Bob K's 300B System System
Last Update: May 24, 2005 at 16:12:56 IP Address:
Amplifier: *Welborne Labs Laurel IIX amps, with ultimate upgrade, using Svetlana 300Bs. I had been using the Laurels as my primary amps since late 1999, and they are glorious.

*World Audio Design headphone amplifier, wired for high impedance headphones. I know I substituted a number of designer parts, but I don't remember what.

Preamplifier (or None if Integrated): *Welborne Labs Reveille (active) preamp, with parts upgrade.

*I sometimes substitute an Electronic Tonalities 'Bottlehead' Foreplay clone, which has a number of modifications: upgraded power cord, Anticipation, Welborne 100K stepped attenuators, Caddock resistors, Hovland coupling caps, 'snubber', and I've added tape out jacks, through which I can run a headphone amp and headphones, to which I listen early in the morning.

Speakers: *Pi Speakers Theater 4 speakers

*Adire Audio Tempest sub

*Various DIY speaker projects, principally single-driver designs with Fostex drivers.

*Sennheiser HD 600 headphones.

CD Player/DAC: *CEC 3100, used as a transport, connected by AES/EBU to

*Assemblage DAC 2.5

Turntable/Phono Stage: *Rega Planar 3 with Sumiko Blue Point cartridge

*Audio Electronic Supply PH-1. An absolutely wonderful phono stage, slightly warm but clear as a bell, produces three-dimensional image.

*ASUSA PP-1. I occasionally substitute this phono stage, usually in another system (with the Foreplay). Not quite the equal of the AES.

*Welborne Labs Reveille Phonostage. I've listened only briefly to this newly-completed (8/01) unit. Initial impression is extremely fast and punch, but without that solid state harshness. Now I have to figure out what to do with it.

Other Source(s): Parasound T/DQ-1600 tuner
Other Accessories/Room/Misc.:
Speaker Cables/Interconnects: *Speaker cables are Jon Risch recipe using Belden 89259 and WBT spade terminations

*Interconnects are Jon Risch recipie using Belden 89259 and Vampire connectors

Other (Power Conditioner, Racks etc.): *Welborne Labs Gatekeeper II

*Premier stands

Tweaks: None really. I try to keep the various cables separated to the extent possible.
Room Size (LxWxH): 24 x 12 x 8
Room Comments/Treatments: One long wall contains a 6' cutout from waist height to the ceiling, facing into the kitchen and adjoining sun room. The room contains no treatments per se. 'Treatments' include an area rug, bookcases, CD racks, a sofa and large Amish quilt on one of the short walls.
Music Preferences and Comments:
Music Used (Genre/Selections): Here's where the fun begins.

*Classical: Although I enjoy everything from Perotin to contemporary, I am less enamored of much of the standard 19th Century repertoire (although I have a weakness for Brahms). Things pick up again beginning late in that century (Bruckner, Mahler, Strauss} and on through the really weird stuff that follows. To avoid a proliferation of categories, I include here contemporary computer music.

*Opera: Here I get really picky. I love some Baroque (Lully, Rameau, less so Handel) and then skip to Wagner, Strauss and Puccini.

*'Classic' Rock: Most of my LP collection dates from the late 60s to mid 70's, when I was in high school and college, at which point I was listening to rock almost exclusively. I still pull out and enjoy Jimi, Janis, Cream, et al. Although he should probably be in a separate category altogether, I include here Frank Zappa and the Mothers. I stumbled across 'We're Only In It For The Money' in ninth grade and was hooked. I'm convinced that early exposure to FZ permanently warped my brain and accounts for my current eclectic tastes.

*My latest foray is a very selective dip into Rap. At the moment, I've gone crazy for Eminem, who is hilarious.

*Selected 'World' Music: Indian, Pakistani (the great Nusrat Fateh Ali Kahn), Laotian, Balinese and a few others.

*'Old Time': My latest exploration, which in my mind includes all sorts of widely varying genres, from hillbilly to Black and White spirituals to Delta blues.

System Goals/Comments: My first good system was solid state. Although it was crystal-clear and a vast improvement over my college gear, after a few years I found my listening decreasing. Eventually, I found the answer, for me at least, in tubes. Coincidentally, for reasons I still don't fully understand, I was bitten by the soldering bug, and tried my hand at a kit because I have no science or engineering background or aptitude. Since then, I have been working to assemble a kit-based system that is detailed but also has the intangibles necessary to make music listening truly enjoyable.
System Strengths: The combination of the Welborne SETs and the Pi Theater 4s is magical. Smooth yet detailed, I can listen all day without becoming fatigued.
System Weaknesses: Although the Pis are capable of deep bass with more powerful amplification (e.g., my 40W Assemblage ST-40), the Laurels roll off the last octave or two. I've therefore added an active Adire Audio Tempest sub, crossed over via a Marchand xover. Pictures of the sub in progress are available at http://www.audiocircle.com/circles/modules.php?set_albumName=album54&op=modload&name=gallery&file=index&include=view_album.php
Video/HT System: Separate
TV/Projector: A 27" Sony -- Don't know the model.
Processor/Receiver/Amplifiers: *Processor is an Outlaw Audio 950. Although I've seen reports about reliability problems, mine has worked flawlessly.

*Amps are a hodge-podge of old ss units -- Classe and Acurus.

Speakers (Center, Surrounds, Sub): A hodgepodge. The sub is another diy Adire Audio tempest.

*The sub is a DIY Adire Audio Tempest, downfiring in a 21.5' sealed box, with an AVA 250 plate amp.

Sources (DVD/VCR): Yes -- don't know what they are.
Comments on HT System: The addition of the sub has made the system a lot of fun.
