The \"70\" in the model name denotes this specific element, highlighting its importance in the amplifier design.<\/p>\n<p>The model continues the unique design philosophy of Erik Andersson, known for his previous audio creations. This model carries on the legacy with the integration of Swedish Lundahl interconnect transformers, improving sound quality by better preserving signal integrity and minimising losses. The amplifier's circuit design has been carefully refined with a focus on component selection, layout optimisation and precise routing and bias points for the tubes. This design eliminates external feedback and adopts an \"air-wired\" method in the signal section to preserve the purity of sound.<\/p>\n<\/p><\/div>\n<div style=\"flex: 1;\">\n        <!-- Video p\u00e5 svenska (standard) --><br \/>\n        <iframe loading=\"lazy\" width=\"100%\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/VPNcMjhtehk\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p>        <!-- Klickbara l\u00e4nkar f\u00f6r andra spr\u00e5kversioner --><\/p>\n<div style=\"margin-top: 10px;\">\n            <a href=\"https:\/\/www.youtube.com\/watch?v=JPy_Un2GVxY\" target=\"_blank\" style=\"margin-right: 20px;\" rel=\"noopener\">Video with French subtitles<\/a><br \/>\n            <a href=\"https:\/\/www.youtube.com\/watch?v=_2FP1bwjcm8\" target=\"_blank\" style=\"margin-right: 20px;\" rel=\"noopener\">Video with English subtitles<\/a><br \/>\n            <a href=\"https:\/\/www.youtube.com\/watch?v=eNe7YYlpX4c\" target=\"_blank\" rel=\"noopener\">Video with German subtitles<\/a>\n        <\/div>\n<\/p><\/div>\n<\/div>\n<p>The power supply in the amplifier is passively regulated, a decision that came from extensive listening tests that showed this method to be superior in reproducing both dynamic range and micro details of the music. This passive control is in line with the topology of single-ended Class-A amplifiers, traditionally celebrated for their ability to deliver a magical listening experience, where the robust power of the GM70 tube plays a central role.<\/p>\n<p>Challenging the norms of industrial design, the chassis of the Erik Signature 70 has a wider than deep shape, facilitating integration into home environments while maintaining an aesthetically pleasing appearance. The basic design of Andersson's previous models is preserved, with a two-level layout that strategically places the power supply above the signal section to shield it from interference.<\/p>\n<p>Knispel Audio places great emphasis on the visual appeal of its products, arguing that high-quality audio equipment should please the eye as much as the ear. Therefore, considerable effort has been put into the aesthetics of the Erik Signature 70, such as the elimination of visible screws both on the amplifier and its remote control, and the presentation of more than 20 design sketches before the final design was determined. The attention to detail extends to the use of 1.5 mm thick brass for the top of the amplifier, which is carefully cut out, polished to a mirror-like finish and then chrome-plated. The side panels offer customisation options with solid stained khaya mahogany or walnut, treated with hardwax oil for durability and beauty. A brushed aluminium option that is naturally anodised is available for those who prefer a more discreet appearance.<\/p>\n<p>This uncompromising approach to both performance and aesthetics ensures that the Erik Signature 70 is not only a centrepiece of any sound system, but also of the living room in which it is located.<\/p>\n<p><strong>GM70 tubes<\/strong> are naturally chosen for their magical ability to reproduce music in harmony with their power. I think of the tube world as a balance scale; more nuance requires tubes with less power - more power requires tubes with less nuance. With this amplifier design, this is not true. Here you get 2 x 25W into 8 ohms that are literally bursting with musical life. It is absolutely amazing! This direct-heated tube is also well-built, has consistent quality and good durability \/ longevity. It is also still relatively good on NOS tubes. And not least, it has a very high sound quality with high output power.<\/p>","protected":false},"excerpt":{"rendered":"<h4>A masterpiece!<\/h4>\n<p>A true dream amplifier! The culmination of the life's work of legend Erik Andersson.<br \/>\nA musical dream design based on the GM70 tube.  All impedance matched with interstage transformers. With its 2 x 25W into 8\u03a9, it drives most anything. And it drives it with a breathtaking richness of nuance, colour and musical drive.<br \/>\nPerfect not least for those who have the acoustic models of reality as a yardstick. The transient richness in both large and small is breathtaking!<br \/>\nThe amplifier comes with NOS tubes. And Knispel Audio has chosen the graphite version of GM70 as these are considered to sound better in this construction and also be more durable.
