that. I do prefer the GCD-750 when it is connected via its balanced outputs instead of unbalanced, but I have not compared it to the Ultralink Two when both are connected via XLR. I also have a Marantz DV7001 DVD/SACD player, and the GCD-750 definitely outperforms it for CD playback. I guess the very fact that the GCD-750 isn't blown away by the Ultralink Two is testament enough that it is a very solid player. I am just not ready to heap the same praise on it that I have for the other two Adcom pieces from this series.

    Cool! I think I've seem them in the AudioKarma too. They looks superb!


    Larry (OP), the GFA-5802/GFP-750/GCD-750 is an awesome combo. ;)

    Well I have the GFA-5802 hooked up, and it sounds Fantastic!!

    The only thing i notice is I do get a little bit more buzzing sound from my speakers then I did from the 585. it don't really get any louder when I turn the volume up, is this normal from this amp?

    It don't seem to be affecting the sound quality when a CD is playing.

    On another note I like that my music sounds a little warmer, and the clarity and dynamics is cleaner with the bass being much tighter. also I noticed the imagery with the SDA's is more pronounced from side to side as well as across the room.

    I will be able to play with this setup for a few days till I get the GFP-750 this week.

    I am very glad the XPA-2 did not work out for me as this amp out the gate blows the XPA-2 out of the water period.

    Now can someone help me with the slight buzzing sound?

    Thanks,

    Larry.

    Wait until you get the 750 pre. Perhaps your AVR as a pre is causing some issue.

    Ah, missed that. Going to have to hunt it down. Might be a ground loop thing. Try different outlets. Make sure no cable boxes are plugged into the pre. I have a very very minor ground hum as well which gets worse when I have the analog outs of my cable box plugged into my pre. A power conditioner/filter has helped but I can still hear an ever so slight hum if it's quiet and put my ear to the speaker.

    This is a two channel setup only, Music only. I have it plugged into the same outlet I had the 585 plugged into. I can hear the sound 12 to 15 inches away.

    I have my eye on a power conditioner, I want a Panamax or APC.

    Thanks H9,

    just for grins you might try one of those 3 to 2 prong adapters, I have had buzzing coming from the third prong on one of my subs.
