Description

There is a lot of info about Aesthetix. Just click on the website URL. It has the Signature upgrade including Line Stage. Also information here: http://www.aesthetix.net/io.php .

This is the original IO Signature in black. It does not have the shiny new look. But it sounds great.

Original packaging. No smoking environment.

-------------------------------
This is the original Aesthetix IO Signature - when the insides were exceptional and the exterior low-key. What makes this Aesthetix preamp special is:

1. It is the IO Signature model which offers superior performance over the non-Signature model
2. It was sent back to the factory for the line stage upgrade.
3. It has been completely recapped and refurbished.

Two 1/8 inch scratches on top of preamp. Very lightly perceptible - a studied eye can see them only at an unusual angle.

Smoke-free home with electronic dust filters.

The IO Signature is unique in that, the original owner had unit outfitted with a line stage. The line stage includes two extremely well-built volume controls for either phono or non-phono. This means versatility in the variety of sources to pick from.

In addition, the unit has been refurbished with all new capacitors, rendering a performance that is exceptional. When tested with power distribution of a Shunyata Research DPC6 and Shunyata C19 power cord into the wall, superior soundstage took flight, indicating that, in the right system the IO is a keeper.

The tubes are equivalent for the original production model but no special attempt has been made to use special tubes. They work having been replaced when the unit was refurbished and have a light number of hours on them.
--------------------
pre-amp has 16 tubes:
7025 12AX7 Russia Sovtek 10 total
6922 Russia Sovtek 12AX7WT+ 4 total
6SN7 WGTA USA Phillips ECG 2

Power Supply has 8 tubes
6 - 12AX7WT+ Sovtek Russia
2 - Svetlana EL 34 9904 Russia
----------------------

Second owner. Whose been performing with the Aesthetix? current system - Krell KSA 200s, Musical Fidelity NuVista CD player, Wilson Witt II speakers with MIT cables, CocktailX50D music streamer/network server, Project RM 9.1 turntable with Sumiko Celebration MC cartridge. Good company.

Original Packaging.

The Aesthetix Jupiter IO Signature is an upgraded version of the Io Mk II, a no-compromise all-tube phono stage. Its features include:

Zero feedback.
80 dB maximum gain, internally selectable down to 56dB.
Flexible user selectable loading on the back panel from 47Kohms down to 10ohms.
All tube amplification and output (16 tubes total).
Two sets of XLR and two sets of RCA outputs per channel.
Input can be either RCA or XLR.

Part of Aesthetix's Jupiter Range of Components

The Io Signature has a completely separate power supply, using eight tubes, linked to the main audio unit by an umbilical cord. The power supply has two main sections, the heater supply and the high voltage plus and minus supplies. At the heart of the heater supply is its massive, low flux, 210 VA power transformer which has fourteen separate secondary windings that are individually regulated and supply both the power supply and main unit heaters. The high voltage supply is composed of a similar massive 170 VA transformer which feeds a common-mode choke input filtering network and then high current vacuum tube regulators (one EL34/6CA7, three 12AX7 tubes per regulator). Each regulator is capable of supplying 600 volts at 100mA.

A single stereo power supply is standard. This Io Signature was upgraded with two mono power supplies, each with its own mains connection, effectively making the unit fully dual mono.

Another option is a dual mono volume control, allowing the Io Signature to drive a power amplifier directly. With this option, a second set of inputs is included, configurable as either a line-level input (for example, for use with a CD player) or a second phono input. This Io version has been factory upgraded to include a two volume controls, one for each channel.
