my upstairs hifi has in the last few days turned into tweeky crazyness
i have a beresford tc-7520 on its way and after reading that these LM4562 thingys are in many peoples words a 'no brainer' i now have a pair of them wraped in a little bit of plastic.
im not going to put them in straight away i want to get to know the dac before i decide to upgrade it.
and this is why im getting ahead of my self, i recently bought a firestone tubehead pre-amp. i got it cheepy cheepy whilst looking for something to esentially just add an input to my tripath.
when i first got it i plugged it in and didnt like, it left it to burn in for a bit with no real joy. i decided to sell it but in the mean while i plugged it into another system just for the hell of it really. it sounded ok but was no major improvement. but, it obviously gave it more of a run in as when i just plugged it back into the tripath today it sounded a lot better than before and def seemed to add something.
the bass is still the major week point of the system though. there is just not a lot of it and its rather ill defined
i have read that these firestone things are a tweakers paradise and after opening the top on it today a can see there are 2 pairs of switches. 1 that change gain and one that change how the volume control works. fun fun fun fun ... no change to bass on the different settings though
first question: are these switches in pairs because there are 2 channels
second question: the other thing i notice are a pair of opamps (i think) one has
0720
jrc5021g
printed on it, the other has nothing on it.
can i upgrade these to something that might improve the bass
i guess i wont do anything until the beresford has burned in and i can hear what benefits that brings. but like i said im getting ahead of my self.
i think i have just opened a can of hifi tweeking that my non techy mind can fathom and i want to know more more more
