Most are disappointed because they think, and are told that equipment, better, is where pro sounding recordings come from, and they never learn that 75 percent of the great sound is the room, the recording space. Many check out with never learning this, the ones who stay long enough eventually figure it out. The room is the big secret. You must have bass frequency control or you won't get pro sounding recordings. You must control flutter echo and comb filtering, or your recordings are left to hope for rare luck that you might be in a spot in a room where all things happen great just by chance.
If you have a good room, then you can learn to get semi pro recording fairly quickly. Good equipment and engineering are icing on the cake and they make you one of the big boys, but having a proper sounding room is most of the battle. If you don't have one, you will surely never be really satisfied.
