Full complement of Mullards arrived today. Difference was immeadiate. Mids and highs blend beautifully. Very smooth yet still well defined. Extremely musical.Of course they are not broken in yet I've played a variety of music. Orchestral classical, great. Bill Evas at the Village Vanguard, piano, bass and drums all gorgeous.
Foo Fighters Sonic Highways on the table now, terrific. Even listened to an hour of iTunes. Noticeable improvement.
Thank you all. Will post again after some break in time.
