If all you want for Christmas is one of the world's best phono stages for less than half the retail price, for sale is the latest and current ASR Basis Exclusive HV Phono
Preamplifier. Is this the greatest SS phono stage ever made? It might be but if not it is surely among the very elite phono stages ever produced. The ASR line is the brainchild of its singular owner Friedrich
Schaeffer who has been building novel and superlative audio gear since 1980.
The ASR Basis Exclusive phono stage was first brought to world prominence by
Harry Pearson many years ago as one of the finest phono stages on the planet.
It has gone through several prominent iterations; most notably in the 90’s,
2006 and 2013. The current and newest version is a special high voltage (HV) power supply
modification that was introduced in 2019. This is the known as the ASR Basis
Exclusive HV. The unit for sale was purchased in March 2019 and I am the original owner. It is perfect. I have owned every version of this remarkable phono stage and the latest is
absolutely the best and a significant improvement from all previous
versions particularly in power delivery, dynamics, sound-staging and bass performance where it is on par with anything ever made.
The keys to ASR’s technology are several, but common to many
of Friedrich’s products are the powerful battery supply of the front end of his
devices. The power supply is massive, and the advantage is that of decreased
noise and interference from the AC line which allows for a purity of sound that
is difficult if not impossible to find elsewhere.
There’s a wealth of material on the web site, including the
owner’s manual, company history and other information. (Check the tabs in the footer also.)

High End Phono Preamplifier ASR Basic Exclusive
Some pertinent details are below.
End Phono Preamplifier ASR Basic Exclusive
ASR Basis Exclusive is one of the most elaborate phono preamplifiers on the
market and surpasses so many power amplifiers.
total sieving capacity of 1,300,000 uF and an external battery charger ensure
an extremely stable and clean power supply.
Basis Exclusive, in addition to the usual asymmetric Cynch sockets, equipped
with balanced XLR inputs, because pickups are symmetrical sources from the
working principle. At the ASR Basis Exclusive you can operate it
output is also equipped with Cynch and balanced XLR connectors. The two
inputs have two separate input stages and are independently adjustable. A
signal-controlled automatic switches the main unit to battery mode.
ASR Basis Exclusive is also equipped as standard with high-speed operational
amplifiers. Thus, the Basis Exclusive receives a previously barely heard
bass foundation, a precise resolution of all finest information, with a
particularly stable spatial image.
Noise-to-noise ratio: MC better than 68 dB, setting dependent.
Frequency response: - 3 dB from 3 Hz to 200,000 Hz
Accuracy of RIAA equalization better than 0.5 dB from 20-20,000
Distortion: from 5 mV to 5 V AC at 100 R at 1 kHz <0.001, from
20- 20,000 Hz <0.005%
Input resistance: phono MM and MC 5 ohms to 47 K ohms
Input capacity: between 100 pF and 320 pF

Although I have had many state of the art audio products
over a lengthy career as an audiophile, I have often said the greatest piece of
gear I have ever owned is the ASR phono stage.
To begin, its sound is simply stunning. I have yet to hear a better SS
phono stage and that includes many that retail for 5X (or higher!) than the cost
of the ASR. Second, it is stunningly beautiful. The illumination of the
interior LEDs through the dark plexiglass front panels are a not only functional
(they indicate operating conditions are also diagnostic if the unit ever needs
service (it won’t!), but they are also drop dead gorgeous to behold. Friedrich
doesn’t make gear like anyone else. His pieces are truly inspired and are as
much expressions of industrial design art as they are sonic masterpieces.
Functionally, the unit can accept 2 phono inputs in either
single or balanced mode, and has both single and balanced outputs. Friedrich
strongly recommends using balanced inputs (even with RCAs) as MC cartridges are
inherently a balanced devices, but it is not necessary to use balanced outputs
to achieve this benefit. The unit is configured for load, capacitance and balanced/single
ended in and out through internal dip switches as explained in a thorough and
well diagrammed instruction manual. The batteries are user replaceable with readily
available Panasonic 12V units. This needs to be done every 3-5 years or so
depending on use. The audio control unit and the power supply are connected by a massive umbilical. The unit comes with an ASR Magic Power cord as standard.
I am going to be extremely sad to part with this piece, but
down-sizing mandates it. I can only hope that the unit winds up in a home deserving
of its exquisite performance and pride of ownership. As far as I know, this is the first listing for the HV Basis Exclusive Phono that I have seen for sale. I expect it will go very quickly. Please forgive the reflections from the iPhone photos but the unit is cosmetically and functionally perfect (check my feedback, buy with confidence). I will accept personal check or cashier’s
check and welcome local pick-up. If you can buy a better phono stage at twice the price- buy it! Paypal adds 3%.
