The Baby Sumo is 600 watts @ 4 ohms, 300 @ 8 ohms and 150 @ 16 ohms.
Mike and I agreed on the following:
Tantra half amp/power, however that works, and gain matched by ear with the Sumo. Sort of it turns out.
We alternated Bass --> Tantra pre-amplifier --> Baby Sumo / Tantra -->and went with the MAS Bodai 110 as the control cab.
Highs were fairly close, not so much to call it a close tie, but the Tantra has a defined air whereas the Baby Sumo has a slightly veiled yet pleasant presentation.
Lows were similar with the Tantra seeming meatier for us both.
Morning after thoughts added here with cleaned up text from a TB private message I answered last night from someone interested in the Baby Sumo with most of the contents of that reply included.
I have cats that spent my nine hours of drive time and probably more sleeping. Breakfast for them is almost always in the 4:00 am time frame with after meal preening conducted in front of the great room stereo waiting for the soundscape clips from BBC America World News. Audiophile cats, go figure. A snack and a nap for me, from which I was roused by a flurry of E-mails from Europe on an unrelated topic. Android updates ensued so I brewed coffee fired up the laptop figuring I would try to stay on the routine schedule until a longer, deeper couch snooze/nap set in. Supposed to snow here anyway so.......
I heard the Sumo as going lower, with the low B having a pure even voicing on the Sumo.
The Tantra seemed to be more palpable. Presentation, for me, had the Sumo going "this is what I hear" while the Tantra said "this is what you want to hear".
The mid-range was different and we talked at length about the Sumo having more grind or a textured quality than the Tantra. Then Mike plugged in again. Lowered the volume on the Sumo as he felt that it was a bit louder and may be what we were hearing. Quick listen and we agreed that output was more closely matched. Several back and forth's later we agreed that the Sumo had more grind and the Tantra had cleaner, wider spread. But... they were very close and well into the different flavors of really good territory and thus down to personal preference.
Is the Baby Sumo, Grace Design AliX combo a Tantra killer?
Nope.
Head and shoulders above say Magellan, Subway D800, Aguilar TH500, LWA1000 and MT900?
Yup.
IMHO, and based on what I heard and what works for me.
Conforms to "you get what you pay for".
Considering price points alone they should be.
Mike's bottom line was that the Sumo beat the popular Ice 700 module in all categories and.... at the price, size point, was an absolute steal.
He figured, just spit balling, if he did something similar with his power module he would probably be north of $650.
The Baby Sumo, with shipping and import duty, was south of $500
BTW: Euro to U.S.D. was at 1.07 yesterday so the Baby Sumo is now going for less than I paid.
All pretty quick impressions, hope they help.
Thanks MrBEAR! Food for thought, or maybe GAS.
