Help with first tube amp


I’m looking for some guidance on purchasing my first tube amp.

My current setup: Speakers: Sonus Faber Sonetto 1 G2 bookshelf speakers.  (I plan to add a subwoofer soon)

Amp/Source: Cambridge Audio EVO 150 (all-in-one integrated with built-in streamer & DAC)

The EVO 150 made sense originally because I didn’t have room for multiple components, but after some renovations I now have space and flexibility to build out a proper system.

Since this would be my first tube amp, I was hoping to keep costs reasonable and have been considering: •Muzishare X7 (KT88) •Cayin A-88T (KT88) •A used Muzishare R100 (300B) available locally •A used Brunoco Terra 6L6 PP available locally

My questions:

1.    ⁠Will I actually hear a meaningful difference between my EVO 150 and these lower-cost tube amps?
2.    ⁠Are my Sonus Faber Sonetto 1 G2s at 87 db sensitivity a good match for these lower-power tube amps ?
3.    ⁠Anything I should keep in mind as a first-time tube amp buyer who listens mostly to vinyl and streaming?
4.    ⁠What If I used the EVO 150 as a pre amp with the tube amp as power source only?  Would that still give me that tube sound ?

Thanks in advance — really appreciate any advice from folks with experience!

Your speakers are rated at 4 0hms nominal impedance, which means they probably dip below that and would be a bit of a hard load for the amps you mentioned and most budget tube integrateds.  You might consider a hybrid like this Unison Unico Due that has a tube input stage with solid state MOSFET output stage that’d give you some tube magic with solid state power to sufficiently power your speakers.  This seller offers 30-day returns if it doesn’t work out, which is nice.

Sonus Faber Sonetto 1 specs:

  1. Sensitivity 86 dB SPL (2.83 V/1m)
  2. Nominal impedance = 4 Ohm
  3. Recommended power amplifier 30 W - 150 W

Seems these speakers are not high efficiency but average efficiency needing current, so low watt amps not advised

Head in to https://resolutionavnyc.com/collections in Brooklyn and tell them what you’re looking for - they’re super helpful and can guide you in the right direction, plus you’ll get to check out some cool gear. (If chasing that tube sound) - you may want to dig in to the benefits of higher efficiency speakers and then checkout https://www.decwareproducts.com for their tube products.  I wish I would’ve known about them before I started my journey.  Very affordable - often touted as people’s ’absolute favorite’ amp at any price (under $2K). 

@licarijo - one store in the NYC area that sells tube amps? That don't sound right. I just did a search on hi-fi stores in the NYC Area and came up with quite a few of them just on Yelp, most of whom sell tube gear. But these are high-end stores that sell high-end brands, and often tube gear from those brands can be a bit pricey, but even those brands often have a variety of levels and prices.
