Two different output stages can be selected – either an electronically balanced stage, or a discrete transformer-balanced class-A stage sporting a heavy Carnhill output transformer. Vintage Class A mode produces a fat and punchy sound with mid-range character and a warm top end, while the electronically balanced output stage is less colored and perfect for clean amplification.  A sweepable HPF from 30Hz to 400Hz allows precision crafting of the low end.\u003c\/p\u003e\r\n\r\n\u003cp\u003e\u003cem\u003e“SP501 offers a unique, diverse set of flavors at an amazing price,”\u003c\/em\u003e states TK Audio president Thomas Kristiansson, \u003cem\u003e“We couldn’t be happier with the final product.”\u003c\/em\u003e\u003c\/p\u003e","brand":"TK Audio","offers":[{"title":"Default Title","offer_id":44450121646183,"sku":"79768","price":839.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/tk-sp501_79768_1_434438d4-3181-43fe-b98a-4197f7efb922.jpg?v=1787091783","url":"https:\/\/vintageking.mom\/products\/tk-audio-sp501","provider":"Vintage King","version":"1.0","type":"link"}
