Besides one comment, I haven’t seen anything about this tube amp on sbaf. Which is a bit of a shame, because despite being 1.5k, it’s a good enough tube amp to play ball with the totl stuff. I pretty much decided to get it due to @k4rstar 's positive comments and the fact that the company is located 20 minutes away from me. After a short demo, I paid the 1800 CAD and brought the amp back home. Specifications: Output Power : 8 watts per channel Tube Compliment : 6SL7 input/driver tube, EL 34 output tube, 5AR4 soft start rectifier Output impedance : 4, 8 ohms Voltage selectable: 115V/230V - switch located on bottom plate Frequency response: 20 hz- 20khz- flat Sensitivity: 300 mv full output Input impedance : 100K ohms S/N Ratio- 92 db Weight: 30 lbs Dimensions : 9.5” W x 12.5” D x 7” H Price : $1499 US http://www.coincidentspeaker.com/mpsip_amps.html Chain Audial Model S mk2 > Dynamo 34SE MKII > he-6 4 screw via speaker taps In a nut shell: Very transparent midrange and treble Fantastic resolution Great micro and macro dynamics Fast sounding transients with zero bloom, haze or veil Almost neutral sound without any brightness or harshness Good blackground Slight subbass bump, very textured Mids a tad lean lacking a bit of air Doesn’t have alot of tube magic Bass could be a tad tighter and sound as a whole could have a bit more heft 300 OI Headphone out (in practice doesn’t sound nearly as bassy as it would suggest), you can also change the OI on request SS like, not very tubey sounding What makes this amp so good is its combination of dynamics, resolution and transparency. There’s enough inner resolution and with great enough micro dynamics that I can feel the transients (is this what they mean by plankton?). The amp imparts little to none of it's timbre, I hear more of my audial’s nos sound and my he-6’s timbre than the amp’s coloration. There is a slight emphasis on the subbass and I could use more air, but that’s about it. The sound of the amp is more akin to a solid state, it’s definitely not for people that wants a warmer stereotypical tube sound but the dynamo still has a lot of what makes tube amps good. Like an accurate and not harsh treble, and overall lack of steeliness or hardness (but is not soft either) you get with a lot of SS amps. The fact that it is capable of sounding like this without sounding warm and using cheap Chinese tubes which together will probably cost much less than 100 usd is a feat in and of itself. The bass has a lot more authority than many tube amps I’ve heard. Again it’s very SS like, but I feel like it is missing that last bit of slam to compete with the super good SS amps. Disclaimer: My audial is definitely a bottleneck in terms of staging and bass, so while I felt the bass could be a bit tighter and weightier and have a more airy treble, I could probably fix these issues by changing the dac. I also bought some fancier tubes that should be incoming within the next few days Compared to my Decware Mini Torii Mk1 + better dynamics + better resolution + sharper imaging + better separation and detail + better clarity + more power + way less noisy - shallower stage - less air - leaner sounding - bass sounds a tad less deeper/tighter with dynamic headphones on the hp out Overall while the mini torii has a more pleasant colouration and is airier, it sounds more congested and slow in comparison to the Dynamo. Minus tonal balance and air the dynamo is markedly better in pretty much every other aspect. Non sound stuff I was kinda skeptical about the design but the mirror finish grew on me. It is very pretty at night. There is usually zero noise and humming. With only a bit on the he-6 in certain times of the day (usually morning) where my power is especially dirty. Even using a much easier to drive headphones like my MA900, there is only a barely noticeable hum. Outside of the high output impedance, you'll get the sound I mentioned above on the hp out. And even then the OI isn’t that bad in practice. None of my dynamic headphones (ma900, porta pro) sounded like farts on it. Pot is smooth, not the most buttery but gets the job done. The only flaws I can see is that you can’t switch between hp out and speaker out. It will power both at the same time if you plug a headphone and a speaker into it. It also runs pretty hot, almost as bad as the vintage McIntosh I owned last year.
