Neve 1073LB &
1073LB EQ
The Creamer was designed specifically to introduce creative coloration to microphone signals through hybrid technology,
carefully blended to form a cohesive but versatile whole. Deliberately coloured preamps provide an antidote to the
perceived 'sterility' of digital recording, but there's 'good coloured' and 'bad coloured'. The trick, of course, is to find the right
blend of properties that delivers subjectively 'good' sound colorations. The Creamer is based on a configurable valve circuit
(triode or pentode) with an input transformer, a solid­state buffer, and selectable solid­state or transformer output coupling, a
combination that allows the sonics to be shaped in four distinct ways.
Available in two primary forms, the Creamer Plus model incorporates dedicated rear­panel transformer­coupled line inputs
and some additional tone­shaping EQ options, which are omitted from the Standard version. The red front panel of both
units is distinctive and attractive, with white­edged black ovals denoting the two channel sections, and clear white labelling.
The controls for each channel comprise eight sturdy push buttons, five miniature toggle switches, and a shiny chicken­head
knob.
Signal Path
Mic and line inputs are connected on rear­panel XLRs, and unbalanced instrument inputs are via front­panel quarter­inch
jacks. A Line/Inst button selects the line input unless an instrument is plugged into the front socket (this button is labelled Hi­
Z in the Standard version). Phantom power is also switched from the front panel, as is a 15dB pad for the mic input. The
latter plays an important role, as the input signal level affects the sound character of the Creamer's valve gain stage.
An oversized 1:10 ratio Cinemag mic­input transformer is employed for its high saturation threshold as much as its sound
character, while the line input uses a separate 1:1 transformer. The instrument input goes directly to the valve, with an input
impedance of 2.2MΩ.
The mic transformer normally provides 20dB of gain, but a front­
panel button, labelled +6dB, reconfigures its windings to drive
the valve a little harder, if desired. The side­effect of this
reconfiguration is that it simultaneously decreases the
impedance by a factor of four and, since the Creamer offers

options are 900Ω (low), 2.4kΩ (medium) and 10kΩ (high) as
standard, while engaging the +6dB mode provides 225Ω, 600Ω and 2.5kΩ instead. Selecting the input pad fixes the input
impedance at about 2.5kΩ. Different input impedances affect the tonality of most dynamic and some transformer­output
capacitor mics, so this can be thought of as another creative tone­shaping tool.
An EF86 (low­noise pentode) valve fixed­gain stage operates in Class­A with negligible negative­feedback, and the circuit
is switchable between triode and pentode configurations for different distortion characteristics. With minimal negative­
feedback, the inherent non­linearity produces quite significant amounts of distortion — which is all part of the intended
musical coloration. In triode mode, it provides a modest 14dB of gain, rising to 21dB in pentode configuration. However,
a 'Gain Up' button bypasses the valve's cathode to increase the gain by 4.5dB (triode) or 9dB (pentode), and in the Plus
model the cathode circuitry also includes switchable inductors and capacitors to provide two gentle LF (Fat) and two slightly
stronger HF (Air) shelf boosts. The Fat settings deliver boost from 400Hz or 600Hz, while the Air boost is from 2.2kHz or
7kHz. The amount of boost is normally 4.5dB in the triode mode and 9dB in pentode mode, but these can be reduced via

internal trim pots if required. Setting the Fat and Air toggle switches to their midway positions provides a flat response, and
this EQ is also disabled when Gain Up is selected. The line and instrument inputs provide up to 13dB of gain in triode or
20dB in pentode modes, and unity gain is achieved with the level knob at about 12 o'clock and 10 o'clock, respectively.
A continuously variable attenuator sets the level feeding the Cinemag output transformer or discrete complementary­
transistor balanced output driver, the rear­panel line output being derived from one or the other via a front panel push­
button. The Plus model I received for review was equipped with an extra toggle switch, marked 0 and +6dB on the review
model, that was supposed to reconfigure the output transformer. The manual claimed that it provided an additional 6dB of
gain on the transformer output, but in fact it delivered a whopping 16dB boost regardless of the output mode selection. As
we were going to press, Sonic Farm told me that they've revised this on current production models, so that this switch
instead offers 0, ­6 and ­12dB attenuation, which seems more useful. The output transformers fitted in the review model
('Creamer A') had Ni­Fe cores, but a steel­cored option ('B') is available, or you can have one of each in the two channels
('AB'). The final push­button implements a polarity reversal at the output.

Overall, the maximum possible gain is a mammoth 74dB in pentode mode and 60dB in triode mode (this remains the same
on the version with the reassigned toggle switch), while the minimum (with the level knob fully up and only the pad selected)
is 25 and 18dB, respectively. The rotary level knob allows the signal to be faded out completely, if required. The overload

noise ratio was 108dB (A­weighted) and the noise floor averaged ­82dBu.
Just to complete the front panel description, a bi­colour LED
provides simple level metering, showing gain­stage overload
(red), and a progressively brighter signal­present indication
(green), which starts to illuminate about 43dB below the
overload level. A blue LED next to the Tube Mode button
indicates the presence of the heater supply voltage, and serves
as a power­on light. A large, round mains­power rocker switch is on the right of the front panel, while the rear carries an IEC
mains inlet, fuse holder and ground­lift switch. The unit is wired for 115VAC or 220­240VAC mains supplies at the factory,
and overall power consumption is given as 30W.
Impressions
The Creamer provides four distinct operating conditions: triode or pentode, with solid­state or transformer outputs, plus
options to vary the drive level into the valve and into the output transformer. A lot of valve preamps are 'one­trick ponies', but
the Creamer offers several genuinely useful and distinct tonalities. The pleasing pentode coloration retains a sense of
natural presence and detail, while sounding a little brighter, with a tad more transient emphasis, than the triode mode,
although the latter still sounds immediate, clear and very musical. Selecting the output transformer adds a little more 'iron'
and weight to the sound, providing a useful alternative to the solid­state output, although it is sensitive to the load
impedance (as all transformers are).
This isn't what anyone would call a 'clean' preamp: it's not like a GML or a Grace Design, not even at the gentlest settings —
but it is always wonderfully appealing and musical, adding a relaxed sense of life and character to every source. The more
I used this preamp and compared it with my familiar references, the more I became aware that transients seemed to be
enhanced in a subtle but interesting way, too — probably because of the minimal negative feedback. Electric guitars and
keyboards (miked or DI'd), percussion, drums, voices — everything took on a pleasing, larger­than­life character and
became somehow more satisfying and organic.
Using the Creamer Plus as a mix­bus 'processor' was remarkably beneficial, too, as it introduced a lovely character and
body to DAW mixes — and with so much headroom on the mic input (and a 10KΩ impedance option), you even have the
choice of line or mic input transformers too!
In short, then, I was genuinely impressed with the tonal versatility and musical quality of Sonic Farm's Creamer Plus and, if
you want a high­quality preamp with a flexible character, I can highly recommend it.
