I have the A100t, and I am very pleased with both the sound and value. I have not heard the MT-100 so I cannot tell what the sonic differences are. Most likely the higher weight is due to different transformers and chaise. I sure Steve, the USA distributor for Cayin can provide more information about differences. Steve is the reason I purchased the Cayin. Great customer service.
Cayin A100T vs Spark MT-100k
Spark audio makes Cayin. They have an integrated named MT-100K under the Spark name that seems to have the same specs as Cayin A100T. The Spark model weighs about 7 lbs more than the Cayin model. Anyone heard the MT-100K ? Curious to know the differences between the models.
