So far I have built two amp boards based on a lehmann design and have swapped out most of the capacitors for better quality ones. I have an RCore transformer to keep the noise down and a high end stepping potentiometer. Now one of the final pieces of the puzzle&#8230; I decent a asynchronous USB DAC capable of crazy bitrates. All together I have spent around \u00a3100 on parts and when it is finished I suspect it would go toe to toe with most sub \u00a3500 amps.<br \/>\nI do plan on making something we can sell once I have worked out the bugs but I suspect once I have built the case and stuff they would probably retail for around \u00a3300<\/p>\n<p>I could not wait to plug the DAC in and give it a go to see what all the fuss is about.  We normally use an arcam rPac which was around \u00a3130 and is not a bad DAC from what I have read but as soon as I plugged in the XMOS one I could hear the difference &#8211; much more detail and brighter sound &#8211; I am now super excited about putting it all together<\/p>\n<p><a href=\"http:\/\/www.customcans.co.uk\/blog\/wp-content\/uploads\/2015\/07\/WP_20150709_14_06_02_Pro.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.customcans.co.uk\/blog\/wp-content\/uploads\/2015\/07\/WP_20150709_14_06_02_Pro-1024x577.jpg\" alt=\"asynchronous USB DAC\" width=\"580\" height=\"326\" class=\"alignnone size-large wp-image-912\" srcset=\"https:\/\/customcans.co.uk\/blog\/wp-content\/uploads\/2015\/07\/WP_20150709_14_06_02_Pro-1024x577.jpg 1024w, https:\/\/customcans.co.uk\/blog\/wp-content\/uploads\/2015\/07\/WP_20150709_14_06_02_Pro-300x169.jpg 300w\" sizes=\"auto, (max-width: 580px) 100vw, 580px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I am slowly building a high end headphone amp from bits and bobs I can pick up on line.
