The omission of repeats are most noticeable on historic recordings especially in music from the classical era and this seems disconcerting on the modern ear, as though part of the music has been missed out. I'm thinking of the Haydn string quartet recordings by the Pro Arte Quartet, and some of the movements result in beings ridiculously short - part of the problem was of course the restriction of the 78rpm, and many other recordings have this feature.
On the other hand too many repeats can be a burden - Harnoncourt's set of Haydn's Paris symphonies seemed to have everything repeated and this just sounds overdone - as is some of Britten's Mozart. Sviatoslav Richter said he felt cheated if the obvious repeats weren't observed, and I wholly agree, especially in the Schubert D960.
