The Signature Two is an audiophile moving coil phonostage employing low-noise discrete transistor circuitry throughout - no op-amps or transformers - and offers variable gain and cartridge load impedance.

The Signature Two's circuit is the culmination of over 25 years experience in the design and production of audiophile phonostages and is a four-stage design using discrete transistors operating in Class A. The first stage is a low-noise design with adjustable load impedance from 32 ohms to 1100 ohms and gain variable from 52dB to 72dB, load and gain being adjustable independently of each other. This allows a very wide range of low output moving coil cartridges to be handled with optimum performance.

A proprietory discrete transistor regulator provides extremely clean power to this first stage to allow the circuit to perform at its best regardless of the quality of the mains electricty supply. The second stage precedes the highly accurate passive RIAA network comprised of low-distortion polypropylene capacitors and audiophile MELF resistors. The third stage is another gain stage before the final stage buffers the output for a low output impedance.

The on-board power supply is a linear design employing a torroidal transformer, generous-sized capacitors and another proprietory discrete transistor voltage regulator with very low noise. The supply to the all-important first audio stage is further regulated to provide the it with the correct voltage with extremely low noise and ripple - lower than possible with the common off-the-shelf monolithic alternatives. Each stage also has its own local decapitors with carefully routed earth tracks to eliminate ground current interactions with audio grounds resulting in a gloriously clean performance which reveals all the recorded detail with breath-taking realism.

As with all Rothwell products the Signature Two is designed and built entirely in the UK.

Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as DPD or UPS. 

INTERNATIONAL ORDERS: We offer competitive rates which can be confirmed by email. Please just ask – we will need a full delivery address and telephone number. Smaller items are delivered using Royal Mail Small Packets Airmail with International Tracked and/or Signed depending on value of item and availability of the service. Larger International shipments are sent by insured and tracked services using UPS. If there are any delays due to specific customs regulations, etc, you will be contacted by Turntableworld or by the courier with a request for any further information required. Customs duties can apply for shipments to any countries outside of the UK depending on where the product you have bought is made. Customers are responsible for all taxes and duties incurred when the items enter their country.

COLLECT IN STORE OR HOME INSTALL:At the request of the manufacturer some items cannot be supplied by mail order but you can click and buy them and then elect to collect them from our store or arrange a home install (if applicable). Applicable items clearly state that they are Collect in store or home install. Once ordered you will receive a message prompting you to contact us by phone or email to arrange for us to deliver and install or to reserve and collect from our store at your convenience, you will also be advised of the delivery time / stock availability as not all Home install / collect in store items are held in stock.
