Change my AA front-end


I'm suspecting my AA digital gear may not be providing ALL the bass energy possible IMS. My buddie has the same Sonatina speakers and even on 6" granite platforms has better bass response. Of course, his room is smaller, but I believe his Theta transport and EVS dac are just that much better in the bottom-end. My gear> AA dds.pro transport / dtipro.32 (ad.3 ditter) jitter filter / ddev3.0 dac with Dusty Vawter's mod and Perpetual Technology op-amp upgrade / M.P.S. dedicated power supply for dde-dti. I'm using Audio Magic i2s mystic reference silver throughout. BMI Whale Elite power cords on dds.pro & M.P.S.

Not having sampled any other CDPs lately I'm interested in recommendations for a CDP (new or used) that would improve apon the AA gear and be purchased for what the AA could be sold for. I don't want to get into seperates or put anything into the upgrade. SACD is not an important consideration. I'm using a Moth s45 SET integrated amp with the Sonatinas and Shunyata Hydra PLC. The only areas I want to improve are bass weight and overall fullness to the presentation. I'm also looking into adding a tube preamp down the road. Thanks.

I have no idea what an AA is. Therefore, I will just say that if you are considering a new cd player, I would highly recommend the Sony SCD-1 SACD/cd player. It is everything the reviewers have said it is. Strong bass, articulate, smooth and yet very detailed highs, excellent decay, etc., and a refined synergy of the music as a whole.

I had owned and still own a Sony DVP s9000es dvd/SACD/cd 2-channel unit. The s9000es is a very nice all around unit. Certainly not the best sonically but it will get you about 7 or 8/10's of the way there.

The SCD-1 is simply better in every sonic category and may get you perhaps 9/10's or more of the way there.

-IMO
AA refers to the defunct Audio Alchemy. Isn't the SCD-1 Sonys top-of-the-line player? Like I said I wasn't looking for the best, just something better than my AA gear which is about 6 years old technology-wise. Thanks for taking the time.
personally, i don't think the front end is your problem. i had the same front end driving a power amp direct with exactly the same problem. once i put an audible illusions tubed preamp in, all the fullness and bass suddenly appeared. i'd tend to blame it on the passive attenuator in your moth. hope this helps, harry
