BetolMaybe you misunderstand. All FM transmitters are analogue by their very nature - they all transmit a frequency modulated analogue signal - but the source material (whether it is vinyl or CD) is first digitised by a 13 bit encoder before being sent to the transmitter and then decoded back into analogue for transmission. This is done to prevent losses if the transmitter is some distance away and not in perfect line-of-sight.
So the so called purity of FM includes two stages of digital conversion. Whatever is the reason for FM sounding better, it's not the method of transmission. My guess is it's limited HF bandwidth of FM and sharp birdie tone filtering at the treble end which limits the audibility of the digital arifacts you can hear so clearly on DAB.

Hi Gopher,
thanks for update me.
I'm looking for good, for the money, tuner to continue to hear some radio station that I like it.
I'm thinkin on some Sansui analogue (don't remeber wich model), there are also some digi/analog (TU-S5) and some digital (T-9) that are on my budget to this (US$100 or below). The key is to get hear, of course to avoid very huge shipping cost.
Best regards,
Beto
P.S. there is also a didital NAD (402) from '90's and an analog Telefunken (CT-1)
I'd suggest the one I have - a Denon TU-260L Mark 2. They are a few years old now but got excellent reviews at the time and sound great in my opinion. Sometimes however they can sound too good and show up the poor sound quality on some of the heavily compressed commercial stations over here. They can be had in discount stores in the UK for around £70 (around $120).They can also be heavily modified to make the sound even better.
Hi Gopher,
thanks for your advise, but I'm affraid that this model never have sold here because I can't get any info on the local pages.
I believe will be very cheap on some ebay auctions (35 pounds)but I'm trying to find here some one because I will like to avoid huge shipping cost.
Here are some Sansui, Marantz, Telefunken, etc, vintage tuners and some from Technics, Yamaha, Kenwood,NAD, etc from the 90's.
Kind regards,
Beto
