This consists of 48 precision resistors per channel (192 total) with 0.1% accuracy and low temperature drift. The result is a sound that feels more \"real\" and less \"processed,\" with rich vocals and dense mids.\u003c\/p\u003e\n\u003cp\u003eNOS \u0026amp; OS Dual Modes\u003c\/p\u003e\n\u003cp\u003eCustomize your sound with a simple toggle:\u003c\/p\u003e\n\u003cul data-path-to-node=\"14\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"14,0,0\"\u003e\u003cb data-path-to-node=\"14,0,0\" data-index-in-node=\"0\"\u003eNOS (Non-Oversampling) Mode:\u003c\/b\u003e Preserves the original sampling rate for a raw, phase-perfect, and highly musical presentation.

It delivers up to 1300mW per channel (at 32Ω) via the 4.4mm balanced output. This provides ample headroom to drive high-impedance headphones like the Sennheiser HD600 or planar magnetic models with authority and deep bass control.\u003c\/p\u003e\n\u003cp\u003eNJW1195A Electronic Volume Control\u003c\/p\u003e\n\u003cp\u003eTo solve the common \"scratchy pot\" and channel imbalance issues of entry-level amps, the K11 R2R uses the audiophile-grade NJW1195A volume control chip.

Questions\u003c\/h2\u003e\n\u003cp\u003eWhat is the difference between K11 (Standard) and K11 R2R?\u003c\/p\u003e\n\u003cp\u003eThe Standard K11 uses a CS43198 chip for a clean, modern, and detailed sound. The K11 R2R uses a resistor array for a warmer, smoother, and more \"analog\" sound. If you prefer vocals and jazz, choose the R2R. If you prefer pop and fast electronic music, the Standard K11 might be better.\u003c\/p\u003e\n\u003cp\u003eDoes it heat up?\u003c\/p\u003e\n\u003cp\u003eR2R circuits involve many resistors handling current, so the unit will run slightly warmer than chip-based DACs. This is normal and within safe operating limits.\u003c\/p\u003e\n\u003cp\u003eCan I use it with PS5?\u003c\/p\u003e\n\u003cp\u003eYes. The K11 R2R supports UAC 1.0 mode, making it fully compatible with PS5 and Switch for an immersive gaming audio experience.\u003c\/p\u003e","brand":"Fiio","offers":[{"title":"Titanium \/ US","offer_id":43683683500125,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ EU","offer_id":43683683532893,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ AU","offer_id":43722964926557,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ UK","offer_id":43722964959325,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Silver \/ US","offer_id":43683683565661,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Silver \/ EU","offer_id":43683683598429,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Silver \/ AU","offer_id":43722964992093,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Silver \/ UK","offer_id":43722965024861,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ US","offer_id":43683683631197,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ EU","offer_id":43683683663965,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ AU","offer_id":43722965057629,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ UK","offer_id":43722965090397,"sku":null,"price":175.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0604\/7422\/8829\/files\/FiioK11R2R-001.webp?v=1758851519","url":"https:\/\/emiuzek.com\/pt\/products\/fiio-k11-r2r","provider":"EMiUZEK","version":"1.0","type":"link"}
