Apologies for a stupid question - I'm mainly an analogue listener.
I've recorded some of my LPs onto a 24bit 92khz audio recorder in the PCM WAV format and was wondering if the playback would be improved if played on something else rather than the Mac laptop.
I don't have a digital out on my audio recorder.

I'd output from the laptop via USB to an external DAC that should give you 100%.

Thanks. How much would a DAC better than the Macbook built-in one cost? Which one would you recommend for a noticeable improvement?

Get one of the Topping or SMSL DACs for about £100 they are decent for the money.

It's not so much that it will be a better DAC just that having it off board eliminates the possibility of added noise.

Like Lawrence says a DAC from Topping or SMSL will be notionally perfect and not expensive.

A separate DAC used with a MacBook is noticeably better but you don't have to spend too much cash. I have had a number of MacBooks and use Audirvana and my off board DACs have always sounded better.

S.M.S.L SU-1 has had many positive reviews and is a very sensible cost

is it possible to sum up a can of worms? :D

What does PCM mean? Used to have a Marantz PCM player, sold it for £70 on ebay, even though it was fuct.

Pulse Code Modulation. All CDs are encoded in PCM. DSD/SACD is different, it's been described as "PDM" although there is some argument around that.

It's basically the way the analogue waveform is reconstructed from the bits (pulses) in the datastream. Think the classic picture of a bar chart approximating a sine wave - the more bits the bigger the bar.

The analogue signal has just three properties - frequency, amplitude and phase - the sampling frequency determines the highest frequency that can be encoded, bit depth determines the maximum amplitude that can be encoded.

Thank you fellas.
