Welcome, good to have you onboard. You will meet a group of tech savvy gentlemen here, generous of knowledge, DIY guidance and gear. My skill level tops out at screwdriver and soldering iron but reading everything here enabled me to rescue my old ALS, make informed choices on improving home audio and for that I am grateful. Best wishes on your project

Nice gear Kmh! Vinyl aficionados here will asking about that turntable and what spins on it. How did you come by your setup?

Buddy Rich and Gene Krupa in movies and on black & white television shows were the first drummers I was aware of and too young to appreciate. My list of favorites is a subset of this thread's list, to which Billy Cobham I will add. He is the one to shock me out of a teenage In-A-Gadda-Da-Vida mindset.

Howdy, Chris! Carver is in your ancestral tree, so to speak. We all have diverged from a common ancestor, The Bobfather. Lots of helpful members with extensive knowledge; a great community to learn within.

Hello, Jim. As for preamps, you will find the Carver C1 Sonic Holography preamp is the perennial favorite here, with modifications available. Look for them on eBay or CraigsList. I have a C-3 preamp and a CT-7 pre/tuner (no C-1) that are just fine. Many friends here who will help you on your quests.

Benvenuto, Antonio. You are in excellent company here. Please tell us how you came upon your Carver gear:: How did you learn about Carver audio equipment? Where can it be found in Italy? Do you have a ":dream" setup? There plenty of helpful members on this side of the Atlantic to help you realize your dreams.

I, too, chanced upon The Forum, hoping to save some of my gear from the rubbish heap. Listen & read is my middle name as I am not talented in the audio gear world, but with knowledgeable forum friends kind answers did come, and still do. Happy to have you onboard!

Duplicate.

Pics of Amazings always make my heart flutter and not to mention the remainder of the system. Thanks for the pics & welcome!

This is an enjoyable topic & there seem to be some common denominators. My selections have changed over the years, these would on the list nowadays: Pat Metheny, The Orchestrion Project: his orchestrionics, madhatter automatons, layer rhythms and counter-rhythmic motifs over guitar. (Details, spatialness) Cameron Carpenter, Revolutionary: the piece, Solitude by Duke Ellington, arranged for his revolutionary digital organ, with its many Wurlitzer voices, spans the dynamic range from whisper to crescendo, including a climactic cymbal crash! (Dynamic range, tones) Chris Botti, Italia: tracks featuring Andrea Bocelli and Paula Cole in lush orchestral settings (male & female vocals) Henryk Gorecki, Symphony #3, featuring Dawn Upshaw: his relative harmonic & rhythmical simplicity in this slow, contemplative work lays bare the beauty of soprano voice and strings (clarity, dynamics, female voice) Sting, Symphonica: Sting's sustained high note that fades to close When We Dance is delicate, and I Burn For You is floated with subtle percussive & orchestral polyrhytms (detail, male voice, spatialness) King Crimson, The Power To Believe: the Crimson's unmistakable sonic crunch on display (impact, power handling) Patricia Barber, Companion: a live recording, the woody resonance of upright bass introducing Use Me (low end dynamics, female vocals, soundstage) Patrick O'Hearn, Eldorado: instruments & percussion span the entire room, like fireflies flitting on & off at nightfall (soundtsage) Time to check the other entries!

Thank you, Dennis. This will help

Listening to the CD and reading instructions that are legible. There is info in the booklet complementary to but not in the audio tracks: Track 1 Inroduction: Introduces the C-4000 & congratulates you on "the ultimate listening experience" afforded by SH. The recorded tracks will help set up the system with SH but will benefit users of ordinary playback equipment. Be sure to set your system controls to stereo operation! Track 2 Loudspeaker Phasing Instructions: How to determine by listening to the track; how to correct. Even if you do not understand speaker phasing, one can just listen and know whether or not a problem needs attention. Track 3 Absolute Phase: Ditto above. Track 4 & 5 Frequency Response: tones to check speaker frequency response (and the listener's hearing!): 1 kHz, 15 kHz, 10 kHz tones–the 15kHz tone is very hard for me to hear unless close to & on axis to the speaker; ambient household & environmental noises compete. Yikes! Then: 5kHz, 100 Hz, 50 Hz. Then: 1000Hz, 24 Hz, 16 Hz. Check your subs, your hearing & room vibrations! Track 6 Log Sweep: sci-fi spacecraft taking-off sound effect with low-to-high frequency sweep. Cats think it is creepy. Track 7 Electrical Balance: switch Stereo/Mono switch on & off; the sound volume should diminish in mono mode. Track 8 Autocorrelator Adjustment: I hear nothing on this (using CT-7). Track 9 Peak Unlimiter Adjustment: ditto above. Love the name. Track 10 Time Delay & Echo Density: nothing for the CT-7 to attend to. Track 11 Introduction to Tracks 12, 13 & 14: Designed to be used with SH; noise bursts on the left channel, then the right; these noise bursts are guides for adjusting speaker toe-in, speaker placement and optimum listening position (left-right, front-back). Properly set-up, the sound appears to be coming from over there (point 45 degrees out to the side), not from the speaker. Leaning the head towards the side of the speaker (leaning right with the tone only from the right speaker) shifts the image left towards the middle, between the speakers; leaning left shifts the sound, in this case, towards the right speaker. Back in optimum position, the sound is way off to side, out there somewhere, definitely not from the speaker. This could be a party trick! Track 13 Music Track 14 Holographically encoded music: if you do not have SH. Track 15 Pink Noise: Yes, but don’t know how to use this. Cannot read the instructions.

