Difference in sound between Siemens e88cc and e188cc?
HI, Mainly more energy in upper regions.Something else is the ECC88 having more energy on top, lighter bass, even some have better mids compared to their bigger cousins, but are more prone to noise have more hiss and you have to check they can wit... 
My record player sounds slightly high pitched
