Ok I linked the turntable's rca to the receiver's Phono input, I found that the gain dial on the turntable was set to the max (+) so I turned it down to the lowest (-) (should I set it back to high?), using the first receiver's tape monitor's outputs (rec) I linked it to the SB1240 line in connection, and I will need to buy a new RCA Male to Male wire and link the SB1240 to my receiver's Tape Monitor's input (play) in order for the labtop (using Foobar2000 for CD Playing and online streaming such as Sirius and similar) to access the speakers connected to the receiver.
I discovered that the speakers were a part of my mother's old Audiovox DVD Home theater 5.1 player.
Using "Spin It Again" and it's "Level Wizard" I found that the record player isn't as load as it was before as I can hear sound but it doesn't get near the level threshold anymore. I assume that means that using the turntable must have some sort of amplifier linked to it's USB and whatever DAC it used. Now that the computer is using the SB1240 USB and other differences in the connection from the Turntable's RCA to the Labtop there isn't any amplification in the sound. The sound however does sound better and less noise.
This leads me to consider the following for my mother:
#1 First update the speakers to one of the recommended speakers above. For the current setup should my mother get a better budget Turntable which of the above recommended speakers would not cause any bottleneck (just want to find out if I can afford now or how much I must money I should start to save up for my mother).
#2 I'm considering also getting at the same time or shortly after the speakers a amplifier or preamp (have to learn the difference on what they do to know which if not both would help my mother), or whatever for my mother to help heighten the volume of the turntable to help maximize my mother's sound for her digitization recordings.
#3 After the first two then the weakest part of her setup I guess would then be my mother's turntable itself thus upgrade that to one of the above recommended turntables for her.
#4 Finally should I get my mother a $200 or above CD Player, upgrade the DAC, get a better software then Foobar2000 (such as from what I read a software called JPlay or perhaps another software), or an better disk reader for the labtop. Maybe for the labtop all three (better DAC, software, and disk reader). She has alot of records and TONS of CDs (but currently no Super Audio CDs (SACD) ) in her home.
Thank you everybody for your current inputs and every future inputs will be welcomed.