The printed instructions to my SH Holography Demonstration-Calibration Test Disc (CD) are tenaciously stuck together. The top halves of pages have yielded to patient separating but the bottom halves are losing print. I do not see the instructions in the Database. If it is available, please point me in the right direction. Much obliged, friends.

I am # 1 Godzilla fan; reruns of the classics, especially with Raymond Burr, captivate me. Will be looking for this at an iMax theatre-big, BIG, BIG! .

Hello, Bob. Thanks for the pictures sans cats. I've got them–so does my ALSs. Polk SDAs… Your fluffy white companion looks great company for music from a great system. By the way, your are entering here the OCCD Reality Distortion Field. Might as well surrender.

All of the early Pat Metheny'Group recordings on ECM are on my remaster wish list. Nonesuch is issuing remasters of the later work. Mahavishnu Orchestra recordings could use a redo, the sound is a compressed muddy mess.

Capt. Beefheart' wrecked my teenage mind: Old Fart At Play Pappy with the Khaki sweatband Bowed goat potbellied barnyard that only he noticed The old fart was smart The old gold cloth madonna Dancin' t' the fiddle 'n saw He ran down behind the knoll 'n slipped on his wooden fishhead The mouth worked 'n snapped all the bees Back t' the bungalow Momma was flatten'n lard With her red enamel rollin' pin When the fishhead broke the window Rubber eye erect 'n precisely detailed Airholes from which breath should come Is now closely fit With the chatter of the old fart inside An assortment of observations took place Momma licked 'er lips like uh cat Pecked the ground like uh rooster Pivoted like uh duck Her stockings down caught dust 'n doughballs She cracked 'er mouth glaze caught one eyelash Rubbed 'er hands on 'er gorgeous gingham Her hand grasped sticky metal intricate latchwork Open t' the room uh smell cold mixed with bologna Rubber bands crumpled wax paper bonnets Fat goose legs 'n special jellies Ignited by the warmth of the room The old fart smelled this thru his important breather holes Cleverly he dialed from within from the outside we observed That the nose of the wooden mask Where the holes had just been uh moment ago Was now smooth amazingly blended camouflaged in With the very intricate rainbow trout replica The old fart inside was now breathin' freely From his perfume bottle atomizer air bulb invention His excited eyes from within the dark interior glazed; watered in appreciation of his thoughtful preparation.

Bowers & Wilkins offers Society of Sound, a music subscription curated by Peter Gabriel & Real World Studios and the London Symphony Orchestra. Trial members can try out the music for free & download selected tracks. Members receive two hand-picked studio-quality album downloads each month plus a selection of catalogue albums; all available in Apple Lossless or FLAC 24-bit. I am doing the trial; the catalogue offers artists & music I would not normally consider or even know of and so far have been pleasantly surprised. The FAQs were helpful for me now just getting into digital downloads, a new dimension in my music library.

In, thank you very much.

From what I am learning in the forum, tightening too much the screws may damage the ribbon assembly and too little allows buzzing. How does the original factory assembly avoid this? I would be in interested in learning how the factory assembles the ribbon components. My imagination runs off to some miniature torque wrench that should be in my tool kit. Perhaps someone in-the-know here would like to share insight into this matter. Back to listening again today and minimal (1/8-ish) turns. So far each screw1/8 turn has met no resistance of the kind sensed when a screw has reached or is very near the stop point. Pat Metheny recordings, his electric guitar tone, reliably buzzes, so it will be Pat & me today.

Thank you, makes sense, but being cautious comes with inexperience on my part. How far has any one particular screw been turned been by anyone doing this procedure? I've done 1/8 so far and not resolved the buzz sites. 1/4? 1/2? Proceeding with caution (jeez, you'd think I was doing touch-and-go brain surgery). Thank you for ongoing support.

Regarding tightening slightly the screws at the level of buzz, may this be performed whilst music is playing or is it to be done with no audio signal. I have identified at least two, maybe three, buzz zones.

You fellows are sharp. Back to the second hand store for another wine rack.

I will apply delicate attention to the screws this weekend, thank you for the emphasis on minute turns. As things stand now the components hide out of sight behind the left speaker, the True Sub Jr. behind the right speaker.

Thank you for the warm welcome, that is very nice. I will review the posts regarding ribbon buzz & selecting appropriate screws to minimally tighten, as well as humidity, although I think it is a low humidity situation indoors this winter–but humid summers in Northern Virginia. We tend to keep the windows open spring through autumn. What would be the benefit, if any, to running a hair dryer set to low heat & low speed from a distance, not close, over the buzzing area? Bad idea? Not trying to shrink wrap the ribbons like the window insulation treatments I put up in winter. Future plans: perhaps introduce the second M1.0T into the system, both set mono, driving their own speaker. I have yet to top-out the M 1.0T LED lights, so would there be any real sonic benefit? My guess is probably not. These, as I have learned here, are the non-inverting models so a flip of the switch on the back panel would precede a new hook-up. Still experimenting with the Sunfire True Subwoofer Jr. crossover level & volume. The ALS's bass is incredible, more so than in the past and I attribute that to room placement, having back and side walls walls not opening into another room or hallway. I have set the crossover at 35 Hz and the volume rather low and the low end is very nice. My wife said it is good to have Big Music (her words) again, meaning the sound & soundstage of the ALSs. I will post an update as things proceed. And to correct a mistake, that is a CT-7 in the system, not TFM-35. Thank you once again for the cordial advice and hospitality.
