Anteaker , I’m so sorry you had to go through such difficult surgery before you decided to convince yourself to build some equipment. Best wishes for a speedy and complete recovery. I’m sure you will be very happy with you choice to use GR research. Great first choice , I doubt you could find anyone better than Danny and GR to get you started. Amazing talent and superb sound and value for the money . I pray you won’t need another operation to get you to decide to build an amp to go along with those GR speakers ! I hope you have a great time building !
