Current, please, no voltage
It is worrying that, against all odds, audio amplifiers of all kinds, try to drive the loudspeaker with the voltage instead of current, claims Finnish electronics engineer Esa Meriläinen in his book Current Driving of Loudspeakers.

Gudebrod 3T12V Preamplifier
$5500
3T12V is a single ended stereo line level input tube preamplifier.
The heart of this tube preamplifier we utilized a 274b rectifier also making it possible for you to roll tubes like a 5u4 or 5r4 rectifier.
The signal tubes are also capable of being rolled for that one of kind sound. We're currently using Psvane 274b-t mark 2, 12au7 genalex gold lion and a pair of Phillips Jan 12at7wc’s.
Paired with beautifully crafted Lundhal chokes and output transformers it allows our tube preamplifier to sing!
The Wenge wood sides are standard.
Comes with 6’ 14ga. Power cord.
Warranty is 2 years parts and labor, tubes 90 days.
All preamplifiers are made to order and take 3 weeks from date of purchase and are run for 100 hrs. before being shipped.
If local to the Illinois area we also offer in home demo's and installation at no additional charge.
Specifications:
Directly coupled on hand-crafted turret boards
Non-inverting
High input impedance, low output impedance
Auto channel balancing compensates for aging tubes
Ground lift switch
Frequency response: 20hz - 50khz
Gain: 5x (15db)
Harmonic distortion: <.05% in normal operation
Power Consumption: 17ma
Main Votlage: 120vac
Inputs: 3 single-ended
Outputs: 1 single-ended and 1 balanced (true 600 ohm load)
Dimensions: 19" x 15.25" x 4.75"
Weight: 25 lbs

ATC SCM150 ASLT LE
The 3-way system comprises the SCM150ASLT speaker towers incorporating the latest ATC designed and built drive unit technology, combined with an ATC P6 power amplifier.
Manufactured by ATC’s own cabinet makers, weighing 116kg and at approximately 1.4m tall, each speaker enclosure is finished in selected European crown-cut walnut veneer with a high-gloss polyester lacquer, and detailed with a stainless steel badge, input panel and bespoke limited edition plinth, PVD treated to create an exclusive nickel-like appearance.
Deploying proprietary drivers throughout, the 3-way system uses ATC’s new SH25-76S tweeter, featuring both upper and lower suspension for greater operational precision and lower distortion; the latest evolution of ATC’s signature soft dome midrange design, the SM75-150S, and the company’s low-distortion SB75-375SL Super Linear bass driver.
Combined they deliver a response accuracy of ±2dB between 60Hz-17kHz and ±6dB from 25Hz to 22kHz across a wide horizontal dispersion and at a maximum SPL of 117dB. The rear-mounted input panel features a single LEMO aerospace-grade 10-pin connector.
The P6 is a high-performance Class AB dual-mono power amplifier designed and built by ATC to provide dedicated amplification and optimally matched active crossovers for the SCM150ASLT. It features a total of 6 channels: 2x (200W LF, 100W MF, 50W HF) for a combined output power of 350W/side. Generating a signal-to-noise ratio of more than 105 decibels its ultra-low noise discrete design, paired with 3-way active crossovers with phase equalisation, offers ‘clear and detailed audio reproduction’. On the rear panel, professional L/R XLR inputs (from preamplifier/digital source) are joined by aerospace-grade LEMO multi-pin loudspeaker output connectors.
As is customary with ATC products the SCM150ASLT and P6 are covered by a six-year warranty.
Typical retail price (inc VAT): £46,600 pair
Available to order immediately. Product built to order, earliest shipping Wednesday, August 5th.
