Hello ACHiPo,
Thank you so much for your reply and for sharing the link to your impressions for the Wavestream Kinetics Tube Phono Stage
I have admired Scott Frankland's design work for many many years, not just with the current Wavestream Kinetics tube gear, but also going back to the MFA ("M"Bruce Moore -"F" Scott Frankland - "A" Associates) years.
So, after having many conversations with Scott Frankland, on Feb 17 I placed a deposit with Scott for his current Wavestream Kinetic Level 5 Reference phono amp. His phono amp has always been on my "bucket list". It is an all tube design currently using (2 x 12AX7, 4 x 6DJ8); with extremely low noise (I believe with the external power supply that the current Level 5 Reference now comes with) noise is below 1uV (one-millionth of a volt ); providing 3 front panel selectable inputs = two MC at 62 dB of gain (without the use of SUT’s or FETS) with a useful cartridge range of 0.2mV to 1.2mV and one MM output at 42dB (you are able to choose your MM gain or you can have 3 MC ); having both balanced and RCA inputs and outputs; adjustable loading available on the back panel via custom loading plugs; and an essentially flat RIAA EQ curve within one tenth of a dB (.1dB) from 3 Hz to 40 Khz. *** The above specs are from the best of my recollection - if you have interest, please consult with Scott Frankland to confirm. He is wonderful to communicate with. ***
I have not received it yet, but I can certainly say that I am very excited to be able to hear it in my system. Scott is not only an excellent and talented designer, but is also a true gentleman and what I believe to be an asset to the audiophile community.
The current Wavestream Deluxe is actually in it’s Level 5 Reference iteration. Levels 1-3 were 5 tube configurations offering 60 dB of gain. The upgrade to Level 4 changed from 5 tubes to a 6 tube circuit using 4 x 6DJ8 & 2 x 12AX7. He said that there are several benefits over the previous 5-tube circuit....
1. Reduced crosstalk between channels gives more precise localization of images in complex material. The crosstalk was due to the shared 12AX7 in the 5 tube circuit.
2. Increased headroom allows bigger peak inputs without compression or harshness.
3. High-frequency bandwidth is extended to 50kHz. This improves leading edge transients (high-frequency detail, speed and air).
4. The output impedance has been reduced. This helps to cancel the adverse effects of cable capacitance and amplifier impedance. By the same means, the load presented by the RIAA network is isolated from the outside world.
5. Upgraded signal coupling caps provide better definition and a more natural tonal balance.
6. Both power supply regulators have been improved to optimize transient response.
I believe he said that the previous 5 tube units can be upgraded to the Level 4, six tube circuit with an upgraded audio board, numerous parts and power supply upgrades for about $2850. You will want to confirm this with Scott.
The current Level 5 Reference also now has an outboard power supply which I believe reduces the already impressive noise floor even lower.
I’m really excited and looking forward to having this as a major part of my vinyl system.
Wishing you all the very best of health, love and happiness!
