For me, it's important to be able to: - Monitor the input level to ensure you aren't clipping the ADC - Be able to set the input sensitivity to best use the dynamic range of the ADC and match levels with other sources - Be able to EQ the phono to my liking. The options include each of the digital inputs, as you'd expect, but adds to that list the external clock input and an internal generator, the sample rate of which is established with the final rotary control, from any of the standard rates between This is an unusual arrangement and should be used with considerable care, as inappropriate settings will badly damage the audio signal.
The idea behind the facility is to enable the B2 DAC to serve as the master clock, by setting it to run on its internal clock. The rear-panel word-clock outputs can be used to distribute this master clock to all other digital devices in the system eg.
In this configuration, the digital output from the slaved device should be synchronous with the DAC's internal clock and high-quality conversion will result. The advantage of this is that the DAC's converter chip is running on its own internal — and very stable — crystal clock, rather than trying to slave to an external or embedded clock, and as a result, jitter artifacts should be considerably reduced and the audio quality enhanced. Several commercial DACs employ techniques for running the converter from a stable internal clock divorced from the source's embedded clock, but very few do so by acting as the system master clock, even though this is actually a very logical and practical solution.
The down side is the potential for user error, which is quite a serious risk. However, the source audio will be corrupted with regular clicks as the two clocks drift in and out of sync, and the audibility and rate of those clicks will depend on the nature of the audio material and the relative drift of the clocks. Unfortunately, there's no warning for this simple user error: no flashing lights warn of clock drift, and there's no automatic muting for mismatched clocks. The best case is when the internal and source clocks are mismatched say When the clocking arrangements are configured correctly, performance is very good indeed, achieving an AES17 dynamic range figure of My overriding impression of the Bomber converters is that they really do sound a lot more 'analogue' than most.
The closest-sounding alternative converter to the Bomber that I can think of is the lovely Universal Audio , which I reviewed recently in SOS and which has a very similar audio character. I wasn't surprised to learn, therefore, that Rich Williams, the man behind Burl, also designed the UA and describes his B2 converters, logically enough, as the 'next generation' of converter.
During the course of this review, Hugh used the Audio Precision Analyser to take some test measurements of the B2 converters. The Burl B2 Bomber converters are designed to sound musical above all else, and have a distinctly analogue character to them that colours the sound, but in a generally beneficial way for many applications. Mixes seem to glue together very well through these converters, and sound smoother, deeper and wider than any budget converter can manage.
The D-A unit is slightly let down by the unusual clocking options, but the risks are easily mitigated. What is Binary? What are Opamps? What are Opamps and Comparators?
