Overview<\/h4>\n

The MRE 120<\/strong> received critical praise upon its introduction and for the 10 years it was in production. In 2004, it was replaced by the MRE 130<\/strong> after a decade of experience and further development of the core MRE 120<\/strong> design. The MRE 130<\/strong> made improvements in detail retrieval and stability through refinements in its circuitry, most critically, in the output stage. Nearly another decade later, a major overhaul of the MRE<\/strong> series was undertaken based on the newly-developed KT 120 power tube. The KT 120 enabled greater power reserves and an even wider bandwidth in the MRE<\/strong> power amplifier output stage. Extended listening tests with a newly-developed output transformer and power supply led to the release of the MRE 220<\/strong> in 2013. Its special virtues resulted in a unique combination of extremely high reliability with the utmost level of sonic finesse. The MRE 220<\/strong> served as the optimal power amplifier for an unusually wide range of loudspeaker combinations. Whether employed in a bi-amp configuration with horn systems, or simply mated directly to a wide variety of high-end loudspeakers available in the global market, the MRE 220<\/strong> remains a rock solid reference. Now, yet another 10 years later, Octave<\/strong> has taken the MRE<\/strong> series to another level: introducing the MRE 220 SE<\/strong>.<\/p>\n

Today\u2019s modern loudspeaker designs feature high-resolution and fidelity beyond what was achieved in the past. This, combined with the triumph of high-resolution digital formats and an extraordinary leap in vinyl playback fidelity, has led to an unprecedented quality of music playback in modern high-end systems. Despite all efforts, developing a power amplifier that harmonizes perfectly with all loudspeakers is \u2013 as experience shows \u2013 still very difficult, if nearly impossible. The requirements of the loudspeaker are too different in terms of power requirements, bandwidth and its performance, which is affected by the damping factor (and\/or negative feedback) of the power amplifier.<\/p>\n

In listening tests with many different loudspeakers during the MRE 220 SE<\/strong> design process, an important new tool emerged that ensures more optimal matching between our amplifier and a wider range of loudspeaker designs: an option to vary negative feedback that impacts the attenuation factor. Through use of chassis-mounted switches, the listener can choose between two damping factor settings, \u201cLOW\u201d or \u201cHIGH\u201d, along with separate settings for negative feedback. This is a completely new approach to the problem of a tube power amplifier that has to cope as well as possible with all the loudspeakers available on the market. With this unique adjustment option, the interaction of the MRE 220 SE<\/strong> with nearly any loudspeaker can be optimized almost perfectly. The result of this flexibility speaks for itself: an incredibly clear, spacious soundstage with a perfectly resolved and entrancing midrange that is free of any impurities, along with a silky, beautiful tonal balance.<\/p>\n

After eleven years, and after extensive technical development projects at Octave<\/strong>, it was time to further adapt the MRE 220<\/strong> mono power amplifiers \u2013 the rock in the surf \u2013 to the higher demands of modern loudspeakers. Long listening sessions led to the solution of an adjustable damping factor. The new MRE 220 SE<\/strong> damping factor can now be flexibly adjusted to ideally suit the respective speaker \u2013 resulting in rock solid reproduction quality with virtually any loudspeaker.<\/p>\n<\/div>\n","protected":false},"featured_media":59855,"template":"","meta":{"_acf_changed":false},"product_brand":[929],"product_cat":[315],"product_tag":[],"class_list":{"0":"post-59852","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-octave","7":"product_cat-power-amplifiers","9":"first","10":"instock","11":"taxable","12":"shipping-taxable","13":"purchasable","14":"product-type-variable"},"acf":[],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product\/59852","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":0,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product\/59852\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/media\/59855"}],"wp:attachment":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/media?parent=59852"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product_brand?post=59852"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product_cat?post=59852"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product_tag?post=59852"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
