Do both for best sound get NOS Amperex not cheap but the best sound.
Which one produces a bigger change... changing a rectifier tube or tubes on my DAC?
Trying to see which tube upgrade to do first on my Modwright Oppo UDP205. Tubes on the DAC or rectifier tube? At the moment Im using Sylvania on DAC and a 5R4-GY on rectifier from Andy at Vintage Tube. Any recommendations would be great. Thanks.
