was measured into 4ohm and 10ohm loads, from 100Hz to 780kHz, to show the interaction of the LC filter with the load resistance and also to show carrier frequency and filter roll-off. As a signal source, wideband noise generator was used. First... The amp has no balanced output or input. It is single ended. So using the term differential in describing U2 and U3 makes no sense. It is single ended, period.

LT1057: The two ends extend well, and the speed, dynamics and resolution are also quite good, but it is a cool tone. So again... I can vent the case, run fans, whatever.. The point is - we shouldn't have to do any of this. This is the frequency response into 4ohm. Note the 50kHz LC filter cut-off visible in individual output branches. Bluetooth: Version 5.2 Bluetooth support: 16-24bit 44.1-48khz Supported format: sbc/aac/aptx/aptx-hdAD712: The resolving power is very good, the sound is clear and without coloration, a very transparent feeling, the sound bottom is detailed, and the low frequency is slightly less.

This is why monitoring the temps of the voltage regulators is important. If you are experiencing temps over 158°F or 70°C. Then you will need to be concerned. Realize this.. I'm spearheading this endeavor alongside an electronics engineer who is well suited to the task. Doing this with the intention to save you all a load headaches in the future. You were all advised that I was working closely with the designer of the SparkosLabs op-amps. I am doing the work here so others can make an informed decision and avoid pitfalls. I am not here seeking advice, accolades, affirmation or validation. If any of you wanted to collaborate and work together, the door was always open. I am advising and guiding you through these processes and informing you. Let's try to remember this going forward. You didn't put a smiley face... You put a wink. These emoji's all have certain connotations and implications when used. They are all dependant on circumstances and sentiment. This is a biased article making fun of the concepts it speaks of and is not an accurate depiction of any of the characterizations.Conventional electronic components are designed to operate over a specified temperature range with upper limits generally set at 70°C for commercial applications, 85°C for industrial applications, and 125°C for military applications. You were fully abreast of the emergent situation and therefore your advisory statement was warranted and valid because it was from an informed position. Those 4 little nichicon 25v 10uf muse caps are an end-of-life product as far as my research has determined, so at some point these will be no longer available. Just a heads up on that one The amplifier switched off itself after about 1 minute of this test, due to overheating. However it has survived. Listening at levels that are really too high for extended listening, the amp barely warmed up at all. The MiniDSP was warmer.
