Pass Labs int 250

I know that Audio Doctor is recommending a product that they sell,  but I have to agree that the CSIB is at least a comparable product to the INT250.  Most people know that the Coda boys were engineers for Nelson.  Their products are excellent.  Its worth making a call to Doug Dale at Coda.  He is very honest and open about his products and how they compare with others.  Beware this amp is updated fairly regularly.  When technology changes come about they are incorporated into this amp.  The last few versions have all been great,  but the current is exceptional. 

I have the Pass 250.8 it's an excellent performer. As mentioned above you should give a number of amps a listen to see what you like.
That being said I don't think you'll be sorry with Pass equipment.

A friend had the int 250 with some British speakers, very uninvolving IMO. He thought so as well as he sold it after owning it for several months.

I had the pass  int250 with the bigger harbeth 40.2 and found it good but not.great.

The smaller harbeth probably a better fit with the integrated....

Personally for smaller harbeth if was getting integrated would also consider getting the VAC integrated ....

After many integrated ( plinius hiato, plinis 9200, mark levinson 508, Gryphon diablo 300, gamut 150LE, krell, marantz pm10, jeff rowland 500, luxman 509x, accuphase E-470) I'm now using pass int-250.
Is that the best one?, I don't think so. There is always something better. But  it gets me closer to live jazz and classical performances than any other ( gryphon diabllo is in the same category -  great integrated) and pass company is known for a great service.
One just need to feed pass int250 with a good source and good power, ICs and SCs cables to extract the best out of it. I directly compared luxman 509x and pass int250 in my system (esoteric k-03xs and sonus faber Amati Traditions). The pass int 250 has tighter and deeper bass, more organic mids and sweeter highs. But whats is even  more important for me its sounds more natural than Luxman 509x. There is quite reliable and truthful Czech based  website (they have option to read in English)  that publishes their reviews  - Audiodrom. They reviewed both integrated.
