As several have mentioned you need to stick with something specifically designed to reproduce the old analog sound, such as Tvad suggests. Analog has advantages in many areas such as "soft clipping" on tape etc. Many older generation audio professionals prefer analog for certain applications because of how it modifies the sound in a desirable way - for example analog is very good at compression (reducing dynamics) with less risk of sounding bad. Many people prefer that old analog tape sound as opposed to the unforgiving digital sound.
I think it is hard to deliberately replicate this sound using a device that takes CD digital and modifies it (after all, the analog sound is part of an entire studio and manufacturing process).
Doug Sax (of Sheffield labs fame) still uses his brother's designed tube amp circuitry to help create CD masters that have some compression, warmer vocals and a bass kick drum punch. If you buy Doug Sax Mastered CD's then you may find them a just bit closer to old analog sound than others...just two cents.
