RCA Soria Series 3 LP Set with a 30 page 12" x 12" book
As with everything I have heard from the Soria Series the sound is first rate.
Unfortunately this set is from the age of record changers so the discs are Sides 1/6, 2/5 and 3/4 requiring a lot of record switching instead of just flipping over. But is is a small price to pay for the excellent music and sound they contain.
