I have a DAW with 3.4 Intel, 2 Gig RAM and 320 gig in hard drive space. I use Delta 1010 and Audiophile 24/192 cards. For some reason, the quality of recording on Audiophile 24/192 (not 24/96 card which came out initially) sounds better than on Delta 1010. I record keyboards and vocals mostly and rarely Guitar and I was comparing the quality of vocal parts. Moreover, I had used KSM44 on Delta 1010 and I was using a cheap $100 Senheizer on Audiophile. Since I am planning to upgrade my studio, I was wondering if I should go for high end AD/DA converters, Avalon preamps etc. or just stick with my current sound cards (or may be get Presonus Firepod or Echo Layla 3G) and get Avalon pres. Also, I had seen one of my friends use a Mackie 1402 vlz in his studio and he had a cheap 250 dollar PC (may be Pentium 3 or something) and a SM58 and still his recordings sounded amazing. (He did mostly keyboards and vocals too). I'm so attracted to that mixer since that time. I'm just worried that I might spend money on upgrading my studio and get no upgrade in quality of recordings. There's just too much out there and a lot of it is not required !!
