Left field idea.....what about an AV amp? Plenty of power if you pick a mid-range one.

I’m pretty happy with my Denon paired with my pre-anniversary 603’s. Music sounds good to my ears anyway

They are not as good as a hifi amp, OP want a new amp and with all the surround sound, extra channels input's,dsp, dac,digital inputs, hdmi,mic, speaker terminals there isn't as much used on the stereo part of the amp as there would be in a hifi amp for the same price, some amps are even class d to make shure the amps can fit in the cabinet and to keep heat lower than class a/b

They are all good amplifiers BUT personally within your budget, i will choose the Rotel RA1572 ( 120w x2 @ 8 ohms ) because it has good power and it comes from the same family as the Bowers & Wilkins.
Bowers and Wilkins no longer belongs to that group, it’s now owned by Sound United which covers Denon, Marantz and others.

I was not aware, it must have occured recently BUT thank you for the update
It was reported here, but it’s still a bit unclear to me who handles what in the UK. In the January 2021 Hifi News magazine there’s a review of Rotel and B&W kit, yet the Rotel supplier is listed at Rotel Europe/ B&W Group, West Sussex which sounds just like the old days. Who is importing Rotel if it isn’t B&W?

That same journal tests the speakers in question, and the impedance drops below 3 ohms at 124Hz, so a beefy amplifier is required. Regardless of who owns who, the Rotel above has more guts than the otherwise enjoyable Naim, so it would get my vote too. I’d not discount the Peachtree Nova that Rick mentioned either.

How do you deduce that the Rotel has more guts than the Naim? On paper specs alone? You may dislike Naim, but their amps are some of the most robust you’d find in terms of handling speaker loads. Don’t be fooled by its 60w/8ohm paper spec.

The power output of Rotel is 120w x 2 @ 8 ohms and this is twice the power output of Naim. Rotel has a far higher damping factor of 300 than Naim and this will help control with tighter grip the Bowers & Wilkins woofers than Naim

I think you need to audition both. The Naim should easily drive the 603s. The Nait 5si was measured to have actually 75w/channel before clipping. Don’t underestimate this amp.

In fact, I’d choose the Rega Elex-R over the Rotel too.

Totally agree. The best way to make a final decision is through auditioning. We can all throw in all sorts of suggestions but at the end of the day it all comes down to AUDITIONING, AUDITIONING, AUDITIONING ( similar to LOCATION LOCATION LOCATION in real estate )

It's all about current delivery I feel. Not dismissing Naim but Rotel are reknown for their ability to drive awkward loads...... which is why I own one.

Same here. Not that I don't like Rotel, but Naim are awesome at controlling speakers, and very, very surprising if you look at the specs. I'll also + 1 the Rogue Audio Sphinx suggestion.

Yes, exactly, it’s twice as powerful. As already pointed out by two other contributors, double the power is worth having especially for speakers with a rather awkward load. Unfortunately, I can’t find an independent test of the Rotel but here is a pretty favourable one for the Naim, which manages 76watts on test, and is okay as long as you don’t play at party volumes.
I don’t dislike the Naim, but I’m conscious of the tricky speaker load the 603 Anniversary presents.

Naim not to much power,lowest opf all the amps mentioned, does it get hot ?

From the sterophile review
I set it running at 20Wpc into that load. After 20 minutes, however, the amplifier turned itself off, indicated by the selected input button flashing. The chassis was very hot, with the left sidewall hottest at 118.1°F (47.8°C). I let the NAIT 5si cool down, then turned it on again. All was well, and I continued with my testing.

rotel more power more expensive

marantz might not have enough power 2x100 in 4 ohm,marantz PM8005 sounds okay but not more than avarage

rega fairly low price also a little short on power

hegel H90 discontinued ? Low power

In would go for min 2x100 in 8 ohm

no
What is your budget for streaming?
Would you consider an amplifier with streaming capabilities? (It might save money to have them combined)
no idea yet, as of now. need to choose first what amp to get.
