Allan Moyse's System
Last Update: March 30, 2007 at 10:25:30 IP Address:
Amplifier: Tri-amplified:

Bryston 3B-SST for highs
Bryston 4B-SST for mids
Bryston 4B-SST for lows

Preamplifier (or None if Integrated): Sonic Frontiers Line-3 Special Edition, equipped with some very tasty NOS tubes and upgraded volume control ICs.

Accuphase F-25 Frequency Divider (Active Crossover); 3-way configuration, crossed over at 350hz and 2500 hz. (I have numerous other frequency boards on hand for tweaking)

Speakers: Custom dipolar (open-baffle) main speakers, each utilizing one Skaaning 13-inch SK300 Woofer, four Dynaudio 17W-LQ Esotec Midranges, and one Dynaudio T-330D Esotar tweeter. The Midranges and tweeter are in MMTMM configuration on one baffle with the woofer on a seperate baffle.

2x Genesis 928 Servo Subwoofer. The subs are modded with Muse and Black Gate capacitors in the power supply.

CD Player/DAC: Pioneer Elite DVL-91 DVD/LD/CD player - Heavily Modified (Black gates, FRED rectifier, mechanical dampening, Vampire connectors, true 75-ohm BNCs, etc.)

Sony SCD-1 with various Audiomod upgrades (Superclock, Vishay resistors, Black Gate caps, Burr-Brown Opamps, & Audiocom regulators)

Turntable/Phono Stage: Rega Planar 25 turntable

Benz Micro Glider cartridge

Sonic Frontiers Phono-1 phono stage

Other Source(s): none
Other Accessories/Room/Misc.:
Speaker Cables/Interconnects: Speaker Cables:


High: Kimber Kable 4TC with Postmaster spades

Mid: Kimber Kable 8TC with Postmaster spades

Low: Kimber Kable 8TC with Postmaster spades



Preamp to Crossover: Silver Audio Hyacinth Balanced

Xover to Amps (all three positions): Silver Audio Hyacinth Balanced

Preamp to Subwoofer: Kimber Kable PSB

Phono Stage to Preamp: Silver Audio Hyacinth

CD Player to Preamp: Silver Audio Hyacinth Balanced

Other (Power Conditioner, Racks etc.): PS Audio Power Plant 300 for source gear (except turntable)

2x PS Audio Duet Power Center: One supplies the TV and the Crossover. One is on the Bryston 3B-SST (Highs).

3x PS Audio UPC-200: One each on the Genesis subwoofers. The other supplies the Preamp, Phono Stage, and Turntable.

Custom built power supply for Accuphase F-25, has two stages of transformer isolation and noise filtering. This unit also supplies the 100VAC for the Crossover as it is a Japanese unit.

VPI record cleaning machine

DIY 'flexi rack'

2x Sound Organisation rack (room for future expansion)

Tweaks: The listening room has a dedicated 80-amp electrical subpanel for audio use only. All circuits are 20 amp, wiring is oversize spec with hospital grade outlets, and a dedicated ground spike located just outside the room.

Cardas RCA Caps on all unused jacks

DIY Vibration isolating racks for LD player and amplifiers. They are a lot like the 'Flexi Rack' design, but have only three vertical rods (two in the front, one in the rear). The shelves are made by laminating 3/4' MDF with 3/4' Interior grade plywood.

Room Size (LxWxH): 22 x 14 x 8
Room Comments/Treatments: This room is far superior to my old room in size, noise control, and acoustics. It has fully floated double-thickness walls with blown cellulose insulation (BBC style, STC 58-60 DB). The only door is heavy solid wood, and the windows are all double-glazed. This does a great job of keeping 'outside' noise out. It also means that one can enjoy listening at high volumes without disturbing the rest of the house.
Music Preferences and Comments:
Music Used (Genre/Selections): Classic Rock, Hard Rock, 60's-80's Rock/Pop, Japanese Rock/Pop, Classical, New Age, Metal, Female Vocals

System Goals/Comments: My goal is to build an excellent system to serve two purposes: 2-channel music reproduction (#1 goal) and, a home theater setup for Japanese Animation. My emphasis is on musical reproduction that's very dynamic and clean, with solid bass extension.
System Strengths: Preamp is simply the greatest I have ever heard! Ditto for the crossover.

Amplification is wonderful--clean and powerful.

The speakers are truly incredible. They have excellent detail in the upper regions (to be expected from the Esotar Tweeters), and rock solid bass reproduction.

System Weaknesses: I'm very happy with the audio in general, but there are a few areas that could use improvement:

This listening room is a major improvement over my old one (which was too small and oddly shaped), however the room needs some more attention to treatment as it is a little bright. I think some carefully placed diffuser panels will help greatly.

I am satisfied with my analog setup, but some other equipment could use upgrading, mainly the LD player.

The 'sweet spot' listening position is fairly small, due to my room arrangement. This is fine for one listener, but it's difficult to have multiple people really enjoy the system at the same time as the difference in performance at the optium seating position and elsewhere in the room is extreme.

Video/HT System: Integrated
TV/Projector: 32' Sony FD Trinitron WEGA XBR KV32XBR400 with Digial Reality Creation
Processor/Receiver/Amplifiers: Same as above
Speakers (Center, Surrounds, Sub): Same as above
Sources (DVD/VCR): Pioneer Elite DVL-91 CD/LD/DVD (same as above)
Comments on HT System: Overall performance is very good given the space I have to work with. The video performance is excellent with normal film sources and most animation, but I'm a little unhappy with what the Sony's DRC circuitry does with some source material. Now that the Wega is getting on in years I am searching around for a replacement. As you can tell from my component choices, I am much more interested in good sound quality than 'the theater experience'. I like a nice clear picture, but I'd rather concentrate on 2-channel sound as opposed to fancy surround systems.

As a quick note, the PS Audio A/C filter made a stellar improvement in video quality on the WEGA.

Of course, with no surround decoder or speakers, audio performance with modern films could certainly be improved.

Other Interests/Hobbies/Occupation: Motorcycles, Cars
