The Magnepan Altar: Realization

by nils on Ever Evolving
The Magnepan Altar

Description

The Magnepan Altar represents hundreds of hours of research and work.

The Realization of the Altar is a permanent and uncompromising modification to the Magnepan 3.6R.

Triamplification is simply three channels of amplification per speaker, or in the case of the Magnepan 3.6R, one per driver. The lack of passive components (i.e. capacitors and inductors) between the amplifier and the driver results in a true, uncolored sound that few have experienced.

Thank you for looking! I'd be happy to answer any questions about this system or the modifications.

Components Toggle details

    • Magnepan MG-3.6r
    Rewired for triamplification. Each driver is connected to Vampire BPHEX binding posts using Goertz MI1 (custom integrated terminations treated with progold and silclear to prevent oxidization)
    • Audio Concepts Titan II LE
    Very musical sealed enclosure subwoofer. Class AB amp. A perfect match for Magnepan speakers. Connected via direct input (active crossover employs a 45hz fourth-order LP).
    • Quicksilver V4
    I use four of these to drive my midrange panels and ribbons. Two have been upgraded by Response Audio; two are stock.
    • Bryston 7B-SST
    900wpc into 4. In the fashion of obscene overkill, these drive only my bass panels. Probably the best amps for this job.
    • Marchand XM44 4-way crossover
    Highly flexible active crossover used to triamp my speakers and filter the frequencies for the subwoofer (better than the crap xover built into most subs). Currently enjoying 35hz LP, 240hz LR4, 1700hz LR4 filters.
    • Bent Audio TAP-X
    Autoformer-based preamplifier. Probably the last preamp I will ever buy.
    • Marantz SA-11s2
    One of the best SACD players out there!
    • Analysis Plus Crystal Oval
    1m RCA CD player to preamp
    1m XLR preamp to amp

    These cables are highly resolving and neutral. Wonderful match for my system.
    • Analysis Plus Solo Crystal
    4' runs from each monoblock to the speaker. Oh, and locking banana plugs rock. :)
    • VH Audio Flavor 2, 3, 4
    Flavor 4 power cords for the amplifiers and Equitech 2Q; Flavor 3 for the SACD player; Flavor 2 for the active crossover.
    • Mapleshade Samson V1
    I chose Mapleshade primarily for the stunning aesthetics. * Samson V1 stand with extra shelf and riser nuts. * (2) 15" x 18" Amp Stands * (2) 12" x 15" Amp Stands * (1) 18" x 24" x 4" Amp Stand * (2) 15" x 18" Platforms
    • GIK Acoustics Various treatments
    If you have a nice system, you're doing yourself an INCREDIBLY injustice to put it in an untreated room. * 4' x 8' array of D1 diffusion panels (painted to match my apt!) * 4 Tri-Traps stacked floor to ceiling * 244 panels at the sidewall and rear wall first reflection points.
    • Mye Sound MG3.6 aftermarket stands
    These are leagues better than the silly 'T' brackets that Magnepan supplies.
    • RealTraps MicroTraps, MiniTrap HFs
    Used to treat the side wall and rear wall reflections, respectively
    • ASC StudioTrap, SoundPanel
    Additional acoustic treatment for voiced diffusion and absorption
    • Oyaide R1
    Purchased with cryo and burn-in treatment from VH Audio. Outlet cover is Furutech 103
    • Equitech 2Q
    I use two of these: one for the tube amps hooked up to a dedicated 20A circuit, the other for the front-end + Bryston amps. I modified one with 3 x Oyaide R1, 2 x Furutech FP-15a (cu), VH Audio wiring, and no GFCI.
    • Herbie's Audio Lab Iso-Cup / Lampblack footers
    These work wonderfully under my tube amps.
    • Herbie's Audio Lab SuperSonic tube dampers
    I can't live without 'em!
    • Herbie's Audio Lab Grungebuster CD Mat
    I didn't expect too much from this tweak, but I was oh so (happily) wrong.
    • Audio Points 1.5APD
    Used under my power conditioner with Herbie's decoupling grounding base.

Hi Nils!
Nice system! I had 3a´s and now 3.6´s and just love them. My Mye stands are on the way from Canada and I just installed the Cardas kit! I use BAT VK-40 and VK-500 and I have a great soudstage with fantastic bass, don´t need a sub! But I want to soften up the treble so I´m really intrested in Your room tweaks and fuses! Do You think You can get hold of them in Sweden?
Best regards
Persve ( from Sweden )
