Hmmm ... that sounds just like tube standby mode to me.

I applaud the fact that they have a standby mode, and that it's automated, but it amazes me why that's not more standard nowadays.  It used to be.

And with the quality of today's tubes it should be standard, especially for power amps.  Not preheating the filaments really decreases tube life.  I can't believe how much costly tube gear doesn't do this.

I just ordered one of these, along with the DiaLogue Severn Monoblocks. They'll be here next week, but I still have to get my speakers here so I can't try them yet!

Hi there.

Thanks for the honest review.

But why do you compare so speciffically to a pre amp 4 to 7 times the price? Wouldn't it be the same to compare it to an amp of say $400,00?

And then stating the differences?

In this way, allthough I insist on honesty and realism in audioreviewing, I always get the feeling that it is still not a very good amp. That it is 'only mid range' you will buy. Or am I the only one that feels that?

Why not compare this 2,6k amp a little bit more to Tube Pre Amps of about 2 to 4k? Or heck: even up to 6 or 7k? Instead of 10 to 18k? More from an upgrader's perspective?

Of course we still all do want to know how it compares to 10 to 18k amps... But the remark about the bass remains a bit unfair I think.. Even if you 'haste to remind'... It sticks with me anyway.

Because I look for an upgrade! I come from 'lower'. I have a top class Tentlabs cd player of $4600 (please do review sometime!) and a Power Amp of about $3300.

My Pre Amp is a modified Rotel RC 995 of about $1000. So although this thing is still surprisingly good, it's still also my 'bottleneck'. I know I have some very top class speakers allready too and my room and setup are other topics of course (not bad at all).

So I'm looking for a Pre Amp upgrade: say about $2600! So I want more comparison to 2-4k amps, not speciffically to 10 or 18k amps, reviewing a 2,6k amp... 

Allthough it's a fair remark and I'm sure you meant that it is very good at it's price (which you also stated..), in my humble opinion you still end the review with a touch of 'looking downward' on this amp.. And I don't say that because I'm dutch just like the amp... But because I'm 'looking upward'...

Anyway. You're not a salesperson for Prima Luna (neither am I). So thanks for the effort and for the honest information.

Maury: how are they?

This thing is good looking for a pre-amp under $3,000. Why do others look like small simple metal boxes with tubes on top; AVM looks average though. If stereophile raves over it, then it I trust their opinion even though I would jump at the chance of an audition at a dealer. That tells you a lot, but half of what it will sound like with my interconnects, non thousand dollar speakers and components. The only way is to buy everything in the artice (a dream) or just buy the Dialogue 3 and see.

I hope you answer this question.  Why is it that you can get an integrated Primaluna for only a few hundred dollars more than the pre amp alone?  I've also read rave reviews about the integrateds but would I be better off with the pre amp and using my existing (Hafler Transnova)?  I guess I'm finding it hard to believe that a pre amp with a few hundred dollar amp section could be as good as a separate amp even though it's really old.  Primaluna price points makes things very confusing.  Not just that but the fact that I have not found. A dealer where I can compare the integrated and the pre amp with a separate amp.
