Next upgrade to the biamp mini-rack system ...

The L & R front channels come off the HK AVR 7300 at preamp level, go through a Yamaha 1/3 octave EQ which lets me bump the bottom up just a bit for movies and TV (Its usually in bypass for music).
Next is an Ashley XR1001 active crossover set at 290hz to feed the low split to a dedicated amp and the high split goes to another amp that feeds the passive in the speakers and their 3 drivers.

I've been using 2 JBL/UREI amps in the system for over 2 years, both of them are in super clean condition. The higher powered 6260 runs the two 2235 woofers, and a slightly lower power 6230 feeds the high side.

Today I put an old Adcom GFA-555 into place to run the low split. I'll let it play for a while just to be sure its stable, I think its a winning change.
Emma says its the best those speakers have sounded in a long time.

One thing I'm thinking of is to get a second GFA-555 and do what Rolf had recommended a while back. Use one amp for the left speaker, and one amp for the right speaker.

I did put a pair of the White Lightning Moonshine cables in place on the left speaker. I've got to make the second pair up and put them in place to the right speaker - but that change seemed transparent - certainly better than HomeDepot RCA Zipcord ...

Another upgrade - found another Adcom GFA-555 this week on Craig's List - drove out Tues evening to grab it before it slipped away!. Its the slightly newer version of the original GFA-555 series - its not the II version.
Anyway, this afternoon I shuffled the rack so I had room for it, its taller than the 6230 it replaced!
I currently have the rack set with the finned amp running the hi-split and the lower run on the woofers, but at this point I can swing wires around and use one for the left monitor, one for the right monitor as Rolf recommended a while back ...

Maybe next week ...

The amps are nice thou I would have kept that JBL Urei amp. How does it, how do you think they fair with Casino Royale that is what you’re testing them with? Have look at the frequency response http://www.audioheritage.org/vbulletin/showthread.php?p=275346#post275346

Its real pucker Dolby mix this one is.

BOTH of my JBL/UREI amps are for sale - got better ones now.

Bond movies - we're both Daniel Craig fans (Bond, Our Friends in the North, The Golden Compass, Lara Croft: Tomb Raider, Layer Cake, Munich, Defiance, etc)
Emma saw the Free Running sequence at the beginning of Casino Royal on SciFi Channel,
so I looked them up on Amazon and found I could buy Casino Royal 2 Disc ver for under $5,
and I got Quantum of Solace for about the same ...
we'll watch them some time when its slow - prolly few months off -
but all that graphics and sound chart hooey?- thats OFF TOPIC in this thread, thanks ...

Hey, where do you get those 19" rack mount vents!!!!,?

Hey, where do you get those 19" rack mount vents!!!!,?

Parts Express - tho the feet on the ADCOM amps are so close to the front I had to flip the bottom vents backward to clear them!

# 262-100- Penn-Elcom R1286/1UVK Perforated Rack Panel 1U

Think they were about $10 each

Its the slightly newer version of the original GFA-555 series - its not the II version..

thats the ver that I gots too (but no rack mount)...did a little reading, the GFA-500 series is the one that they brought Nelson Pass in for consultation...when he left, they mucked around a bit and added to his design for the GFA-555II version...the forums like the first one better (both have same power ratings)

"The Adcom GFA-555 was a powerhouse. Output at clipping was 231.7W into 8 ohms (23.6dBW), increasing to 331.9W into 4 ohms "

got mine cheap..one of those "free to good home" ads...PO called FSOM and they wanted $100 to look and estimated $300 repair -over the phone- . I did a little netreading and found the internal fuse blowing to be common, so opened it up and replaced 2 of them ...works fine now, tho keeping spare fuses handy....next time wont put back in all 18 screws in the top.

here's mine

Had a hum in this system for quite a while - finally got rid of it 6 weeks or so back by using a ground cheater plug on the ACE-515 when its plugged into the wall.

The earlier this week Emma heard a hum - on the left side. tracked it down to inside one of the GFA-555 Amps - my guess is its a transformer hum! Not sure what to do about that - but it's pretty quiet and not audible if you have any sound playing - you only hear it when the system is muted or between tracks on an album.

Been a while since I touched this thread ... Got the HK AVR 7300 back from repairs at Northridge - so far it seems to be working great!
I still thinks its a superior unit, when it works (it was a bit ... fragile).

Got an OPPO BDP-93 for Christmas - its been quite nice - great sound on HDCDs, SACDs and the like, BluRay plays very well, even standard DVDs playback very nicely ...

Today we got a 47 inch Vizio HDTV to replace the aging Philips CRT HDTV ... and as soon as I connect the HDMO cable to the Vizio - I got a nasty hum throughout the system!
There is no other connection between them - its same HDMI cable I used with the Philips

ARGHHHHH

[hjames]

Fixed the hum - for now ... lifted the ground leg of the TVs 3 prong plug and all is silence ...

Maybe I can rewire the outlets once that 220lb Philips CRT HDTV is off the cabinet and out of the room, but for now, I can enjoy the sound and good pictures!

Pix to follow later ...

its been really interesting watching you tweak and build your system over the last few years .
You have worked hard and deserve to have great fun with it .
