David Berning Co. ZOTL Pre One Special Upgraded Version
David Berning Co. ZOTL Pre one serial #13043T featuring many special upgrades performed by North American factory authorized Berning modifier Kris Kosiba / Lakeview Audio. Many significant upgrades including the following: Cryo treated Oyaide IEC, Patented Stillpoints isolator circuit board stand-off's, V-Cap grounding caps, Shielded power wire, Capacitive upgrade, ALL factory wiring replaced and upgraded with cryogenically treated continuous cast OHNO Pure Copper oxygen free long drawn wire, naked Vishay damping resistors, and upgraded vacuum tubes. The upgrades as listed represent well over a $2000 additional upgrade by itself. These critical upgrades take the Berning Pre One to a truly reference level of playback capability. Noise floor is significantly reduced, the capacitive upgrade and damping resistor change improves dynamics and PRaT dramatically. The OHNO pure Copper wiring upgrade by itself results in massive gains in overall clarity, tonal weight and body. This preamp is in excellent shape and is equipped with the optional RIAA phono section and has Jensen SUT transformers installed ready to play low output moving coil cartridges. Worldwide voltage 110v/120v ~ 60Hz and 220/240v ~ 50Hz compatible input. Lastly, Stillpoints AL isolation footers set of 3/ea. included.

TASCAM 42B 1/4” 2 track broadcast grade open reel-to-reel tape player
Near mint condition unit completely refurbished by well known industry professional Soren Wittrup (CS Electronics). Tape handling electronics are his own design so that this device handles tape in similar fashion to a big Studer, in other words, it is extremely gentle on tape. Balanced XLR inputs/outputs only.
Unit also has a custom switch on the back which allows an external tape head preamplifier to connect direct to the playback head bypassing the internal playback electronics. Playback electronics are custom and will exceed most external head amps playback capabilities. This unit also has a high end Furutech IEC input on the back in place of the stock captive power cord. Physical aluminum chassis has been custom repainted, including the stand by Artisan Fidelity. The "TASCAM" sticker on the stand was removed, that is actually paint you see in the picture.
Stock glass fuses have been replaced with AMR Gold MK II fuses. The unit also includes the infrared remote control option which allows start/stop, (fast)rwd ~ (fast)fwd and library spooling in both directions. The factory stock standard yellow (read: old looking) meter lighting was upgraded to a custom blue lighting which appears more modern. The EQ is CCIR but can be internally switched to NAB. Soren worked out the circuit to add a switch so that it can be externally switched between the two EQ’s.
Transit will be rather costly due namely to size. Buyer must pay for insurance, packing, shipping and PayPal fees. A custom built wood shipping crate will be required to ensure safe transit.

LaHave Audio Avaaza RAAL Ribbon Italian Ebony finish
Rarely seen LaHave Audio Avaza RAAL Italian Ebony for sale carefully hand crafted in Nova Scotia, Canada by designer Jim MacCleave and former RF Engineer Fred Conlon. LaHave Audio is a little known but growing company who has been quietly designing superbly musical and accurate loudspeakers for 30 years. The Avaza RAAL have been my defacto reference loudspeakers for the past couple of years, and possess a combination of musicality, tonal balance and see through transparency few can rival anywhere close to this price point, which is typical of LaHave’s loudspeaker design philosophy. The Avaza design features a time and phase aligned array utilizing a RAAL ultra high bandwidth true ribbon dispersion tweeter mated seamlessly to a Seas Prestige Full Range Papyrus fiber 8" driver, air core inductors and premium resistors. The RAAL tweeter may be used, or may be completely disabled, depending upon personal preference and room acoustics. The full range speakers completely disappear when playing within the room and possess zero box coloration’s, they are nearly the definition of transparency. Timbre, tone, vocal presence and clarity throughout the midrange frequencies is simply superb and transients lightning fast with visceral bass impact. The RAAL wide range ribbon (dispersion application) possesses an airy, electrostatic like characteristic, due both to its extraordinarily low moving mass and wide frequency response (2kHz - 100k Hz Flat). Condition - Age roughly 3 years - Rated a conservative 8/10 cosmetic condition, but closer to a 9/10. Operationally rated a 10/10 condition, no issues whatsoever and were never over driven, stored in a pet free/child free/smoke free environment and driven exclusively by David Berning ZOTL vacuum tube amplification. Includes wooden shipping crates custom built by LaHave Audio. Total shipping weight roughly 450lbs (2ea. containers) Pick up welcome, I am located roughly 35 min. from downtown Chicago.

David Berning Co ZOTL Custom Mono Amps and Berning Octal Preamp
Very rare opportunity. One-of-a-kind pair of custom made, bespoke David Berning Co. pure vacuum tube ZOTL mono block amplifiers and Berning Octal capacitance coupled pure vacuum RIAA + Line level preamp with external power supply for sale.
I can guarantee you will not find another pair of Berning ZOTL vacuum tube mono blocks quite like these. They are amazingly musical, transparent and dynamic with authority plus amazing drive. David Berning is a genius designer who has remained at the forefront of cutting edge vacuum tube amplification since the mid 1970's. These have been my personal reference amplifiers for a number of years and are supremely reliable, having never required any service. For personal reasons, I have decided to reluctantly offer them for sale to the right discerning buyer and music lover. These over engineered ZOTL mono amplifiers as you may guess from the photographs are very powerful with enormous headroom. Berning ZOTL amplifiers are renowned for delivering musicality, raw lightning fast dynamic transients, power, thunderous low bass authority and articulation with refinement in spades. Many special upgrades almost too numerous to list. Refer below for some details about these extraordinary, ultra reliable vacuum tube amps.
Together with the mono blocks, this is a rare opportunity to own a bespoke custom made, point-to-point wired David Berning Co. octal pure vacuum tube preamplifier with built in passive RIAA phono section section and outboard resonant switching vacuum tube power supply. Unlike Berning's later preamp offerings, this is a capacitance coupled design offering even greater midrange weight, palpability and body. Features many hand selected upgrades and component options. The line stage features NOS 6SN7 octal vacuum tubes with NOS 12SF5 tubes in the phono section. Playback is dynamic, clear and lively, offering a true 3D holographic dimensionality, with solid imaging and an open, grain free musicality with simply wonderful timbre and tonal characteristics. As an octal tube based design, this Berning Preamp requires a high quality, heavy, high mass equipment rack to perform at its best.

Technics Sp10Mk.3 NGS Direct drive
Mono and Stereo Magazine review Quotes by Richard H. Mak
“There is no music better to demo the NGS than Batman’s own music, or should I say Hans Zimmer and James Newton's original soundtrack “The Dark Knight Rises”, the bass notes on track Underground Army is not just chest pounding, but earth shattering! It reminds me of the sound of the thumper which the Fremens use to summon the Sandworm on the planet of Arrakis (a scene in David Lynch’s 1984 movie DUNE). It is the deepest “thumping” which I have heard from any turntable, including my personal reference TW Raven AC, and the VPI Titan which I recently review. It literally shakes the foundation of my listening room with solid deep bass “thumping”.
“The same explosive dynamics is carried onto The Battle on Ice in Prokofiev’s Alexander Nevsky with Thomas Schippers directing the NY Philharmonic (Columbia Masterworks MS-6306), on a lesser table, the recording can easily be turned into a garbled up mess, combined with ear-piercing edginess on the highs. The sound remained composed, with clear instrument separation and solid holographic projections. The weightiness of the instruments makes the presentation more forward, immediate, yet the acoustic space remains layered and three dimensional. It throws musical elements in all directions, creating an ever-expanding soundstage with vivid colors, and high contrast.“ Read full review here (Link)
