Right up this alley is most of Ike Quebec's old Blue Note catalog. Check out "Blue & Sentimental" or "Heavy Soul" Both are great, clean sounding recordings. Though older, they both sound as if they were recorded yesterday. Something more current would be Houston Person's, "Just Between Friends", a duo with Ron Carter, with a big slow sound, exquisitely recorded. Something different to listen to is Joe Henderson's "State of the Tenor" with bassist Ron Carter and drummer Al Foster. I prefer vol 2, but the 2 disc CD set has both volumes. Have a listen to the cut "Soulville". I also can add a vote for Celtic66's suggestions of I. Jacquet and B. Webster. Again, though older recordings, they typically sound great and both have that big slow sound you describe.
