7ES-3's strength IMO are smaller ensembles and voice, not large orchestral or rock music (I have found those who listen to mostly pop/rock prefer other brands of speakers). I have owned three different models of Harbeths and presently power my 7's with a LFD NCSE, but have had tube amps, line/power, and other integrated's (including Pass and Moon). If you find a used LFD Zero Mk III LE (even better with phono stage) to pair with the 7's (and you can live without a remote) I believe you'll be quite surprised at how good that combination is, and you can put the money you save into more (LP's/SACD/Redbook) source material.
