Manley Stingray Integrated amp.

The Stingray is a very nice amplifier indeed.

In addition to having one of the champs of tone, the EL84, it is well built and should prove reliable. You're also dealing with one of the better companies in the business, normally represented by some of the better dealers in the business - and, no, that's not a coincidence. So, you'll be well supported. Don't discount the fact that the amp is made in the USA as one of the big reasons behind this.

I'm also partial to the aesthetic, but understand that's a matter of personal taste. My one caution is that the amp is definitely not the last word in power, so keep that in mind.

Regarding how newer amps compare to older ones, I'm also increasingly discovering as time passes how special those vintage tube amps truly are.

Along the lines of what Pubul57 laid out, I think you can't go wrong with an amplifier from Roger Modjeski, Manley, or VAC. Which particular model best suits you will be a matter of personal taste, and I encourage you to do a bit of auditioning, if possible.

See my previous comments on the Stingray - when you align yourself with companies such as these three, it's difficult to imagine coming out on the wrong side of the coin.
