* ****************************************** * "Most Outstanding Rooms at the Show." Stereotimes magazine writer Michael Wright picked the Granite Audio room as one of the "Most Outstanding Rooms" at the 2005 CES Show. Stereotimes CES 2005 show coverage "Now let's talk about the music rooms. Having been an avid reader of quite a few of the competing periodicals and web-zines I have a pretty good idea of what fellow reviewers like in terms of exhibitor rooms and it's typically the usual stuff, i.e. Jeff Rowland, Krell, Thiel, etc. What I shall do here is give you my picks for the "Most Outstanding Rooms at the Shows." These were the rooms of . . . . companies that I genuinely enjoyed being in and who I feel don't get the amount of recognition they deserve." "I found myself having a good time listening to music in the Granite Audio room. Everything in their room, except for the wonderful sounding Von Schweikert Research VR4jr, was made by Granite. The VR4jrs were driven by the Granite 864SR KT-88 monobloc amps, Model 770 tube preamp and Model 657 tube CD player. All interconnects, speaker cables and noise suppression was by Granite as well. The sound here was lively and dynamic with a tonality that gave performers a "you are there" quality that was refreshing." by Michael Wright * ****************************************** * Equipment Lust in Las Vegas: Day Four The 2002 International CES Show Greg Weaver, Stereo Times Magazine 11 February 2002 "Having heard so much about Don Hoglund and Granite Audio, I deliberately made my way to his room. Don was showing all his own products, source to cables to speakers. The source was his Sony based Model #657 CD Player ($2900), which in turn fed his Model #770 preamplifier ($4900). His gorgeous looking and sounding Model #861 DECO ($24700) amps have a full Granite enclosure and were driving his 3-way Model #280 Loudspeakers ($15,700). All cables were Don's designs as well. I finally was able to see what all the fuss was about. This room sounded wonderful. and we continued to listen to some rich, wonderful sound. Don has much to be proud of, and his entire system approach also has much to be said for it. If you get the chance, go out of your way to give this equipment a listen. You won't be sorry." Greg Weaver * ****************************************** * "CES Expensive Tubes" Jonathan Scull, Senior Contributing Editor Stereophile May 1999, Page 61 "Their (Granite Audio) tubed electronics and speakers are encased in the many-hued stuff (acrylic-granite) that's said to offer good inherent damping characteristics. These are quality tube designs; you'll find Vishay, Holco, Sprague, and other audiophile parts scattered throughout." * ****************************************** * MSRP with the $500 0.3 Upgrades and $200 backlit blue logo is $5,700.00 Pair. These amps can be upgraded to 0.7 or 0.8 for an extra fee prior to shipping. I also have an extra pair of plain Opal color granite faceplates without any logo that I can put on the amps in place of the Sandstone faceplates, at no extra cost to you. The Opal color is a black sandstone look. Output power - 60 watts Pentode , 30 watts Triode Tubes - 2-KT88, 2-6SN7, 5R4-WGB Optional Tubes - Will also run on 6550A, EL34, 6L6GC Power Consumption - 220 watts with removable IEC cord. Contour - Three user adjustable settings. Speaker Impedance - 4, 8, 16 ohm with separate posts. Frequency Response - 9Hz - 48KHz with zero feedback, triode mode. Signal to Noise - -90dB at &.7 volts output. Switches & Contacts - Gold or silver over OFC copper, or solid silver. Bias - Simple user adjustable with factory tool. Dimensions - 9" W x 16" D x 9" H Weight - 30 Pounds each. * ****************************************** * This amp can run without a preamp! Simply plug your CD player directly into it. The 861.3 has a 100K ohm constant impedance Alps input volume control for just such a simple system! The CD player "sees" a constant high impedance load at all frequencies. The 861.3 has zero feedback, and there is a bipass circuit for user adjustable contours. When the contour circuit is not used, there is nothing extra in the circuit. The contour loop has no switches or connections in the signal path when not in use. The zero feedback design is much more challenging for the designer, but equally more enjoyable for the listener because of the increased dynamic range and excitement of live present-sounding vocals, as experienced by Larry Greenhill of Stereophile Magazine at HI-FI '98. "I was drawn to their room by the stunningly realistic sound of Eric Clapton's voice." Why tubes? A tube is a true valve. A transistor is a switch. Tubes let the music flow, while transistors are incessantly turning your music on and off by their very nature. Ever notice how the water flows smooth from conventional shower heads while it pulsates from massage heads? The on-off pulses feel good on your back, but they're harsh on your music and add to listening fatigue the same way your back gets numb to the water pulses after a while. The tube filaments are run on AC voltage which is lifted from ground by 40 volts DC, and wired with shielded twisted pair wires for maximum current handling, minimum noise, and a smooth voltage rail. Switches and contacts are either gold or silver. Tube biasing is user adjustable with factory supplied tool and Vishay trimmers, all easily accessed from the rear of the chassis. The amp is easily switchable from pentode to triode with an 18 amp solid silver contact toggle switch located between the KT88's. The amp develops a minimum of 60 watts in pentode and 30 watts in triode. If the user has efficient speakers, the triode mode offers some excellent dynamic sound. The RCA inputs and speaker outputs are hard gold plate over silver over copper for the best in long-life wear and maximum transfer of a clean unaltered signal. SO, HOW DOES THE ZERO FEEDBACK 861.3 SOUND? Live, immediate, present, dynamic, detailed. At CES we were shaking the suite below us at the Alexis Park with the deep bass battle drums from "Braveheart" and only 30 watts! We custom design our products to make it sound like you are on the stage with the performers, listening to real live vocalists and real instruments. "Hi Don, Wanted to let you know that my Power amps arrived safely...They're both physically and sonically beautiful... the cd to amp option (bypassing preamp) is working very nicely... the upper and lower extension is far beyond what I was previously experiencing, and the midrange,...ah the midrange... I will have to eventually find the appropriate adjectives... I was up until the early hours last night listening to Diana Krall & Patricia Barber... intoxicating!! " Greg G. Reston, VA. When you listen to Diana Krall play the piano on our system, you will feel like you are sitting at the bench with the bass strings vibrating on your left and the melody running up and down the keyboard octaves on your right, with Diana sitting on top of the concert grand piano singing to you in person. You will hear the delicate smack as she parts her lips, draws a breath, and sings "I'm Through With Love" to you in person. You don't just hear our 3-dimensional sound stage, you're on the stage involved in the live performance. GET A GRANITE AUDIO SYSTEM AND BE THERE. * ****************************************** * ".3" Upgrade. Input Circuit. Make the input grid stopper a fixed value. Add grid bypass to V1-6SN7 tube. Modify volume control circuit. This upgrade adds only 2 resistors to the music signal path. This upgrade lowers the system noise floor, gives some sonic improvement, and makes the volume control work better. Prior to the upgrade you may have noticed that the volume control would interact with some brands of 6SN7 tubes in the V1 tube socket. Prior to this upgrade it was necessary to use only the highest quality tubes in the V1 socket. This upgrade will cure that issue and allow you to use a wider selection of available 6SN7 tubes in the V1 socket. It will also lower the signal-to-noise to -90dB. MSRP $500.00 pair
