Cambridge Audio axa35 integrated amplifier ?

The Cambridge AXA 35 rocks, great budget amp with loads of great reviews to back it up.  I had it and heard it , its tough to beat a $350.

The Tekton Lore speakers are efficient and an easy load for an amplifier.   I don’t play music loud given my age and tinnitus.   So my focus here is the quality of the music versus loudness.   

Well, you want some 'warmth' and don't need a phonostage or a DAC. Maybe find a used NAD 326BEE.  I've been a fan of NAD class A/B integrateds. Have owned the 326 and 356 BEEs in recent years.

I must say the Cambridge AXA35 seems a strong contender at that budget. I have not heard it however.  The Schiit DAC is likely superior to the one in the Yamaha 301 which I've heard and have recommended at that budget. A great option for budget system serving both vinyl and digital. Again, you need amplification only, owning a disc player and DAC.

I am not familiar with the Onkyo. 

As an after thought, it is best to keep digital components separate from amplification when possible. Each having their own power supply. Given you have a DAC I would choose between the Cambridge or the Onkyo. They have similar feature sets. The Onkyo does have  tone controls that can be bypassed, a nice feature. I believe the fit and finish of the Cambridge to be better. 

Several on line dealers offer 60 day returns. 

OK, my final answer, I would give the Cambridge a try. Will likely play well with your Tektons.  

According to write up on Cambridge AXA35 the balance and time controls are buried in menu but usable
