QHW Audio - The Vinyl
The Vinyl is a high quality phono preamplifier wich features an active
and discrete RIAA stage and is suitable for MC and MM cartridges.
Input impedance for MC and capacitance for MM is selectable by user,
along with MC gain. Even has a position for high input impedance for MC
cartridges which is useful with some fancy MM low level cartridges,
like low level Grado's, whose need the gain of an MC but with a high
input impedance. Many preamps don't cover this scenario. A set of
features and sound quality that is hard (if not impossible) to find at
this price level or even in some devices costing some times more.

Vinyl achieves very good calification for its sound. It brings rythm
and dynamic to records and an excellent spreading and neatness to high
frequencies. Listening to it is addictive and we enjoyed revising both

the QHW The Vinyl and the Gold Note PH-10 are a big step up from entry
level products and neither disappoint. Both remained in the reference
system while judging cartridges and loudspeakers, without reservation.

Vinyl will meet the need of many music lovers, even for extended
listening sessions without undue fatigue, with ease of use, flexibility,
and quiet quality service. I've enjoyed my time with this product, even
though it has sat quietly and unassuming, just doing it's job really
well. Of course, great records sound great, yet even some I played
reluctantly were far from disappointing. A strong contender for a
Discrete components design
The Vinyls is based on QHWAudio’s AE2270 amplifier we featured in The
Box. Is a whole discrete small signal amplifier with high output current
capacity and very low distortion.
The Vinyl features two units
of AE2270 per channel: one for RIAA curve amplification and one for an
aditional gain stage at the output that brings same benefits that an
unit of The Box would do. Therefore, RIAA amplification is totally
discrete and, as we can’t conceive in other way, although there are
another thoughts regarding to this, using an active network.
input stage, for moving coil cartridges, uses a discreet frontend, with
BJT (Bipolar Juntion Transistor), since they are the ones that offer the
lowest noise with low impedance sources, combined with integrated
electronics, also bipolar, in a way that we can get a low noise and low
distortion MC stage without compromising cost and offering an affordable
Adjustable MC cartridge impedance and gain
Impedance “seen” by the MC cartridge at the phono preamplifier input,
also known as load, is very important for an adequate frequency
response. Theorically, ideal input impedance may be equal to cartridge
coil impedance but, actually, things depends of personal taste. The
Vinyl allows to choose between six impedance values that will provide an
adjust for most (if not all) cartridges in market. Even it has a high
impedance posiotion specifically thought for low level MM cartridges,
whose need the MC preamplifier gain amount and a high load and they have
trouble with many MC preamplifiers.
The Vinyls also features two
gain levels (64 dB and 71 dB) to make it compatible even with
cartridges with extremely low output level.
Adjustable MM cartridge capacitance
Same way that happens with MC cartridges and impedance, MM cartridges
capacitance, also known as load in this case, is very important for
frequency response. The Vinyl allows you to combine five basic values of
capacitance, whose go adding, to find that what fits better your needs
and personal taste.
The Vinyl is designed and handcrafted in Spain.
