Spring 2 is out of production. Spring 3 is imminent. Not equivalent to May.
It's one of the best IMO!
I'm definitely liking my Spring 2 KTE better than my Morpheus. (Oops, others said this already: Spring 2 is discontinued. Spring 3 has been announced but it's not yet available for (pre-)order at Kitsune HiFi).
Better getting on the waiting list for the Spring 3...
What is it about the May that is so different from the regular Spring model?
Comparing KTE May vs KTE Spring 2 in the technical measurements thread results in the following summary:
Spring2 has lower residual noise
May has lower 19+20KHz IMD
May has slightly better Gain linearity at the lower levels (-120 to -140 dB)
May has better -120 dBFS sine resolution
May has lower THD+N vs frequency
May has slightly better jitter performance
May has a PLL jitter rejection enhancement
The differences are not huge but they are measurable.
FYI I think the only significant difference, for the 3rd version , seems to be the USB board.
Still people are definitely happy with theirs as v2 doesn't dig up very often, at least in Europe.
I think there's a volume control on Spring 3 that is new. Much as I hate to do this:
Right. But I believe it's an add-on, so you can get just the DAC too from what I gather.
Yes it's an add on and the estimated price (when I first saw it, a month or so ago) was 500.
Nice!! The preamp function is super handy for me. One of the reasons I purchased the Morpheus.
At 88 KHz to AES input and NOS filters the Wavelight has a much faster step response rise time with a short ring which is not usual for a NOS filter.
Red trace Wavelight - Blue trace KTE Spring 2
Wavelight NOS filter extends a bit higher than KTE Spring 2 for 88KHz to AES input and NOS filter
Yellow trace Wavelight - Blue trace KTE Spring 2
The above two measurements suggest a difference between the DACs that may present as a slight high frequency sparkle, edginess and leading edge hardness of the Wavelight over the KTE Spring 2 or a perceived smoothness of the KTE Spring 2 depending on which way one views the difference.
Per your request I reconfigured my Dante Digital Data Delivery System for 44 KHz and repeated the ABX comparison with Wavelight Lin and KTE Spring 2 OS filters.
The first day was challenging with a neighbor running a table saw and dust management vacuum (approximately 35 meters away) frequently throughout the day.
Aggregating two runs a total of 12 correct out of 16 challenges which meets the minimum for 95 % confidence for a binomial probability.
Second day a quiet ambient facilitated better ABX testing.
I also added two tracks to the listening evaluation:
Open Your Ears - Heartbeat
Joey DeFrancesco - jazz arrangement of Michael Jackson's Beat It
16 correct out of 16 challenges.
The differences observed in the original post remained audible.
Additionally the KTE Spring 2 had slightly more grunt noted with the two added tracks.
Again, these differences are slight and require focused critical listening to observe.
@atomicbob Nice work, and much appreciated!
This is the part where I move the goalposts, thought, right?
@Hands : I think you have the situation pegged.
