Onkyo t-4030

Comment: This tuner was taken solely for the sake of SPDIF digital output, so that the subsequent conversion of a digit into an analog occurred in the quality path of the external DAC. That is, the tuner in this configuration is used exclusively as a digital device. And in this mode, the quality of its digital output completely satisfied me. No failures or no folding in sound. It plays much easier from analog outputs, the scene is already, moreover, the shortage of the lowest bass starts immediately and there is no such transparency on HF as through an external DAC. This is understandable, since the internal DAC in the tuner is quite simple. The sensitivity of the special revelations did not happen. Sensitivity is good, but it is just as susceptible to interference as other receivers and phones that I have at my disposal. That is, without an external antenna or windows facing the radio tower, there is little that will be able to listen to quality.
I recommend this tuner exclusively to those who have an external DAC decent level. Otherwise, it is worthwhile to look at the tuners built using the classic analog circuitry - they will have higher quality analog signal without unnecessary transformations of the FM “figure” analog.

Comment: Question: I got this tuner today. Honestly, we expected more. The reception quality of most stations is very bad: ((solid background and crackling) Our radio 104.0 does not catch at all. I have not found one. Can you advise something to improve reception?
Answer: It is likely that the signal of some radio stations is very weak at the installation point of the tuner .. The link that strongly influences the quality of the reception of the tuner is the receiving antenna. If the antenna is located in the place of the strongest radio signal, the reception quality will be maximum. Experiment with the location of the antenna by moving it in space.

Comment: Question: Does this tuner have chio, digital circuitry on analog FM or just an ADC is added to the output?
Answer: Unfortunately, the manufacturer does not provide detailed information on this issue. Most likely the analogue signal of the FM tuner is fed to the RCA outputs. To output the signal from DAB radio stations, the sound is fed to the digital output.
